Studies on initial landform evolution are often limited to relatively small-scale experiments or rely on modeling exercises. Larger-scale experiments can be carried out in constructed hydrological catchments with well-known and documented initial conditions. The central aim of this work was to describe the hydro-geomorphic surface structure evolution during the initial years of ecosystem development, its dependence on initial and boundary conditions; and on its relations to hydro-geomorphic connectivity. The data are from the 6-ha, constructed hydrological catchment 'H{\"u}hnerwasser'. Hydro-geomorphic development was quantified using a combined analysis of digital elevation models and aerial photographs. Empirical results were compared with those obtained with a numerical landscape evolution model. Phases of rill network growth, contraction and stabilization could be characterized. Results show influences of initial morphology, precipitation characteristics, and developing structure-process-interactions on rill network geometry and connectivity increase in the catchment.

RCHs consist mostly of Auh horizons that are substantially enriched in soil organic carbon (SOC), of which the largest part seems to be of pyrogenic origin (PyC). However, the reported range of SOC and PyC contents in RCH soil also suggests that they are enriched in nonpyrogenic SOC. RCH soils are discussed as potential benchmarks for the long-term influence of biochar amendment and the post-wildfire influences on soil properties. In this study, we utilised a large soil sample dataset (n = 1245) from 52 RCH sites in north-western Connecticut, USA, to quantify SOC contents by total element analysis. The contents of condensed highly aromatic carbon as a proxy for black carbon (BC) were predicted by using a modified benzene polycarboxylated acid (BPCA) marker method in combination with diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy-based partial least square regression (r2 = 0.89). A high vertical spatial sampling resolution allowed the identification of soil organic matter (SOM) enrichment and translocation processes. The results show an average 75\% and 1862\% increase in TOC and BPCA-derived carbon, respectively, for technogenic Auh horizons compared to reference soils. In addition to an increase in aromatic properties, increased carboxylic properties of the RCH SOC suggest self-humification effects of degrading charcoal and thereby the continuing formation of leachable aromatic carbon compounds, which could have effects on pedogenic processes in buried soils. Indeed, we show BPCA-derived carbon concentrations in intermediate technogenic Cu horizons and buried top/subsoils that suggest vertical translocation of highly aromatic carbon originating in RCH Auh horizons. Topmost Auh horizons showed a gradual decrease in total organic carbon (TOC) contents with increasing depth, suggesting accumulation of recent, non-pyrogenic SOM. Lower aliphatic absorptions in RCH soil spectra suggest different SOM turnover dynamics compared to reference soils. Furthermore, studied RCH soils featured additional TOC enrichment, which cannot be fully explained now.}, language = {en} } @inproceedings{SchneiderGerkeMaureretal., author = {Schneider, Anna and Gerke, Horst H. and Maurer, Thomas and Raab, Thomas}, title = {Initial phases of landform evolution in a small catchment}, series = {European Geosciences Union, General Assembly 2014, Vienna, Austria, 27 April - 02 May 2014}, booktitle = {European Geosciences Union, General Assembly 2014, Vienna, Austria, 27 April - 02 May 2014}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, abstract = {During initial phases of landform evolution, the surface of sediment bodies is commonly not yet equilibrated with the environmental conditions and is thus liable to rapid changes by accelerated geomorphic activity.

The development of such systems, however, has frequently been assumed to depend on boundary and initial conditions including the solid phase. Here, an experimental watershed of about 6 ha surface area was artificially-created in order to imitate an initial stage just at the beginning of the geo-ecosystem development. However, sediment homogeneity could not be achieved for this large-scale field experiment, and the 3D spatial distribution of structures and components remained uncertain. The objective of this study was to quantify and reconstruct the initial sediment distribution and the first development stages using aerial photographs, point information, and a 3D model. The watershed was made of coarse-textured sediments of quaternary origin with a low permeable clay liner as the bottom boundary. A 2D horizontal digital elevation model (DEM) of the surface and a DEM of the subsurface clay layer are used to construct a 3D triangulated numerical grid of the catchment's initial spatial structure using the 3D-GIS software GOCAD. Physical and chemical soil properties obtained from borehole samples are assigned to this model and interpolated onto the 3D grid. The volumetric changes in space and time are quantified and related to material properties to obtain the mass changes. Correlations between terrain attributes, sediment properties, and mass changes are explored specifically in regions of differing source materials. A temporal sequence of surface DEMs is obtained from photogrammetric, high-precision ground based laser scanning and airborne laser scanning data. 3D models of elevation change are constructed from these DEMs. The processes following the initial state are mainly characterized by runoff-induced erosive mass relocations related to the distribution of surface and subsurface structures and sediment properties. The results suggest that both sediment structures and mass translocations differ between the western and eastern parts of the watershed and that correlations between initial surface structures and subsequent mass changes exist.}, language = {en} } @misc{ReifSchneiderWolfframmetal., author = {Reif, J{\"u}rgen and Schneider, Thomas and Wolfframm, Dirk and Schmid, Reiner P.}, title = {Femtosecond nonlinear optical characterisation of silicon wafers: the role of symmetry}, series = {Materials Science in Semiconductor Processing}, volume = {4}, journal = {Materials Science in Semiconductor Processing}, number = {1-3}, issn = {1369-8001}, doi = {10.1016/S1369-8001(00)00166-9}, pages = {241 -- 243}, language = {en} } @inproceedings{SchmidSchneiderReif, author = {Schmid, Reiner P. and Schneider, Thomas and Reif, J{\"u}rgen}, title = {Ultrafast transient grating in Barium Fluoride efficient instantaneous optical switching, and frequency conversion on a femtosecond time scale}, series = {Bragg gratings, photosensitivity and poling in glass waveguides, postconference digest, Stresa, Italy, July 4 - 6, 2001}, booktitle = {Bragg gratings, photosensitivity and poling in glass waveguides, postconference digest, Stresa, Italy, July 4 - 6, 2001}, publisher = {OSA}, address = {Washington, DC}, isbn = {1-557-52681-8}, language = {en} } @misc{SchneiderReif, author = {Schneider, Thomas and Reif, J{\"u}rgen}, title = {Influence of an ultrafast refractive index grating on nonlinear optical phenomena}, series = {Physical Review A}, volume = {65}, journal = {Physical Review A}, number = {2}, issn = {1094-1622}, pages = {023801}, language = {en} } @inproceedings{SchmidSchneiderReif, author = {Schmid, Reiner P. and Schneider, Thomas and Reif, J{\"u}rgen}, title = {Ultrafast Transient Grating in Barium Fluoride Efficient Instantaneous Optical Switching, Frequency Conversion and Simple Logic Operations on a Femtosecond Time Scale}, series = {Ultrafast electronics and optoelectronics, January 10 - 12, 2001, Lake Tahoe, Nevada, proceedings volume}, booktitle = {Ultrafast electronics and optoelectronics, January 10 - 12, 2001, Lake Tahoe, Nevada, proceedings volume}, editor = {Chen, K. and Rodwell, Mark and Knox, Wayne}, publisher = {OSA}, address = {Washington, DC}, isbn = {1-55752-606-0}, pages = {111 -- 112}, language = {en} } @misc{SchneiderGerkeMaureretal., author = {Schneider, Anna and Gerke, Horst H. and Maurer, Thomas and Seifert, Stefan and Nenov, Rossen and H{\"u}ttl, Reinhard F.}, title = {Evaluation of remotely-sensed DEMs and modification based on plausibility rules and initial sediment budgets of an artificially-created catchment}, series = {Earth Surface Processes and Landforms}, volume = {37}, journal = {Earth Surface Processes and Landforms}, number = {7}, issn = {1096-9837}, pages = {708 -- 725}, language = {en} } @misc{MaurerSchneiderGerke, author = {Maurer, Thomas and Schneider, Anna and Gerke, Horst H.}, title = {Scenario-Based Three-Dimensional Distributed Sediment Structures for a Constructed Hydrological Catchment}, series = {Vadose zone journal}, volume = {12}, journal = {Vadose zone journal}, number = {4}, issn = {1539-1663}, doi = {10.2136/vzj2013.02.0047}, abstract = {Many processes in a developing catchment can only be fully understood if the spatial heterogeneity is adequately described.

Filling and compaction are modeled based on three-dimensional volume analysis and mass balances of dumped sediments.

Data were from the constructed catchment "Chicken Creek." The initial texture and bulk density distributions were generated by imitating sediment dumping, segregation, and compaction. Boundary geometries and changes in surface topography due to erosion and sedimentation processes were quantified on the basis of digital elevation models (DEMs) derived from aerial photographs. The catchment was visualized with the three-dimensional software GoCad; the "emergence" of the water table and other structures (e.g., soil horizons, root zone) could be spatially assigned and quantified to identify regions with specific processes. A combination of three-dimensional catchment with time-dependent two-dimensional surface models allowed generating the development of spatially distributed erosion-deposition patterns that formed new initial surfaces. The three-dimensional distributed solid phase structure of the catchment allowed for a more direct comparison with observations using minimal invasive methods. The mass balance of the solids could be related with pedologic development and transfer to other geopedologic systems achieved by adapting sediment transport and deposition in the descriptions of the model.

To ensure unaffected development, the study was largely restricted to the analysis of remotely-sensed data. We analyzed a series of photogrammetry-based digital elevation models (DEMs) for 10 points in time, over a period of five years and beginning with the initial state. The evolving erosion rill network was quantitatively described based on mapping from aerial photographs. DEMs and rill network maps were combined to specifically analyze the development of morphometry for different parts of the network and to characterize energy dissipation and connectivity. The restriction to remote-sensing data did not allow for analyzing specific processes governing rill network development, nevertheless, two major development phases could be characterized. We observed a phase of growth of the rill network along with variations in drainage patterns during the first two years of development and a subsequent phase of reduction of its area along with comparably stable patterns. Region-specific analysis of morphometry indicates that, besides effects of changing sediment characteristics and vegetation cover development, locally evolving hydro-geomorphic feedback cycles influenced this development. Results show an increasing similarity of overall statistical characteristics (e.g. drainage density) for two parts of the catchment, but a persistent influence of initial conditions on specific rill geometry. The observed development towards higher orderliness and increased connectivity is consistent with experiments and concepts on drainage network evolution across scales; however, we did not observe major influences of rill piracy and cross grading or a reduction of energy dissipation with network development.}, language = {en} } @misc{SchneiderTaklaNicolayetal., author = {Schneider, Anna and Takla, Melanie and Nicolay, Alexander and Raab, Alexandra and Raab, Thomas}, title = {A Template-matching Approach Combining Morphometric Variables for Automated Mapping of Charcoal Kiln Sites}, series = {Archaeological Prospection}, volume = {22}, journal = {Archaeological Prospection}, number = {1}, issn = {1099-0763}, doi = {10.1002/arp.1497}, pages = {45 -- 62}, abstract = {Analysing the spatial distribution of anthropogenic relief structures can contribute to the understanding of past landuse systems.

The study site is located north of Cottbus, Germany, where an exceptionally large historic charcoal production field has been documented in previous archaeological surveys. The goal of this study was to implement, evaluate and improve an automated GIS-based routine for mapping these features based on the template-matching principle. In addition to the DTM, different morphometric variables were evaluated for their suitability to detect kiln sites. The mapping results were validated against a comprehensive database of kiln sites recorded from archaeological excavations and via manual digitization. The effects of irregular kiln-site geometry and DTM noise were evaluated using synthetic DTMs. The results of the synthetic DTM mapping show that the template-matching results differed depending on the morphometric variable used for the mapping process. In accordance with this observation, a validation of the mapping procedure for the field site suggests that feature mapping can be improved. In particular, the number of false detections can be reduced using a combination of morphometric variables. For the validation area, the kiln sites with diameters of at least 10m were mapped using the automated routine, with detection rates that were close to those of manual digitization.

