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.

Recently, a joint research project was launched for interdisciplinary long-term palaeoenvironmental research and to study anthropogenic landscape change in southern Brandenburg. The project partners are geoscientists from the Brandenburg University of Technology (BTU) Cottbus and archaeologists from the Brandenburgisches Landesamt f{\"u}r Denkmalpflege und Arch{\"a}ologisches Museum (BLDAM), within the scope of this project pedological