Models of the 3D subsurface structure and the soil heterogeneity have often been built based on geostatistical approaches and conditional simulations for spatial interpolation between measurements. Here, an alternative model was proposed that generated 3D subsurface structures by imitating basic structures resulting from mass distribution processes. Instead of directly assuming stochastic variations of the subsurface structure, the present approach assumed stochastic variations in parameters of the process-based algorithms of the generator models. The constructed hydrological catchment "H{\"u}hnerwasser" located in the Lower Lusatia region of Brandenburg, Germany, was used as an example for the development of such a 3D structure generator model. Boundary geometries and changes in the surface topography due to erosion and sedimentation processes were quantified on the basis of digital elevation models (DEMs) derived from aerial photographs and terrestrial laser scanning information. Basic sediment properties came i) from a geological model of the parent material at the outcrop site, ii) from actual soil sample measurements on-site, and iii) based on stochastic texture variations. Sediment distributions were generated according to construction processes such as sediment dumping, particle segregation, and soil compaction. The resulting internal structures reflect the formation of spoil cones and surface compaction by machinery. The simulated 3D model scenarios of soil texture and bulk density distributions were incorporated in a gridded 3D volume model using the 3D software tool GoCAD (Paradigm Ltd.). This 3D distributed solid phase structure of the catchment allowed for a more direct comparison with observations using minimal invasive methods. By including structural changes over time (e.g., derived from DEM's), spatially-distributed solid mass balances can be inferred based on the comparison of 3D structure models for subsequent time steps, which is a basic information for studying soil development. The 3D structure model as spatial database of the solid phase allows an integrative analysis, a periodical mass balance, and a mechanistic process-based generation of complex realizations of distributed hydraulic model parameters for the exemplary catchment.}, language = {en} } @misc{LuisZhuCostaetal., author = {Luis, Leonel and Zhu, Hong and Costa, Jo{\~a}o and Valls-Sol{\´e}, Josep and Brandt, Thomas and Zhou, Wu and Schneider, Erich}, title = {Reply to the commentary on luis et al.

Geomorphological processes in (pre)history may have resulted in a modification of the local relief around archaeological sites, especially in areas that are prone to sediment erosion and relocation, such as sheet sand and dune landscapes. In this study, we reconstructed and analysed the palaeorelief of an archaeological excavation site in an inland dune area in southern Brandenburg, Germany. The remains of two Mesolithic sites were documented in the archaeological excavations and found to be associated with a buried soil horizon. To gather information on the relief of the buried soil surface, we used a combination of sedimentological and pedological profile descriptions along archaeological survey trenches and geophysical prospection with ground penetrating radar supplemented with microdrone photography and photogrammetry, global positioning system (GPS) surveys, and analysis of LiDAR-based elevation models. A digital elevation model of the buried surface was generated and analysed using a geographical information system (GIS). A comparison of the palaeosurface model with the recent surface elevation model shows that sand remobilization resulted in a considerable reshaping of the relief. Further, an analysis of the buried surface model shows that the relief position of the two archaeological sites in the study area was considerably more prominent in relation to the corresponding buried soil surface than in relation to the recent surface morphology.

Studies on extensive outcrops that address geomorphology, pedology and archaeology provide unique insights into human-induced environmental changes. Our approach uses a variety of traditional and cutting-edge techniques to characterize small-scale landforms (high-resolution DEMs by micro-drone and LiDAR), to analyze soils and substrate properties in the field (GPR, ERT, geomagnetics, Field Portable XRF and XRD) and to provide chronological information (OSL, 14C, tree-ring dating). This approach is combined with a GIS for data integration. We present the most recent results and review important findings from the last several years. Studies conducted in the opencast mines focus on soil development and Late Quaternary geomorphodynamics and as well as past land use and the legacy of agriculture and woodland use. Our results regarding the human-induced geomorphodynamics are similar to those in other regions in Central Europe, but we also observe regional differences caused by the local setting, e.g., intensification of soil erosion coinciding with the expansion of farming of cultivated lands in the Slavic Middle Ages. By analyzing LiDAR data the largest area of historical charcoal production in the Northern European Lowland (NEL) has been revealed. We are clearly only beginning to understand the massive dimensions of charcoal production in the region and the impact on late Holocene geomorphodynamics. The usage of new high-resolution imagery is essential to identify small-scale anthropogenic landforms hidden in the landscape. Future work will consist of developing and improving our integrative approach.

We applied a combination of methods for mapping such kiln relicts across a range of scales, in order to analyze the spatial distribution of kiln sites and to improve the understanding of historic forest use systems. In archaeological excavations in the mine forefield, the geometry of kiln relicts could be studied in high detail.

Charcoal production can have numerous effects on ecosystems, e.g., through changes in forest area and structure, or through the effects of pyrolysis, charcoal and ash addition to soils.

In the forefield of the open-cast mine J{\"a}nschwalde (north of Cottbus, Germany), archaeological excavations have revealed one of the largest charcoal production fields described so far.

The remains of charcoal hearths are therefore a widespread legacy of historic land use in forest areas. Soils on charcoal hearth sites are characterized by a technogenic layer rich in charcoal and ash on top of the soil profile, and by a pyrogenic modification of substrates below the former hearth. The aims of our study are to examine how these alterations to the natural soil profiles affect the soil water regime and other soil physical properties, and to assess the relevance of these effects on the landscape scale. We present first results of a mapping of hearth site occurrence in forest areas in the state of Brandenburg, Germany, and of a characterization of the infiltration behaviour on hearth sites as compared with undisturbed forest soils. Results of mapping small-scale relief features from LIDAR-based digital elevation models show that charcoal hearths occur in a high density in many large forest areas throughout Brandenburg. In the areas studied so far, up to almost 3\% of the soil surface were found to be affected by the remains of historic hearths. First analyses of soil physical properties indicate differences in the infiltration characteristics of hearth site soils and undisturbed forest soils: Hood infiltrometer measurements show a very high spatial variability of hydraulic conductivity for hearth site soils, and water-drop-penetration-time tests reflect extremely high hydrophobicity of the technogenic layer on the sites. Results of dye tracer experiment show considerably strong preferential flow and therefore a higher spatial variability of soil wetness below the hearth remains. Overall, our first results therefore indicate that the legacy effects of historic charcoal production might significantly affect overall site conditions in forest areas with a high density of charcoal hearth remains.}, language = {en} } @inproceedings{HirschSchneiderRaabetal., author = {Hirsch, Florian and Schneider, Anna and Raab, Alexandra and Raab, Thomas and Ouimet, William and Dethier, David}, title = {Late Holocene biochar enrichment in soils - implications of an anthropogenic legacy for ecosystems}, series = {ICLEA Final Symposium 2017, Human Impact and Landscape Evolution in the Southern Baltic Lowlands, Abstract Volume \& Excursion Guide}, booktitle = {ICLEA Final Symposium 2017, Human Impact and Landscape Evolution in the Southern Baltic Lowlands, Abstract Volume \& Excursion Guide}, editor = {Schwab, Markus and Błaszkiewicz, Mirek and Raab, Thomas and Wilmking, Martin and Brauer, Achim}, publisher = {GFZ German Research Centre for Geosciences}, address = {Potsdam}, doi = {10.2312/GFZ.b103-17037}, pages = {79 -- 81}, language = {en} } @inproceedings{SchneiderHirschRaabetal., author = {Schneider, Anna and Hirsch, Florian and Raab, Alexandra and Raab, Thomas}, title = {Dye tracer visualization of infiltration patterns in soils on historic charcoal hearth sites}, series = {ICLEA Final Symposium 2017, Human Impact and Landscape Evolution in the Southern Baltic Lowlands, Abstract Volume \& Excursion Guide}, booktitle = {ICLEA Final Symposium 2017, Human Impact and Landscape Evolution in the Southern Baltic Lowlands, Abstract Volume \& Excursion Guide}, editor = {Schwab, Markus and Błaszkiewicz, Mirek and Raab, Thomas and Wilmking, Martin and Brauer, Achim}, publisher = {GFZ German Research Centre for Geosciences}, address = {Potsdam}, doi = {10.2312/GFZ.b103-17037}, pages = {150 -- 151}, language = {en} } @inproceedings{SchneiderHirschWechleretal., author = {Schneider, Anna and Hirsch, Florian and Wechler, Klaus-Peter and Raab, Alexandra and Raab, Thomas}, title = {Mapping a palaeosurface and archaeological site location in an anthropogenic drift sand area}, series = {ICLEA Final Symposium 2017, Human Impact and Landscape Evolution in the Southern Baltic Lowlands, Abstract Volume \& Excursion Guide}, booktitle = {ICLEA Final Symposium 2017, Human Impact and Landscape Evolution in the Southern Baltic Lowlands, Abstract Volume \& Excursion Guide}, editor = {Schwab, Markus and Błaszkiewicz, Mirek and Raab, Thomas and Wilmking, Martin and Brauer, Achim}, doi = {10.2312/GFZ.b103-17037}, pages = {152 -- 154}, language = {en} } @inproceedings{SchneiderRaabHirschetal., author = {Schneider, Anna and Raab, Alexandra and Hirsch, Florian and Bonhage, Alexander and Raab, Thomas}, title = {Assessing the legacies of historical charcoal production in Brandenburg}, series = {ICLEA Final Symposium 2017, Human Impact and Landscape Evolution in the Southern Baltic Lowlands, Abstract Volume \& Excursion Guide}, booktitle = {ICLEA Final Symposium 2017, Human Impact and Landscape Evolution in the Southern Baltic Lowlands, Abstract Volume \& Excursion Guide}, editor = {Schwab, Markus and Błaszkiewicz, Mirek and Raab, Thomas and Wilmking, Martin and Brauer, Achim}, publisher = {GFZ German Research Centre for Geosciences}, address = {Potsdam}, doi = {10.2312/GFZ.b103-17037}, pages = {155 -- 156}, language = {en} } @inproceedings{HirschBauriegelBonhageetal., author = {Hirsch, Florian and Bauriegel, Albrecht and Bonhage, Alexander and Schneider, Anna and Raab, Thomas}, title = {Fuchserden in Brandenburg - Vorkommen, Mikromorphologie und Bodenchemie}, series = {Abstracts der Jahrestagung der Deutschen Bodenkundlichen Gesellschaft, G{\"o}ttingen, 2017}, booktitle = {Abstracts der Jahrestagung der Deutschen Bodenkundlichen Gesellschaft, G{\"o}ttingen, 2017}, publisher = {DBG}, address = {G{\"o}ttingen}, pages = {1}, language = {de} } @incollection{SimonSchneiderRiederetal., author = {Simon, Sylvio and Schneider, Robert and Rieder, Thomas and Hernschier, Stephan and Magister, Jan}, title = {Untersuchungen zum Laufverhalten von Tragrollen}, series = {20 Jahre IURS e.V. - Res{\"u}mee und ausgew{\"a}hlte Projekte 2012 - 2017}, booktitle = {20 Jahre IURS e.V. - Res{\"u}mee und ausgew{\"a}hlte Projekte 2012 - 2017}, edition = {1.

Methods A group of 18 patients with TGA performed an established real-space navigation paradigm, requiring allo- and egocentric spatial orientation abilities, 3 days (postacute stage) and 3 months (follow-up) after symptom onset. Visual exploration behavior and navigation strategy were documented by a gaze-controlled, head-fixed camera. Allo- and egocentric spatial orientation performance was compared to that of 12 age-matched healthy controls. Navigation-induced brain activations were measured using [18F]-fluorodeoxyglucose-PET in a subgroup of 8 patients in the postacute stage and compared to those of the controls. Results In the postacute stage, the patients navigated worse and had higher error rates than controls in allocentric (p = 0.002), but not in egocentric, route planning (p = 0.30), despite complete recovery of verbal (p = 0.58) and figural memory (p = 0.11). Until follow-up, allocentric navigation deficits improved, but higher error rates and reduced use of shortcuts persisted (p < 0.0001). Patients still exhibited relatively more fixations of unique landmarks during follow-up (p = 0.05). PET measurements during the postacute stage showed increased navigation-induced brain activations in the right hippocampus, bilateral retrosplenial, parietal, and mesiofrontal cortices, and cerebellar dentate nucleus in patients compared to controls (p < 0.005). Conclusions Patients with TGA show selective and prolonged deficits of allocentric spatial orientation. Activations in right hippocampal and extrahippocampal hubs of the cerebral navigation network functionally substitute for the deficit in creating and updating the internal cognitive map in TGA.}, language = {en} } @misc{BonhageRaabRaabetal., author = {Bonhage, Alexander and Raab, Thomas and Raab, Alexandra and Schneider, Anna and Ramezany, Shaghayegh and Ouimet, William}, title = {Pyrogenic carbon in temperate forests - long-lasting impact of historical charcoal production on soils and ecosystems}, series = {EGU General Assembly 2022, Vienna, Austria, 23-27 May 2022}, journal = {EGU General Assembly 2022, Vienna, Austria, 23-27 May 2022}, doi = {10.5194/egusphere-egu22-8312}, abstract = {Pre- and early industrial charcoal production has left a striking legacy effect on today's soil landscapes in many forests of Central Europe and the North Eastern USA. Charcoaling in upright standing hearths (also called kilns) resulted in distinct circular micro relief structures, easily identifiable today in the field and on high resolution LiDAR-based digital elevation maps. Soils on these sites are characterized by one or multiple layers of decimetre thick charcoal rich substrate, which makes them Spolic Technosols according to the WRB soil classification. The focus of research on these sites increasingly deals with the difference of their soil physical and chemical properties in relation to unaffected forest soils and the potential implications for changes in vegetation and faunal growth. The controlling factor thereby is the soils large content of charcoal in various particle sizes, ranging from fine dust to large chunks. Studies have repeatedly shown the soils significant increase in total organic- and pyrogenic carbon content. The increase in total carbon stocks is thereby not only caused by pyrogenic carbon, but also by an apparently increased accumulation of non-pyrogenic organic matter. Here we present the latest findings regarding the carbon contents of centennially old charcoal rich technogenic substrates, sampled as part of multiple research projects in Brandenburg, Germany and the Litchfield hills in North-western Connecticut, USA. A focus will be the determination of highly aromatic carbon by the molecular marker Benzene-polycarboxylic acid (BPCA) and its prediction by FTIR-MIR chemometric methods.

In this context, soil conditions may play a crucial role, since they determine the availability of water and nutrients for trees. Yet, effects of systematically differing soil conditions on tree growth render a marginally studied topic. In this context, relict charcoal hearths (RCH) - a widespread legacy of anthropogenic charcoal production - render a valuable 'natural' experiment to study possible effects of artificially altered soil conditions on tree growth. We hypothesize, that the differing physico-chemical properties of RCH result in differing wood properties if compared to trees growing on unmodified soils. To test this hypothesis, we analyzed tree-growth, wood density, and wood elemental concentrations of Scots pine as well as physico-chemical soil properties. We applied a classic control-treatment design to compare RCH with unmodified soils. Our analyses identified significantly lower above-ground wood production but systematically higher wood elemental concentrations in RCH-trees compared to control trees. Since we could not identify treatment-specific growth patterns, we hypothesize the observed lower above-ground productivity of Scots pine to indicate an increased root-shoot ratio to compensate for a potentially lower plant water availability on RCH-sites. The observed higher wood elemental concentrations likely reflect higher soil elemental concentrations of Fe, Ca, K, and Mn in RCH soils. In conclusion, our study highlights diverse effects of RCH on tree growth and wood properties and strengthens the value of dendro-chemistry to use the tree-ring archive as proxy for soil conditions within a dendro-ecological context.}, language = {en} } @misc{KordaZamaroWagneretal., author = {Korda, Athanasia and Zamaro, Ewa and Wagner, Franca and Morrison, Miranda and Schneider, Erich and Caversaccio, Marco Domenico and Sauter, Thomas C. and Mantokoudis, Georgios}, title = {Acute vestibular syndrome: is skew deviation a central sign?}, series = {Journal of Neurology}, volume = {269}, journal = {Journal of Neurology}, number = {3}, issn = {1432-1459}, doi = {10.1007/s00415-021-10692-6}, pages = {1396 -- 1403}, abstract = {Objective Skew deviation results from a dysfunction of the graviceptive pathways in patients with an acute vestibular syndrome (AVS) leading to vertical diplopia due to vertical ocular misalignment.

Methods We performed a prospective study from February 2015 until September 2020 of all patients presenting at our emergency department (ED) with signs of AVS. All patients underwent clinical HINTS and video test of skew (vTS) followed by a delayed MRI, which served as a gold standard for vestibular stroke confirmation. Results We assessed 58 healthy subjects, 53 acute unilateral vestibulopathy patients (AUVP) and 24 stroke patients. Skew deviation prevalence was 24\% in AUVP and 29\% in strokes.

The sensitivity of vTS was 29.2\% with a specificity of 75.5\%. Conclusions Contrary to prior knowledge, skew deviation proved to be more prevalent in patients with AVS and occurred in every forth patient with AUVP. Large skew deviations (> 3.3 deg), were pointing toward a central lesion.

Charcoal hearths are round to elliptical forms often around 10 m in diameter, and consist of several decimeter thick layers that contain charcoal fragments, ash, and burnt soil. We studied the soil chemistry of 24 charcoal hearths and compared them to the surrounding 'natural' soils in the northern Appalachians of northwestern Connecticut. The thickness of the topsoils on the charcoal hearths and their carbon content are remarkably higher than in the surrounding topsoils.

We studied soils at former charcoal production sites (relict charcoal hearths, RCHs) and compared these soils with undisturbed soil next to the charcoal hearths and four typical soils on similar parent material located at distances between 10 and 70 km from the RCHs. In a landscape typical of the northern German lowland, we found Podsolige Braunerde [WRB: Brunic Arenosols (Protospodic)] outside of the RCHs and soils with a clearly different stratigraphy within the RCHs. The main feature of the soils at both of the studied RCHs is a heterogeneous, charcoal-bearing deposit that is ~30 cm thick. No indications of translocation or mineral transformation processes, which form distinct soil horizons after the deposition of anthropogenic material on the RCHs, are present. Except for the differences in color and total carbon content, the soil chemistry of the RCHs hardly differs from that of the soil outside of the charcoal hearth sites. The soil colors and magnetic susceptibility values strongly suggest that the RCH substrates and the underlying topsoil were affected by thermally induced transformation of iron (hydr-)oxides. Although the charring procedure normally requires ~2 weeks, the heating effect only reaches to a maximum depth of 8 cm into the buried soil below the charcoal hearths. The presence of reddish soil and an abrupt increase in magnetic susceptibility in the upper 2 cm of the soil below the charcoal hearths indicate the heat-induced transformation of iron (hydr-)oxides into maghemite. Brighter soil color and an increase in soil organic matter (SOM) in the lower parts of the buried topsoil demonstrate the combustion of SOM up to 5 cm depth below the RCH. According to the German Guidelines for Soil Mapping, the soils in the RCHs are classified as Regosols above Braunerde [WRB: Spolic Technosols (Arenic)]. However, because the anthropogenic features of these soil sediments are disregarded in the German Guidelines for Soil Mapping, we suggest adapting the "M" horizon to permit a jM horizon.

In the Litchfield Hills in west Connecticut, RCH sites are located mainly on slopes and therefore differ in their architecture from lowland sites found in Europe. One of the striking characteristics of a RCH site regardless of its architecture is the enrichment of the soil with charcoal in varying particle sizes. In this study, we use chemical digestion coupled with a PLSR-model to quantify organic carbon and pyrogenic carbon in RCH substrate by MIR-DRIFT measurements. Furthermore, we analyse the quality of carbon compounds by MIR-DRIFT measurements on multiple grain size fractions to assess the post-burn enrichment of soil organic matter. Preliminary results show a markedly increase in organic and pyrogenic carbon in RCH substrates in relation to the natural forest soil. Also, our first results suggest that the enrichment of organic carbon is favoured on RCHsites. However, the causality between the enrichment of soil organic matter and site features remains open.

The history and technique of charcoal production are described to clarify legacy effects. Applying a recently presented morpho-genetic catalogue is useful for classified mapping of RCH findings.

RCH soil properties feature dark charcoal-rich technogenic substrate layers classified as Auh horizons according to the World Reference Base with significantly increased C contents. These Auh horizons can also exhibit specific physical and chemical properties, such as relatively low bulk density, high porosity, high plant available water content, low thermal conductivity and differences in cation exchange capacity or nutrient status. However, relevant studies are rare, and thus, the effects may differ by study region. Regarding vegetation, there seem to be four main effects: changes in forest structure, species composition, recruitment pattern and productivity. The number of studies on this issue is, however, also very limited. Even fewer studies have examined the soil fauna in RCHs; thus, the reported effects cannot be used to draw general conclusions. Notably, RCH research has made considerable progress in the last five years, especially in the Light Detection and Ranging-based mapping of these small landforms and identification of RCH-specific soil properties, but ecological legacies are not well understood; thus, more interdisciplinary and integrative studies are needed.}, language = {en} } @inproceedings{RaabRaabSchneideretal., author = {Raab, Thomas and Raab, Alexandra and Schneider, Anna and Hirsch, Florian and Takla, Melanie and Nicolay, Alexander and Bonhage, Alexander and Bauriegel, Albrecht and R{\"o}sler, Horst}, title = {Landnutzungsgeschichte und historische Landschaftsentwicklung in der Niederlausitz - Neue Befunde und aktuelle Forschung}, series = {Jahrestagung Arbeitskreis Geoarch{\"a}ologie, T{\"u}bingen, 4.

During the time it operated, extensive transformations are supposed to have affected the landscape in the vicinity because of wood consumption and especially charcoal production. Digital datasets about forested areas for different timespans reconstructed from historical maps were made available. In combination with dendrochronological dating of charred trees, the spatiotemporal dimension of charcoal kilns was determined. Also, sites of former bog iron ore mining could be identified.

In 2017, the historic silver mine in Tarnowsky Gory was recognized as a UNESCO World Heritage Site. With the mining of galena (PbS), the region developed into one of the most important industrial centers in Central Europe in the 16th century. In addition to the underground galleries, the historical mining has left thousands of mining shafts as small relief forms, which have not been systematically investigated so far. Partly the mining shafts are associated with Relict Charcoal Hearths (RCH), another small form which is a result of charcoal production. In the Mala Panew River valley, north of Tarnowsky Gory, several tens of thousands of these RCH are found, which could be mapped by LiDAR in recent years. More detailed pedological investigations, which would allow a systematic comparison with other known RCH sites, are missing so far. Within the framework of a Polish-German cooperation project, we started in 2021 to investigate the mining shafts and the RCH in Tarnowsky Gory and in the Mala Panew River valley from a pedological-sedimentological point of view. At the RCH sites on the Mala Panew River, we focused on the following questions: How was the soil stratigraphy changed by the RCH construction? What are main processes of soil development before and after RCH construction? What was the role of the pits surrounding the RCH? How do the sites differ from the RCHs at Tarnowsky Gory especially with respect to soil properties and soil genesis? In Tarnowsky Gory, where a RCH was excavated directly next to a mining shaft, the following questions were in focus: How did the mining activity change soil distribution and soil properties? What are main processes of soil development on the different parts? What is the origin of the pit infill? What is the origin of the shaft rim deposits? Our work program included the construction of excavator trenches across the mining remains, construction, description and sampling of soil profiles along the trenches, schematic drawing of the soil stratigraphy, and laboratory analyses for the determination of texture, Munsell color, pH (CaCl2, H20), CaCO3 content, Ctotal \& Ntotal and total elements by FPXRF.

RCH sites are characterized by the admixture of charcoal fragments to the natural forest soil, constituting an anthropogenic addition of carbon. Dendrochronological dating of large charcoal pieces has identified RCH ages ranging from 1709 AD to 1823 AD for a subarea in the Tauer Forest, which allows for assessing century old effects of charcoal application on forest soils. We measured the geometry and soil organic matter (SOM) content of 20 RCH sites in a selected part of the forest. The results provide a basis for estimating RCH SOM stocks on a 40-ha forest plot with 120 RCH sites. We also assessed the accuracy of RCH mapping based on digital elevation models (DEMs) with results from a ground survey. Over 50 \% of sites were not detected by the DEM-based mapping. In the range of statistical uncertainties, RCHs add between 18 \% and 32 \% of SOM to the stock of the natural forest soil in the study area. This equals an additional 4.9 - 8.9 Mg of carbon per hectare of forest soil. These substantial amounts of SOM are so far not recognized by any survey or forest soil SOM inventories. Considering recent studies, which uncovered tens- and hundreds- of thousands of RCHs throughout Europe and the USA, we conclude that further knowledge of RCH SOM is important for quantifying anthropogenic SOM stocks on a global scale.}, language = {en} } @misc{RaabBonhageSchneideretal., author = {Raab, Alexandra and Bonhage, Alexander and Schneider, Anna and Raab, Thomas and R{\"o}sler, Horst and Heußner, Karl-Uwe and Hirsch, Florian}, title = {Spatial distribution of relict charcoal hearths in the former royal forest district Tauer (SE Brandenburg, Germany)}, series = {Quaternary International}, volume = {Vol. 511}, journal = {Quaternary International}, issn = {1040-6182}, doi = {10.1016/j.quaint.2017.07.022}, pages = {153 -- 165}, abstract = {Historical charcoal production has long been an unconsidered type of forest utilization in lowland areas. The archaeological discovery of a large charcoal burning area in the forefield of the active opencast lignite mine J€anschwalde in SE Brandenburg (North German Lowlands) has highlighted the need for multidisciplinary research in the study of the dimensions of historical charcoal burning. The charcoal produced in our study area, the former royal forest district Tauer, provided energy for the nearby Peitz ironworks during its operation from the mid-16th to the mid-19th century. Here, we aimed to record the amount, size and distribution of relict charcoal hearths (RCHs) to examine their context with respect to the ironworks and to better understand the potential impacts on late Quaternary landscape change. The applied methods combined archaeological research with shaded-relief mapping of RCHs. To evaluate the detection success of RCHs in the shaded-relief maps (SRMs), we compared the results with the results from specific archaeological surveys and conventional forest site mapping. Furthermore, we analyzed our dataset with descriptive, comparable and spatial statistics. Additionally, dendrochronological dating of charcoal fragments from selected RCHs was used to investigate the temporal relationships among the RCHs. Approximately 6000 circular RCHs were manually digitally identified in the SRMs of the 109-km2 evaluable area. However, ground truthing showed that the shaded-relief maps could not completely capture all RCHs in our study area due to local conditions. At the regional scale, two focus areas with high RCH site densities were found. Statistical analysis revealed that the diameters of the RCHs range widely from 4 to 30.5 m. Spatial statistics were applied to the RCH diameters to aggregate areas with larger or smaller RCHs. At the small scale, no systematic arrangement of RCHs was obvious in the SRMs. Dendrochronological dating of selected RCHs lying close together could not detect significant spatiotemporal relationships or patterns. The dating results also showed that some areas have been preferentially used for charcoal production for over 300 years. Due to the homogeneity of the physiogeographical location factors, we assume that these factors are not superficially responsible for site selection. Instead, economic location factors and contemporary regulations are more likely responsible for the distribution of RCHs.}, language = {en} } @misc{BonhageHirschRaabetal., author = {Bonhage, Alexander and Hirsch, Florian and Raab, Thomas and Schneider, Anna and Raab, Alexandra and Ouimet, William}, title = {Characteristics of small anthropogenic landforms resulting from historical charcoal production in western Connecticut, USA}, series = {Catena}, volume = {195}, journal = {Catena}, issn = {0341-8162}, doi = {10.1016/j.catena.2020.104896}, pages = {14}, language = {en} } @misc{HirschSchneiderBonhageetal., author = {Hirsch, Florian and Schneider, Anna and Bonhage, Alexander and Raab, Alexandra and Drohan, Patrick J. and Raab, Thomas}, title = {An initiative for a morphologic-genetic catalog of relict charcoal hearths from Central Europe}, series = {Geoarchaeology}, volume = {35}, journal = {Geoarchaeology}, number = {6}, issn = {1520-6548}, doi = {10.1002/gea.21799}, pages = {974 -- 983}, language = {en} } @misc{SchneiderHirschBonhageetal., author = {Schneider, Anna and Hirsch, Florian and Bonhage, Alexander and Raab, Alexandra and Raab, Thomas}, title = {The soil moisture regime of charcoal-enriched land use legacy sites}, series = {Geoderma}, volume = {366}, journal = {Geoderma}, issn = {0016-7061}, doi = {10.1016/j.geoderma.2020.114241}, pages = {15}, language = {en} } @misc{SchneiderBonhageHirschetal., author = {Schneider, Anna and Bonhage, Alexander and Hirsch, Florian and Raab, Alexandra and Raab, Thomas}, title = {Hot spots and hot zones of soil organic matter in forests as a legacy of historical charcoal production}, series = {Forest Ecology and Management}, volume = {504}, journal = {Forest Ecology and Management}, issn = {1872-7042}, doi = {10.1016/j.foreco.2021.119846}, abstract = {Human land use often leads to distinct modifications of soils within small, clearly delimited areas. Legacy effects of past land use are also abundant in recent forest areas, but are hardly considered in ecosystem assessment and soil mapping. The soils on relict charcoal hearths (RCHs) are a widespread example for such land use legacy soils in forests. Soils on RCHs differ clearly from surrounding forest soils in their stratigraphy and properties, and are most prominently characterized by a technogenic substrate layer with high contents of charcoal and thus soil organic matter (SOM). Although RCH soils can clearly contribute to the SOM stocks of forest soils, their relevance on the landscape scale has hardly been quantified. In this paper we analyze and discuss the distribution and effects of RCH soils across scales for forests in the state of Brandenburg, Germany, with a focus on SOM stocks. Our analysis is based on a large-scale mapping of RCHs from digital elevation models (DEMs), combined with a linear regression model of SOM stocks in RCH soils. The spatial distribution of RCH soils in the study region has a scale dependent heterogeneity. The large-scale variation in site densities is related to the concentration of charcoal production to specific forest areas while the small-scale variation is related to the irregular distribution of single RCHs within the charcoal production fields. Up to 1.5 \% of the surface are covered by RCH soils in the forest areas within the study region. The results also show that RCHs can significantly contribute to the SOM stocks of forests, even where they cover only a small fraction of the soil surface, with up to 18 \% additional SOM for forest areas. Because of the heterogeneous distribution of RCHs, the SOM stock additions depend on the scale of observation. Our results suggest that RCH SOM additions can be overestimated when sites in small areas (< 1 km²) are analyzed; and that characteristic spatial concentration patterns of RCHs are even observable when values are aggregated to large areas (25 km² and more). Aggregating effects to irregularly-sized forest administrative units resulted in maps that well represent the spatial distribution of RCH soils and SOM. The study highlights that considering land use legacy effects can be relevant for the results of soil mapping and inventories; and that prospecting and mapping land use legacies from DEMs can contribute to improving such approaches.}, language = {en} } @misc{BonhageEltaherRaabetal., author = {Bonhage, Alexander and Eltaher, Mahmoud and Raab, Thomas and Breuß, Michael and Raab, Alexandra and Schneider, Anna}, title = {A modified Mask region-based convolutional neural network approach for the automated detection of archaeological sites on high-resolution light detection and ranging-derived digital elevation models in the North German Lowland}, series = {Archaeological Prospection}, volume = {28}, journal = {Archaeological Prospection}, number = {2}, issn = {1099-0763}, doi = {10.1002/arp.1806}, pages = {177 -- 186}, language = {en} } @inproceedings{SchneiderRaabBonhageetal., author = {Schneider, Anna and Raab, Alexandra and Bonhage, Alexander and Hirsch, Florian and Raab, Thomas}, title = {Legacies of historic charcoal production in Brandenburg, Germany}, series = {Conference booklet, 5th International Landscape Archaeology Conference, 17th-20th September 2018 Newcastle and Durham, UK}, booktitle = {Conference booklet, 5th International Landscape Archaeology Conference, 17th-20th September 2018 Newcastle and Durham, UK}, pages = {S. 214}, language = {en} } @misc{RaabRaabBonhageetal., author = {Raab, Alexandra and Raab, Thomas and Bonhage, Alexander and Schneider, Anna and Verschoof-van der Vaart, Wouter and Bauriegel, Albrecht}, title = {Geomorphology of the Schwarze Elster Valley (Southwest Brandenburg, Germany) at the Bronze Age barrow cemetery Schweinert - Findings from the 2023 research campaign}, series = {DGGM Meeting 2023 Conference proceedings 04.-06.10.2023, RWTH Aachen}, journal = {DGGM Meeting 2023 Conference proceedings 04.-06.10.2023, RWTH Aachen}, pages = {S. 60}, language = {de} } @misc{RaabRaabBonhageetal., author = {Raab, Thomas and Raab, Alexandra and Bonhage, Alexander and Schneider, Anna and Drohan, Patrick J. and Wistuba, Małgorzata and Malik, Ireneusz and Verschoof-van der Vaart, Wouter}, title = {Small anthropogenic landforms from past land use - what have we (already) learned and what do we (still) want to know}, series = {DGGM Meeting 2023 Conference proceedings 04.-06.10.2023, RWTH Aachen}, journal = {DGGM Meeting 2023 Conference proceedings 04.-06.10.2023, RWTH Aachen}, pages = {S. 61}, language = {de} } @inproceedings{LuciusHuetterDietrichetal., author = {Lucius, Andreas and H{\"u}tter, Simon and Dietrich, Philipp and Schneider, Marc and Lehmann, Marius and Geyer, Thomas}, title = {Experimental and Numerical Investigation of Axial Fan Aeroacoustics at Disturbed Inflow Conditions}, series = {Fan 2018, International Conference on Fan Noise, Aerodynamics, Applications and Systems, Darmstadt 2018}, booktitle = {Fan 2018, International Conference on Fan Noise, Aerodynamics, Applications and Systems, Darmstadt 2018}, publisher = {CETIAT}, address = {Villeurbanne, France}, language = {en} } @misc{HirschSchneiderNicolayetal., author = {Hirsch, Florian and Schneider, Anna and Nicolay, Alexander and Blaszkiewicz, Miroslaw and Kordowski, Jarosław and Noryskiewicz, Agnieszka M. and Tyszkowski, Sebastian and Raab, Alexandra and Raab, Thomas}, title = {Late Quaternary landscape development at the margin of the Pomeranian phase (MIS 2) near Lake Wygonin (Northern Poland)}, series = {Catena}, volume = {124}, journal = {Catena}, issn = {0341-8162}, doi = {10.1016/j.catena.2014.08.018}, pages = {28 -- 44}, abstract = {In Central Europe, Late Quaternary landscapes experienced multiple phases of geomorphologic activity.

The pedostratigraphical findings from soil pits and drillings were extrapolated using ground-penetrating radar (GPR) and electric resistivity tomography (ERT). During the Pomeranian phase, glacial and fluvioglacial processes dominated the landscape near Lake Wygonin. At the end of the glacial period, periglacial processes became relevant and caused the formation of ventifacts and coversands containing coated sand grains. At approximately 15,290-14,800 cal yr BP, a small pond formed in a kettle hole (profile BWI2). The lacustrine sediments lack eolian sand components and therefore indicate the decline of eolian processes during that time. The increase of Juniperus and rock-rose (Helianthemum) in the pollen diagram is a prominent marker of the Younger Dryas. At the end of the Younger Dryas, a partial reshaping of the landscape is indicated by abundant charcoal fragments in disturbed lake sediments. No geomorphologic activity since the beginning of the Holocene is documented in the terrestrial and wetland archives. The anthropogenic impact is reflected in the pollen diagram by the occurrence of rye pollen grains (Secale cereale) and translocated soil sediments dated to 1560-1410 cal yr BP, proving agricultural use of the immediate vicinity. With the onset of land use, gully incision and the accumulation of colluvial fans reshaped the landscape locally. Since 540-460 cal yr BP, further gully incision in the steep forest tracks has been associated with the intensification of forestry.

Such relict charcoal hearths (RCH) exhibit a clearly altered soil stratigraphy, most prominently characterized by a technogenic substrate layer on the soil surface, and their soil physical properties can considerably differ from those of surrounding forest soils. The aim of our study is to characterize the soil water and temperature regime on RHC in a pre-industrial charcoal production area in Brandenburg, Germany, as compared with the surrounding sandy forest soils. Soil properties were analyzed in profiles on and around hearth sites and are monitored in a sensor transect equipped with soil moisture sensors and pF-meters. Results of soil sample analyses show differences in density and porosity between the RCH soils and surrounding forest soils, not only in the technogenic layer but also in the buried soil layers on hearth sites. The soil water characteristic curves determined in the laboratory indicate a modified pore size distribution and lower plant available water contents in the RCH soils. Preliminary results of the ongoing soil water monitoring, however, show increased soil wetness in the RCH soils, along with lower soil moisture tensions. Furthermore, the measurements show higher variations of soil temperature in RCH soils. The results affirm that the legacies of historic charcoal production can increase the spatial variability of soil physical properties and therefore also of ecological site conditions in forest areas.

The most prominent feature of the soils on RCHs is the anthropogenically modified 20-30 cm thick RCH substrate that buries the former forest soil. The RCH substrate is a quite heterogenous mixture of mineral and organic compounds which were modified through heat during charring. It is characterized by its black color resulting from charcoal fragments (from fine dust to decimetre size pieces), lower bulk density, and higher porosity. After their use, the charcoal production sites were abandoned and soon became overgrown. Soil formation could commence in this anthropogenically modified RCH substrate. During recently conducted field work on RCHs in the Tauer Forest we detected features of initial podzolisation (bleaching of quartz grains) within this RCH substrate. To further investigate initial processes of soil formation (acidification, podzolisation, accumulation of soil organic matter) on RCHs, two different RCH sites were selected in the Tauer Forest: one RCH site in the forest district Tannenwald and one RCH site in the forest district Kleinsee. The Tannenwald site (RCH no. 29958) is situated in the western part of the Tauer Forest. It is an inland dune area with a coniferous forest (Scots pine, Pinus sylvestris L.) plantation. The forest soils are Podzols and the soils on the RCHs are classified as Spolic Technosols. The dense undergrowth consists of mainly blueberry (Vaccinium L.). Dendrochronological ages (determination by K-U Heußner, DAI Berlin) of charcoal pieces proof, that the charcoal hearth was used after 1655. The Kleinsee site (RCH no. 29424) is situated in the eastern part of the Tauer Forest. The parent material is sand from glaciofluvial sediments of the Weichselian glaciation. The forest soils are Brunic Arenosols (Protospodic) and the soils on the RCHs are classified as Spolic Technosols (Arenic). The deciduous forest is dominated by sessile oak (Quercus petraea (Matt.) Liebl.). The undergrowth is only scarce with some ferns (sporadic), blueberry (Vaccinium L.), some shoots of rowan (Sorbus aucuparia L.) and some moss. There is no dendrochronological age available from the RCH, but RCHs nearby were dated from the 18th to the 19th centuries. At both sites, three soil monoliths were sampled on the RCH platform and three monoliths from the natural forest soil as reference soils. The soil monoliths were sampled continuously in 3 cm vertical spacings. Following lab analyses were carried out: pH (CaCl2), pH (H2O), total carbon (TC), total nitrogen (TN), CECeff and total concentrations of selected elements. Analyses of pedogenic Fe are in progress. First results of these study will be presented and discussed.}, language = {en} } @book{RaabRaabBonhageetal., author = {Raab, Alexandra and Raab, Thomas and Bonhage, Alexander and Schneider, Anna and Hirsch, Florian and Aghte, Markus and Pommerenke, Alf}, title = {Historische K{\"o}hlerei in S{\"u}dbrandenburg - Begleitband zum K{\"o}hlerpfad Waldschule Kleinsee}, editor = {Raab, Thomas}, publisher = {Brandenburgische Technische Universit{\"a}t Cottbus - Senftenberg, Fachgebiet Geopedologie und Landschaftsentwicklung}, address = {Cottbus}, issn = {2196-4122}, doi = {10.26127/BTUOpen-5488}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:co1-opus4-54883}, pages = {68}, language = {de} } @misc{UchinoRaabBonhageetal., author = {Uchino, Kazuki and Raab, Alexandra and Bonhage, Alexander and Schneider, Anna and Raab, Thomas and Wechler, Klaus-Peter and Bauriegel, Albrecht}, title = {Spatial heterogeneity of buried and recent soils in a drift sand area in North-Eastern Germany}, series = {EGU General Assembly 2022, Vienna, Austria, 23-27 May 2022}, journal = {EGU General Assembly 2022, Vienna, Austria, 23-27 May 2022}, doi = {10.5194/egusphere-egu22-2354}, abstract = {In the North European Lowland, on the sandy deposits of the Weichselian glaciation, soils developed during periods of landscape stability are often conserved under windblown sand. However, small-scale changes of sediments and other soil forming factors can result in high spatial variation of soil properties in these landscapes; and relocation of soil material by geomorphic processes further increases the spatial heterogeneity of the soil landscape. These spatial variations in soil properties and conservation need to be considered in order to correctly decipher and interpret the buried soils as records of past environmental conditions. In the forefield of the open-cast mine Cottbus-Nord, archaeological excavations in a dune and drift sand area revealed widespread buried soils of different characteristics. The densely spaced excavation trenches give exceptionally good insights into the pedosphere, allow for reconstructing the distribution of fossil and recent soils in a high spatial resolution, and offer good opportunities to improve the understanding of spatial and temporal patterns of soil formation. Remains of postpleistocene hunter-gatherer campsites were documented in archaeological excavations and found to be associated with a buried soil horizon. We recorded the stratigraphy of soil profiles along more than 15 trenches within an area of about 20 ha, and additionally described the position of buried soils from GPR surveys and microdrone photogrammetry. In a recently opened, 455 m long trench, all characteristic soils and sediments of the study region could be observed and stratigraphically connected. Within this trench, four profiles were identified for further research. Each profile was classified and described according to WRB and German Guidelines for Soil Mapping; and was sampled and investigated through laboratory analyses including determination of organic matter, total carbon and nitrogen contents, soil colour identification, texture analysis, magnetic susceptibility measurement, metal content analysis using X-ray fluorescence analyzer and pH measurement. The compaction and cementation of soil horizons was assessed in situ with a pocket penetrometer. Results show a small-scale mosaic of soils developed on fluvio-aeolian, limnic and aeolian sediments, high spatial variations in pedogenesis due to varying groundwater influence and intensity of horizontal and vertical leachate transport, and high variations in the erosion or conservation of fossil soils. The soil and sediment stratigraphy reflects several phases of landscape development: i) the formation of a Late Pleistocene soil on fluvio-aeolian deposits, ii) a fossilization by aeolian sands, iii) a stability phase with intensive podsolization and peat formation, and iv) a land use-induced aeolian remobilization of the sands.}, language = {en} } @misc{AlJobayerBlossPorschetal., author = {Al Jobayer, Md Adif and Bloß, Katharina and Porsch, Christopher and Maaten, Ernst van der and Maaten-Theunissen, Marieke van der and Bonhage, Alexander and Raab, Alexandra and Schneider, Anna and Raab, Thomas}, title = {Drought sensitivity of Pinus sylvestris L. on century old charcoal rich Technosols in the North-German Lowland}, series = {EGU General Assembly 2022, Vienna, Austria, 23-27 May 2022}, journal = {EGU General Assembly 2022, Vienna, Austria, 23-27 May 2022}, doi = {10.5194/egusphere-egu22-7978}, abstract = {Soils on relict charcoal hearths (RCHs), i.e. aged charcoal rich Technosols, feature documented legacy effects regarding their physical and chemical soil properties. These forest soils result from the pre-/early-industrial production of charcoal in upright standing hearths. Today, RCHs are found in forested areas as circular microrelief structures with average diameters of about 10 meters that contain technogenic soil horizons of about 20 cm thickness. RCH soils are most distinctly characterized by their large content of pyrogenic soil organic matter and consequently increased total carbon contents. The resulting changes in the soils' cation exchange capacity, soil acidity, total nitrogen contents and total element stocks are often significant. Furthermore, changes in soil physical properties like a lower bulk density and a higher porosity result in changed soil-water- and temperature regimes. Combined, these effects potentially result in unique soil microhabitats that are restricted to relatively small, clearly defined areas in many forest ecosystems. Recent studies on RCH soils increasingly focus on potential changes in microbiological and vegetational composition and abundances and report diverse effects. Here, we study the effects of century old charcoal rich Technosols on the drought sensitivity of Scots pine (Pinus sylvestris L.) on three RCH sites located in Lower Lusatia, Saxony (Germany). Through dendrochronologial analysis of increment cores and historical climate data, we study climate-growth relationships for trees on RCH soils and reference forest soils for two periods (AD 1963-1992 \& AD 1990-2019). Furthermore, we determine pointer years and components of resilience to quantify the trees' reaction to extreme weather conditions. This analysis was accompanied by soil sampling and analysis on the RCH sites and adjacent reference forest soils.

Geomorphological processes in (pre)history can have resulted in a modification of the local relief around archaeological sites, especially in areas that are prone to sediment erosion and relocation, so that models of past surfaces are necessary for a correct interpretation of archaeological survey results. In this study, we combined terrestrial survey and remote sensing methods to reconstruct the palaeorelief around two archaeological excavation sites in an inland dune area in southern Brandenburg, Germany. Remains from two Mesolithic hunter-gatherer camps were documented in archaeological excavations and found to be associated with a buried soil horizon. To gather information on the relief of the buried soil surface, we used a combination of sedimentological and pedological profile description of archaeological survey trenches and geophysical prospection with Ground-Penetrating Radar; supplemented by microdrone photography and photogrammetry, GPS surveys and analysis of LIDAR-based elevation models. A digital elevation model of the buried surface was created by combining point data from these sources. The buried surface morphology and the position of the archeological remains within the reconstructed landscape were analyzed in GIS. The comparison of the generated paleosurface model with the recent surface elevation model shows that sand remobilization resulted in a considerable reshaping of the relief. Analysis of the buried surface model further shows that the relief position of the two archaeological sites in the study area was considerably more prominent in relation to the corresponding buried soil surface than in relation to the recent surface morphology.

Information on theses parameters was gathered in an archive and literature study and from historical and recent maps. Areas with a high probability of kiln site occurrence were then determined using a simple binary additive model. In the last step, shaded-relief maps (SRMs) were visually checked for clearly visible kiln sites and soil properties were analysed in the determined areas. In total, eight areas with a high probability of kiln site occurrence are identified for the state of Brandenburg. By visual interpretation of SRMs, high kiln site densities in these areas are confirmed. The analysis of soil maps shows that kiln fields are predominantly located on sandy soils with a low yield potential.

Ausfallstatistiken der LEAG1 lassen jedoch den Schluss zu, dass es durch die Bearbeitung der Mantelfl{\"a}che (i.d.R. {\"U}berdrehen) ebenfalls zu einer Steigerung der Lebensdauer der Tragrollen kommt. Um das Sch{\"a}digungsverhalten bei unterschiedlichen Kraftanregungen zu untersuchen, wurde ein Verschleißpr{\"u}fstand entwickelt, konstruiert und gebaut.

We aimed to determine which saccadic and vestibulo-ocular reflex parameters best predict the presence of symptoms in unilateral vestibular hypofunction in order to better understand vestibular compensation and its implications for rehabilitation therapy. Methods: Video head impulse test data were analyzed from a subpopulation of 23 symptomatic and 10 currently symptom-free participants with unilateral vestibular hypofunction, embedded in the KORA (Cooperative Health Research in the Region of Augsburg) FF4 study, the second follow-up of the KORA S4 population-based health survey (2,279 participants). Results: A higher number of catch-up saccades, a higher percentage of covert saccades, and a larger retinal error at 200 ms after the onset of the head impulse were associated with relevant symptoms in participants with unilateral vestibular hypofunction (p = 0.028, p = 0.046, and p = 0.038, respectively). After stepwise selection, the number of catch-up saccades and retinal error at 200 ms remained in the final logistic regression model, which was significantly better than a null model (p = 0.014). Age, gender, saccade amplitude, saccade latency, and VOR gain were not predictive of the presence of symptoms. Conclusion: The accuracy of saccadic compensation seems to be crucial for the presence of symptoms in unilateral vestibular hypofunction, highlighting the role of specific gaze stabilization exercises in rehabilitation. Early saccades, mainly triggered by the vestibular system, do not seem to compensate accurately enough, resulting in a relevant retinal error and the need for more as well as more accurate catch-up saccades, probably triggered by the visual system.}, language = {en} } @misc{SchneiderDonovanHirschetal., author = {Schneider, Anna and Donovan, Sara and Hirsch, Florian and Bonhage, Alexander and Raab, Alexandra and Raab, Thomas}, title = {Der Einfluss von Relikten der historischen K{\"o}hlerei auf Bodentemperatur und -w{\"a}rmeleitf{\"a}higkeit}, series = {Abstract-Band, Jahrestagung der Bodenkundlichen Gesellschaft der Schweizund der Deutschen Bodenkundlichen GesellschaftBern, 24.-29.

Ages of about 250 years proven by dendrochronological dating of larger charcoal pieces on RCHs allow for assessing long-term effects of biochar application on forest soils. In this study, we measured the geometry and SOM content of 20 RCH sites in a selected part of the forest district. The results are the basis for a projection of RCH SOM stocks on a 40 ha forest plot with 120 RCH sites. In the range of statistical uncertainties it is shown that RCHs add between 13 \% and 32 \% of SOM to the SOM stock of the natural forest soil in the studied plot. These substantial amounts of SOM are so far not recognized by any soil survey or forest soil inventories of SOM and SOC stocks. In light of an increasing amount of studies that detect RCH sites in forests of Europe and the USA in the range of tens-and even hundreds of thousands, the question has to be asked how to address this legacy effect in ongoing scientific discussions about soil carbon stocks, carbon sequestration and the long-term effects of biochar application into soils.}, language = {de} } @inproceedings{HirschNicolaySchneideretal., author = {Hirsch, Florian and Nicolay, Alexander and Schneider, Anna and Błaszkiewicz, Mirosław and Kordowski, Jarosław and Noryskiewicz, Agnieszka M. and Tyszkowski, Sebastian and Raab, Alexandra and Raab, Thomas}, title = {Sp{\"a}tquart{\"a}re Landschaftsentwicklung seit der Pommerschen Phase in Wygonin (Nordpolen)}, series = {Jahrestagung des AK Geomorphologie in Kiel 2014}, booktitle = {Jahrestagung des AK Geomorphologie in Kiel 2014}, editor = {Bork, Hans-Rudolf and Dreibrodt, Stefan and Duttmann, Rainer and Unkel, Ingmar}, publisher = {Christian-Albrechts-Universit{\"a}t}, address = {Kiel}, pages = {S. 66}, language = {de} } @misc{SchneiderFritschMagisteretal., author = {Schneider, Robert and Fritsch, Tim and Magister, Jan and Rieder, Thomas and Hernschier, Stephan and Simon, Sylvio}, title = {Die Akustische Kamera zur gezielten L{\"a}rmminderung und zustandsbezogenen Instandhaltung von Tagebau-Großger{\"a}ten}, series = {10.

Multiple reshaping since the Late Glacial considerably changed the landscape up to and including especially historic times.

Ongoing archaeological rescue excavations in the pre-field of the open-cast mine Cottbus-Nord (northeastern Germany) with dense excavation trenches in an about 10 ha dune and drift sand area reveal multilayered sediment sequences with fossilized soils and sediments from the Late Pleistocene to the Late Holocene. Archaeological findings ranging from Mesolithic flint stones to an about 200 year old ceramics in eolian sediments covering plow horizons and wheel tracks suggest that eolian relocation of sandy material was intensive about 200 years ago. Still unpublished OSL dating underline the intense eolian activity. Recent studies showed that between the 15Th to the 19Th century an iron smelter 5 km to the west of our study site was supplied with charcoal, which was produced in a forest 5 km east to our study site. Our current findings about Late Holocene eolian activity raise the question if this eolian reshaping of the landscape is connected with the operation of the iron smelter either directly by transport or bog iron ore winning or indirectly by population pressure caused by the prospering iron smelter.

Da die Abbaugebiete immer weiter in besiedelte Gegenden vordringen und die Vorgaben im Umweltschutz sich versch{\"a}rfen, ist der Betreiber in zunehmendem Maße bestrebt, unter anderem die Ger{\"a}uschemissionen der Tagebaugroßger{\"a}te zu senken. Da sich speziell Gurtf{\"o}rderanlagen im Bereich des Vorschnitts {\"u}ber große Entfernungen erstrecken und an den R{\"a}ndern der Tagebaue verlaufen, tragen diese zu einem großen Teil zur Ger{\"a}uschemission bei. Tragrollen sind oft zu Tausenden in den F{\"o}rderanlagen verbaut und bei der akustischen Wirkung von entscheidender Bedeutung. Um eine Gesundheitsgef{\"a}hrdung f{\"u}r die besch{\"a}ftigten Mitarbeiter durch L{\"a}rm zu vermeiden und die Auswirkungen auf angrenzende Siedlungen auf ein Mindestmaß zu begrenzen, existieren gesetzliche Vorschriften und Richtlinien. Die Gesetze und Verordnungen zum Umweltschutz und Arbeitsschutz sollen eine Reduzierung der L{\"a}rmimmissionen erreichen. Laut den Immissionsrichtwerten1 der Technischen Anleitung zum Schutz gegen L{\"a}rm (TA L{\"a}rm) darf nachts in Kerngebieten, Dorf- und Mischgebieten der Beurteilungspegel von 45 dB(A) nicht {\"u}berschritten werden, in reinen Wohngebieten liegt die Grenze sogar bei 35 dB(A). Zum Vergleich: Eine leise Unterhaltung oder leise Musik wird mit einem Schalldruckpegel von 40 dB(A) angegeben. Der durch den Betrieb der Gurtf{\"o}rderanlagen entstehende meterbezogene Schallleistungspegel LW betr{\"a}gt im Durchschnitt etwa 80 bis 100 dB(A). Durch Reduktion der Schallemission k{\"o}nnten die Planungen der Streckenverl{\"a}ufe optimiert werden, was zu wirtschaftlichen Einsparungen f{\"u}hrt. Weiterhin ist, wenn die f{\"u}r Tagebauanlagen zu beachtenden Richtwerte eingehalten werden, auch die Genehmigung f{\"u}r die Einrichtung und den Betrieb solcher Anlagen einfacher abzusichern. Um genaue Kenntnisse {\"u}ber die Schallemission von Tragrollen zu erlangen, wurde in Zusammenarbeit der ehemaligen VEM AG (jetzt LEAG) und der ehemaligen Hochschule Lausitz (jetzt BTU Cottbus-Senftenberg) ein Tragrollenpr{\"u}fstand entwickelt. Im Rahmen einer Baugruppenpr{\"u}fung auf diesem Pr{\"u}fstand werden akustische und mechanische Kenngr{\"o}ßen von Tragrollen untersucht. Bestandteile dieser Untersuchungen sind: - Hochfahrpr{\"u}fl{\"a}ufe - Dabei wird eine Tragrolle unter Pr{\"u}flast auf eine Umfangsgeschwindigkeit von 10 m/s beschleunigt und der Schalldruckpegel aufgezeichnet. Dies erm{\"o}glicht die Berechnung der Schallemission in Abh{\"a}ngigkeit von der Umfangsgeschwindigkeit. - Ermittlung des Abklingverhaltens - Durch Anschlagversuche wird das Eigenschwing- und D{\"a}mpfungsverhalten einer Tragrolle erfasst. - Erfassung der Tragrollengeometrie - Die pr{\"a}zise Beschreibung der Geometrie des Tragrollenmantels erm{\"o}glicht R{\"u}ckschl{\"u}sse auf m{\"o}gliche Anregungsursachen.}, language = {de} } @misc{RiederSchneiderHernschieretal., author = {Rieder, Thomas and Schneider, Robert and Hernschier, Stephan and Magister, Jan and Fritsch, Tim and T{\"a}schner, Dirk and Simon, Sylvio}, title = {Anbackungen - Untersuchungen zur Wirkung der Unwucht auf die Schallemission von Tragrollen an Gurtf{\"o}rderanlagen}, series = {24.

Dazu treibt eine Walze die {\"u}ber Gummid{\"a}mpfer eingespannte Pr{\"u}frolle an. An der Kontaktzone werden Belastungen von etwa 3,5 kN eingestellt. Die gepr{\"u}ften Unwuchtpaare liegen in den beiden Radialebenen (Seitendeckel) gegen{\"u}ber sowie um 180 Grad versetzt. Stufenweise wird mit Massest{\"u}cken die Unwucht erh{\"o}ht sowie weiterf{\"u}hrend erst phasengleich, dann erg{\"a}nzend um 180 Grad versetzt Klebestreifen auf dem Tragrollenmantel angebracht. Die Klebestreifen simulieren reproduzierbar Anbackungen, welche sich gegen{\"u}berliegend hinsichtlich ihrer Unwuchtmasse ausgleichen. Jeweils wird der sich einstellende Istzustand von Restunwuchtmasse und Schallleistungspegel ermittelt. Nach den Literaturangaben ist eine Erh{\"o}hung der Schallleistung mit steigender Unwucht und bei Anbackungen zu erwarten. Im Ergebnis zeigen Anbackungen eine hohe Wirkung auf die Ger{\"a}uschemission von Tragrollen, was den Schluss nahelegt, dass kein Zusammenhang zwischen Unwucht und Ger{\"a}uschemission besteht. Mit der weiterf{\"u}hrenden Untersuchung zur Pr{\"u}fung der akustischen Wirkung durch zus{\"a}tzliche Unwuchtmassen an einer Tragrolle war keine Erh{\"o}hung der Schallemission am Tragrollenpr{\"u}fstand nachzuweisen. Daf{\"u}r wurde gegen{\"u}ber der ersten Untersuchung (2018) bei der Umfangsgeschwindigkeit 7,5 m/s die dabei {\"u}berschrittene G{\"u}testufe 100 auf die G{\"u}testufe 250 gesteigert. Die Untersuchungen erfolgten mit unterschiedlichen l{\"a}rmgeminderten Tragrollen gleichen Typs, jedoch unterschiedlicher Ausf{\"u}hrungsform. Dabei war eine Tragrolle (0611) mit einer Innend{\"a}mpfung versehen und die andere Rolle (0609) ohne D{\"a}mpfungsmaterial. Im Zusammenhang mit den durchgef{\"u}hrten Versuchen folgt daraus, dass die Eigend{\"a}mpfung einer Tragrolle die Ergebnisse nicht beeinflusst. Die Erg{\"a}nzung des Unwuchtversuches mit den Klebestreifen zeigte einen direkten Zusammenhang zwischen geometriebedingter Anregung (Kreisformabweichung) und Schallemission. Die Eigenmasse der Klebestreifen ist klein gegen{\"u}ber den an den Seitendeckel angebrachten Unwuchtmassen. Diese Eigenmassen der Klebestreifen heben sich bei den Versuchen mit zwei Klebestreifen, die 180° auf dem Tragrollenmantel gegen{\"u}berliegend angebracht wurden, gegenseitig auf. Die Anregung zur Schallabstrahlung erfolgte {\"u}ber die Kreisformabweichung, was mit Hilfe der Verdopplung der Anregung und der daraus resultierenden Pegelerh{\"o}hung von 3 dB nachzuweisen war. Daraus folgt, dass die F{\"o}rdergutanbackungen an Tragrollen im Tagebau nicht durch die entstandene Unwucht, sondern nahezu ausschließlich durch die Geometriever{\"a}nderung auf dem Tragrollenmantel die Ger{\"a}uschemission erh{\"o}hen. Aus den Untersuchungen heraus bleibt die These zul{\"a}ssig, dass bisher kein kausaler Zusammenhang zwischen Unwucht und Ger{\"a}uschemission bei Tragrollen f{\"u}r Gurtf{\"o}rderanlagen nachzuweisen ist.

Soils of such lynchet systems feature distinctly modified stratigraphy and properties and thereby constitute a memory of past land use. At the same time, the legacies of past agriculture affect recent forest ecosystems. High-resolution digital elevation models (DEMs) allow to identify lynchets over large areas and open up new opportunities to study the spatial distribution patterns and soils of FFS. Within our research on different land use legacy features in forest areas, we study FFS in Northeastern Bavaria (Germany) in a geopedological approach, combining large-scale mapping and spatial analysis with the description and analysis of soil properties for specific sites. Lynchet areas (and other remnants of pre-industrial FFS) in recent forests were mapped from LIDAR DEMs for an area of 2045 km2 (972 km2 forest area). The mapping results show more than 100 km2 of abandoned field systems within the study area, mostly appearing as lynchet systems. Their spatial distribution patterns differ within the study area, mainly depending on parent material and landform. In the limestone region of the Franconian Jura, FFS occur spatially dispersed, often as considerably small, irregularly shaped parcels, presumably reflecting proceeding abandonment of less productive and accessible fields with intensification of agriculture. In contrast, FFS in the Bohemian Massif in the eastern part of our study area were often found in compounds of many regularly shaped parcels, frequently associated with deserted settlement areas. Soil stratigraphy and properties were studied for FFS and reference positions (forest areas with no indications of former agricultural use) in six study sites, combining detailed characterization of principal soil profiles and an assessment of spatial variations of soil properties in a near-surface sampling approach. First results show that FFS soils are characterized by truncated profiles over most parts of the treads and accumulation of colluvium confined to relatively small areas upslope of lynchet risers. The depth of soil profile truncation and height of lynchet risers differ, mainly related to slope and erodibility of the initial soils. Stratigraphy of the lynchet soils indicates a gradually proceeding formation. Carbon and nitrogen contents were found to differ between FFS and reference soils and to be more homogeneous within the FFS. Carbon contents were mainly lower in the FFS, while both lower and higher nitrogen contents were observed for FFS soils, presumably related to different duration and intensity of agricultural use. Overall, the results show that the legacy effects of past agriculture affect large fractions of recent forest areas, and can be of different quality depending on lithology of the soils' parent material and land use history.}, language = {en} } @article{WoldtGjardyHildebrandtetal., author = {Woldt, Thomas and Gjardy, Georg and Hildebrandt, Sven and Gr{\"u}newald, Holger and Stock, Oliver and Schneider, Bernd Uwe}, title = {Systemintegration dezentraler Energieandlungsanlagen unter besonderer Ber{\"u}cksichtigung regenerativer Energietr{\"a}ger}, series = {Forum der Forschung}, volume = {10}, journal = {Forum der Forschung}, number = {19}, issn = {0947-6989}, pages = {69 -- 74}, language = {de} } @misc{SchneiderBonhageRaabetal., author = {Schneider, Anna and Bonhage, Alexander and Raab, Alexandra and Raab, Thomas}, title = {Spatial and temporal variability of soil moisture in land-use legacy forest soils in Brandenburg, Germany}, series = {EGU General Assembly 2022, Vienna, Austria, 23-27 May 2022}, journal = {EGU General Assembly 2022, Vienna, Austria, 23-27 May 2022}, doi = {10.5194/egusphere-egu22-2182}, abstract = {Soil physical properties can show high heterogeneity in forest soils, implying a high spatial variability of soil moisture and plant water availability. Legacy effects of past land use, resulting in a small-scale mosaic of anthropogenically modified and unmodified soils in forest areas, further increase this spatial heterogeneity. The soils associated with relict charcoal hearths (RCH), most prominently characterized by a technogenic layer rich in charcoal fragments, are a widespread example for such land use legacy soils in forest areas. The objective of our study was to characterize the soil moisture regime of forest soils and RCH soils on sandy substrates in the northeastern German lowlands; and in particular to assess the long-term effect of the prolonged summer drought period in 2018 on spatial and temporal variability of soil moisture. We monitored matric potentials, soil water contents and soil temperature from June 2018 in forest soils in the Tauersche Forst (Brandenburg, Germany). Three soil profiles (one reference forest soil profile and two characteristic RCH soil profiles) were instrumented, sampled for laboratory analyses of bulk density, pore size distribution, saturated hydraulic conductivity, and persistence of water repellency; and root density distribution in the profiles was recorded. The soils in all profiles show low porosity and plant available water contents. On RCH soils, overall porosity is clearly higher compared with the reference soils, mainly related to larger volumes of coarse and fine pores. Soil moisture monitoring shows very high spatial and temporal variability of the recorded data after the prolonged dry period in 2018, with gradual rewetting over the winter periods and only short-term fluctuations of soil moisture in reaction to high-intensity precipitation events in the summer periods. The comparison of in-situ and laboratory-based water retention data shows strong hysteresis effects during the rewetting, with increasingly clear reactions of soil water contents to precipitation events over the years following the dry period, especially in the charcoal-rich substrates. The differences in soil moisture between the dry and the wetter periods were clearly higher in the RCH soils, which, compared with the reference soils, showed higher water contents under wet conditions and lower water contents under dry conditions.

We aimed to compare the diagnostic accuracy of vHIT metrics regarding the vestibulo-ocular reflex gain and the corrective saccades in detecting vestibular strokes. Methods: Prospective cross-sectional study (convenience sample) of patients presenting with acute vestibular syndrome in the emergency department of a tertiary referral centre between February 2015 and May 2020. We screened 1677 patients and enrolled 76 patients fulfilling the inclusion criteria of acute vestibular syndrome. All patients underwent video head impulse test with automated and manual data analysis. A delayed MRI served as a gold standard for vestibular stroke confirmation. Results: Out of 76 patients, 52 were diagnosed with acute unilateral vestibulopathy and 24 with vestibular strokes. The overall accuracy of detecting stroke with an automated vestibulo-ocular reflex gain was 86.8\%, compared to 77.6\% for cumulative saccade amplitude and automatic saccade mean peak velocity measured by an expert and 71\% for cumulative saccade amplitude and saccade mean peak velocity measured automatically. Gain misclassified 13.1\% of the patients as false positive or false negative, manual cumulative saccade amplitude and saccade mean peak velocity 22.3\%, and automated cumulative saccade amplitude and saccade mean peak velocity 28.9\% respectively. Conclusions: We found a better accuracy of video head impulse test for the diagnosis of vestibular strokes when using the vestibulo-ocular reflex gain than using saccade metrics. Nevertheless, saccades provide an additional and important information for video head impulse test evaluation. The automated saccade detection algorithm is not yet perfect compared to expert analysis, but it may become a valuable tool for future non-expert video head impulse test evaluations.}, language = {en} } @misc{BrandtGlasauerSchneider, author = {Brandt, Thomas and Glasauer, Stefan and Schneider, Erich}, title = {Aufnahmevorrichtung f{\"u}r die kopfgest{\"u}tzte Bilderfassung und Verfahren zur Steuerung der Aufnahmevorrichtung}, language = {de} } @misc{SchoeberlPradhanIrvingetal., author = {Sch{\"o}berl, Florian and Pradhan, Cauchy and Irving, Stephanie and Buerger, Katharina and Xiong, Guoming and Kugler, G{\"u}nter and Kohlbecher, Stefan and Engmann, Julia and Werner, Philipp and Brendel, Matthias and Schneider, Erich and Perneczky, Robert and Jahn, Klaus and Foug{\`e}re, Christian la and Bartenstein, Peter and Brandt, Thomas and Dietrich, Marianne and Zwergal, Andreas}, title = {Real-space navigation testing differentiates between amyloid-positive and -negative aMCI}, series = {Neurology : official journal of the American Academy of Neurology}, volume = {94}, journal = {Neurology : official journal of the American Academy of Neurology}, number = {8}, issn = {1526-632X}, doi = {10.1212/WNL.0000000000008758}, pages = {e861 -- e873}, language = {en} } @misc{KallaSpiegelClaassenetal., author = {Kalla, Roger and Spiegel, Rainer and Claassen, Jens and Bardins, Stanislav and Hahn, Ales and Schneider, Erich and Lehrer, Nicole and Glasauer, Stefan and Brandt, Thomas and Strupp, Michael}, title = {Comparison of 10-mg doses of 4-aminopyridine and 3,4-diaminopyridine for the treatment of downbeat nystagmus}, series = {Journal of neuro-ophthalmology}, volume = {32}, journal = {Journal of neuro-ophthalmology}, number = {2}, issn = {1536-5166}, doi = {10.1097/WNO.0b013e3182258086}, pages = {320 -- 325}, language = {en} } @misc{SchulzSchneiderFritzetal., author = {Schulz, Christian M. and Schneider, Erich and Fritz, L. and Vockeroth, Johannes and Hapfelmeier, Alexander and Brandt, Thomas}, title = {Visual attention of anaesthetists during simulated critical incidents}, series = {British Journal of Anaesthesia}, volume = {106}, journal = {British Journal of Anaesthesia}, number = {6}, issn = {1471-6771}, doi = {10.1093/bja/aer087}, pages = {807 -- 813}, language = {en} } @inproceedings{ReifSchneiderSchmidetal., author = {Reif, J{\"u}rgen and Schneider, Thomas and Schmid, Reiner P. and Wolfframm, Dirk}, title = {Nonlinear optical characterization of the surface of silicon wafers: In-situ detection of external stress}, series = {Laser Applications in Microelectronics and Optoelectronic Manufacturing V, 24 - 26 January 2000, San Jose, USA}, booktitle = {Laser Applications in Microelectronics and Optoelectronic Manufacturing V, 24 - 26 January 2000, San Jose, USA}, editor = {Helvajian, Henry}, publisher = {SPIE}, address = {Bellingham, Wash.}, isbn = {0-8194-3550-3}, language = {en} } @misc{MayerHerrKleinetal., author = {Mayer, Alena and Herr, Raphael M. and Klein, Thomas and Wiedemann, Eva and Diehl, Katharina and Hoffmann, Stephanie and Blume, Miriam and Jepsen, Dennis and Sundmacher, Leonie and Andreas, Marike and Schneider, Sven}, title = {Socio-economic inequalities in body mass index among preschool children: do sports programs in early childhood education and care centers make a difference?}, series = {Frontiers in Public Health}, volume = {Vol. 11}, journal = {Frontiers in Public Health}, issn = {2296-2565}, doi = {10.3389/fpubh.2023.1079871}, abstract = {Background: Overweight in childhood is considered to be one of the most serious public health challenges. Many studies have investigated individual-level determinants of children's body mass index (BMI), yet studies exploring determinants at the meso-level are sparse. The aim of our study was to examine how a sports focus at early childhood education and care (ECEC) centers moderates the effect of parental socio-economic position (SEP) on children's BMI. Methods: We used data from the German National Educational Panel Study and included 1,891 children (955 boys and 936 girls) from 224 ECEC centers in our analysis. Linear multilevel regressions were used to estimate the main effects of family SEP and the ECEC center sports focus, as well as their interaction, on children's BMI. All analyses were stratified by sex and adjusted for age, migration background, number of siblings, and employment status of parents. Results: Our analysis confirmed the wellknown health inequalities in childhood overweight with a social gradient toward a higher BMI for children from lower SEP families. An interactive effect between family SEP and ECEC center sports focus was found. Boys with low family SEP not attending a sports-focused ECEC center had the highest BMI among all boys. In contrast, boys with low family SEP attending a sports-focused ECEC center had the lowest BMI. For girls, no association regarding ECEC center focus or interactive effects emerged. Girls with a high SEP had the lowest BMI, independent of the ECEC center focus. Conclusion: We provided evidence for the gender-specific relevance of sports-focused ECEC centers for the prevention of overweight. Especially boys from low SEP families benefited from a sports focus, whereas for girls the family's SEP was more relevant. As a consequence, gender differences in determinants for BMI at different levels and their interaction should be considered in further research and preventive measures. Our research indicates that ECEC centers may decrease health inequalities by providing opportunities for physical activity.}, language = {en} } @misc{KuglerHuppertSchneideretal., author = {Kugler, G{\"u}nter and Huppert, Doreen and Schneider, Erich and Brandt, Thomas}, title = {Wie H{\"o}henschwindel die visuelle Exploration und den Gang beeintr{\"a}chtigt}, series = {Nervenarzt}, volume = {84}, journal = {Nervenarzt}, number = {10}, issn = {0028-2804}, doi = {10.1007/s00115-013-3905-6}, pages = {1233 -- 1237}, language = {de} } @article{SchneiderSchmidReif, author = {Schneider, Thomas and Schmid, Reiner P. and Reif, J{\"u}rgen}, title = {Efficent self phase matched third harmonic generation of ultrashort pulses in a material with positive dispersion}, series = {Applied Physics B}, volume = {72}, journal = {Applied Physics B}, number = {5}, issn = {0946-2171}, pages = {563 -- 565}, language = {en} } @misc{SchmidSchneiderReif, author = {Schmid, Reiner P. and Schneider, Thomas and Reif, J{\"u}rgen}, title = {Optical Processing on a Femtosecond Time Scale}, series = {Optics Communication}, volume = {207}, journal = {Optics Communication}, number = {1-6}, issn = {0030-4018}, pages = {155 -- 160}, language = {en} } @phdthesis{Schneider, author = {Schneider, Thomas}, title = {Transientes ultraschnelles Brechungsindexgitter in Barium-Fluorid: Der Einfluß des Gitters auf nichtlineare optische Ph{\"a}nomene}, publisher = {Shaker}, address = {Aachen}, isbn = {3-8265-8060-5}, pages = {II, 135}, language = {de} } @misc{GuentherBartlNaudereretal., author = {Guenther, Anna L. and Bartl, Klaus and Nauderer, Josef and Schneider, Erich and Huesmann, Alexander and Brandt, Thomas and Glasauer, Stefan}, title = {Modalitydependent indication of the subjective vertical during combined linear and rotational movements}, series = {Annals of the New York Academy of Sciences}, volume = {1164}, journal = {Annals of the New York Academy of Sciences}, issn = {1749-6632}, doi = {10.1111/j.1749-6632.2009.03849.x}, pages = {376 -- 379}, language = {en} } @misc{ZinglerKryvosheySchneideretal., author = {Zingler, Vera C. and Kryvoshey, Dmytro and Schneider, Erich and Glasauer, Stefan and Brandt, Thomas and Strupp, Michael}, title = {A clinical test of otolith function: static ocular counterroll with passive head tilt.}, series = {Neuroreport}, volume = {17}, journal = {Neuroreport}, number = {6}, issn = {0959-4965}, pages = {611 -- 615}, language = {en} } @misc{SchneiderGlasauerDieterichetal., author = {Schneider, Erich and Glasauer, Stefan and Dieterich, Marianne and Kalla, Roger and Brandt, Thomas}, title = {Diagnosis of vestibular imbalance in the blink of an eye}, series = {Neurology}, volume = {63}, journal = {Neurology}, number = {7}, issn = {0028-3878}, pages = {1209 -- 1216}, language = {en} } @misc{GeyerLuciusSchroedteretal., author = {Geyer, Thomas and Lucius, Andreas and Schr{\"o}dter, Marcus and Schneider, Marc and Sarradj, Ennes}, title = {Reduction of Turbulence Interaction Noise Through Airfoils With Perforated Leading Edges}, series = {Acta Acustica united with Acustica}, volume = {105}, journal = {Acta Acustica united with Acustica}, number = {1}, issn = {1610-1928}, doi = {10.3813/AAA.919292}, pages = {109 -- 122}, language = {en} } @misc{RichterDraganoLampertetal., author = {Richter, M. and Dragano, Nico and Lampert, Thomas and Schneider, Sven and Spallek, Jacob and Sundmacher, Leonie}, title = {Understanding the institutional context of health inequalities among young people: Study protocol for a multi-center research unit}, series = {Gesundheitswesen 2019}, volume = {81}, journal = {Gesundheitswesen 2019}, number = {08/09}, publisher = {Georg Thieme Verlag KG}, address = {Stuttgart}, doi = {10.1055/s-0039-1694623}, pages = {750 -- 751}, abstract = {Background: While health inequalities among young people are well described, the underlying mechanisms have been explored far less. Compositional and contextual characteristics of institutional contexts (e.g. kindergartens, schools) are likely to shape health inequalities among young people and may have an impact above and beyond individual-level determinants. The general research objectives of the research unit are to empirically study if characteristics of different institutional contexts are associated with the emergence of individual-level inequalities in health and c) to integrate findings from different life stages into a comprehensive theoretical model about the key mechanisms at individual and contextual levels. Methods and analysis: Building upon reviews of the existing evidence, each of the five subprojects of the research unit will analyse secondary data (cross-sectional and longitudinal surveys). The subprojects will focus on institutional contexts that serve as major socialization agents in society, such as the family, kindergarten, school, tertiary education/work, as well as the health care system. Linear or logistic multilevel modelling will be applied in order to examine the role of institutional characteristics for young people's health and health inequalities at the individual level. Ethics and dissemination: The dissemination activities include the publication of results in peer-reviewed journals, at international and national scientific conferences, as well as press releases in written and broadcast media to inform relevant stakeholders and the lay public.

In the vicinity of residential buildings or in areas needing protection, exceeding the emission limits can lead to a temporary restriction of the operation of these high performance installations. Measures are required to reduce the noise impact primarily at the source or in the immediate vicinity. The acoustic and mechanical parameters are investigated on a test bench at the Technical University of Brandenburg (BTU) Cottbus-Senftenberg as part of the drive assembly tests in cooperation with LEAG. The stages of these tests are: Run-up test. In this test the supporting roller is accelerated under test load to a circumferential speed of 10 m/s and the sound pressure level is recorded. This makes it possible to calculate the sound emission as a function of the peripheral speed; Recording the geometry of the idler gear. An accurate description of the geometry of the idler housing allows conclusions to be drawn about the possible causes of excitation. The defined characteristics serve to quantify the acoustic effect of the driven rollers and derive specifications for use in belt conveyor systems.

Open questions about RIFU formation and potential legacy effects still exist, especially related to physical soil properties. Aims Our aims were (1) to characterize the soil properties of RIFU soils and (2) to compare the drought sensitivity and the growth resistance in extremely dry years of trees growing on ridges and furrows, respectively. Methods We studied soil physical (bulk density, saturated soil hydraulic conductivity, and texture) and chemical (soil pH, soil organic matter, and nitrogen content) properties and the climate sensitivity of tree growth on RIFU systems for three study sites in Prignitz, Germany. Results RIFU systems showed a high spatial heterogeneity of soil stratigraphy due to ridge construction and increased accumulation of soil moisture and organic matter in furrows due to post-abandonment pedogenesis. Slight spatial differences in soil physical properties were found, with increased air capacity in ridge soils and higher available water contents in furrow soils. No differences in drought sensitivity were observed for trees growing on ridges and furrows, except for a wet site, where trees in furrows showed a higher sensitivity. Resistance in dry years tended to be similar or increase from furrows to ridges. Conclusions The results reflect a spatial differentiation of stratigraphy and post-abandonment pedogenesis on abandoned RIFU systems and suggest an adaption to different moisture conditions through RIFU construction. Differences in drought sensitivity of tree growth with relative land surface could only be detected for one of the three sites, where trees were found to be less drought sensitive on ridges.}, language = {en} } @misc{BonhageRaabSchneideretal., author = {Bonhage, Alexander and Raab, Thomas and Schneider, Anna and Raab, Alexandra and Ouimet, William and V{\"o}lkel, J{\"o}rg and Ramezany, Shaghayegh}, title = {From site to state -

However, a family's socioeconomic position (SEP) determines both the parental behaviour, living conditions, and child health. To understand how family characteristics may influence the development of health inequalities, this scoping review synthesised research on their mediating and moderating effects. Methods The review followed the guidelines of the PRISMA Extension for Scoping Reviews. The search included German and English peer-reviewed articles published between January 1st, 2000 and December 19th, 2019. The search in PubMed, PsycINFO, and Scopus used both free text terms in the title/abstract and index terms within linked keyword blocks: (1) family characteristics, (2) inequalities, (3) income, education, occupation, (4) bhd, (5) newborn, infant, toddler, preschooler. Two researchers independently examined eligibility for inclusion in two rounds (title/abstract; full-text). Results Of 7,089 articles identified, ten sources were included that studied family characteristics and health inequalities among 0-6 years olds. Parental rules, stress, and screentime, and TV in bedroom showed mediating effects on inequalities in behaviour problems or children's screentime. Families' negativity, single parenthood, and the number of children in the household moderated differences in impairment, health, behaviour problems, development or breastfeeding initiation. Conclusions The effect of family characteristics on early health inequalities has been sparsely investigated. The evidence supported models of family stress and investment. Further research is needed to comprehensively understand this association. Key messages Family characteristics contribute to health inequalities.

The most important environment during early childhood is the family, as it profoundly influences children's health through various characteristics. These include family processes, family structure/size, and living conditions, and are closely linked to the socioeconomic position (SEP) of the family. Although it is known that the SEP contributes to health inequalities in early childhood, the effects of family characteristics on health inequalities remain unclear. The objective of this scoping review is to synthesise existing research on the mediating and moderating effects of family characteristics on socioeconomic health inequalities (HI) during early childhood in high-income countries. Methods: This review followed the methodology of "Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews". To identify German and English scientific peer-reviewed literature published from January 1st, 2000, to December 19th, 2019, the following search term blocks were linked with the logical operator "AND": (1) family structure/size, processes, living conditions, (2) inequalities, disparities, diversities, (3) income, education, occupation, (4) health and (5) young children. The search covered the electronic databases PubMed, PsycINFO, and Scopus. Results: The search yielded 7,089 records. After title/abstract and full-text screening, only ten peer-reviewed articles were included in the synthesis, which analysed the effects of family characteristics on HI in early childhood. Family processes (i.e., rules /descriptive norms, stress, parental screen time, parent-child conflicts) are identified to have mediating or moderating effects. While families' living conditions (i.e., TVs in children's bedrooms) are suggested as mediating factors, family structure/size (i.e., single parenthood, number of children in the household) appear to moderate health inequalities. Conclusion: Family characteristics contribute to health inequalities in early childhood. The results provide overall support of models of family stress and family investment. However, knowledge gaps remain regarding the role of family health literacy, regarding a wide range of children's health outcomes (e.g., oral health, inflammation parameters, weight, and height), and the development of health inequalities over the life course starting at birth.}, language = {en} } @misc{RaabDrohanRaabetal., author = {Raab, Thomas and Drohan, Patrick J. and Raab, Alexandra and Schneider, Anna and Bonhage, Alexander}, title = {A novel view in geopedology : how small landforms from past land use affect the pedosphere}, series = {Centennial Celebration and Congress of the International Union of Soil Sciences}, journal = {Centennial Celebration and Congress of the International Union of Soil Sciences}, publisher = {Florenz}, pages = {1}, abstract = {LiDAR-based high-resolution digital elevation models (DEMs) can now provide a centimetre-accurate image of the Earth's surface. Soil science is still in the early stages of realising how fundamentally this new technology will change our understanding of the formation, properties and functions of the pedosphere and in particular the uppermost part of it, which usually represents A horizons. With the help of high-resolution DEMs, it is possible to identify and classify small topographic features that were previously not considered in soil mapping. Therefore, precise landform analyses will be crucial in assessing variations in soil horizonation and soil stratigraphy and will provide the framework for a new perspective in Geopedology that truly integrates Geomorphology and Pedology from pedon to soil landscapes. In the digital domain, this geopedological approach is growing rapidly by using artificial intelligence (AI) to automatically identify small landforms and visualise the heterogeneity of diverse pedological information. We present the results of the study of different types of relict anthropogenic landforms (RALs) and highlight their characteristics and differences compared to natural, undisturbed soils. The origins of these relict features can vary greatly, as can their distribution, morphology and age. The analysis of high-resolution relief models in Europe and the USA shows that morphological features can be found, particularly in forest that were created in pre-industrial times. Settlement structures (e.g. stone walls, burial sites) or linear relief forms created by soil cultivation (e.g. field terraces, furrow systems) are common. Relict Charcoal Hearths (RCHs), which originate from historic charcoal burning, are usually small circular platforms surrounded by pits or ditches, but can still cover a considerable part of the area. A relatively complex geomorphology can be observed in historic mining areas, which may include different landform types such as mine shafts and spoil heaps, resulting in a very heterogeneous pedological mosaic. To summarise, all studies reveal a high variation of soil properties controlled by small relief structures. Pedology should take this more into account in the future and improve knowledge of the impact of RALs on the pedosphere and other components of ecosystems.}, language = {en} }
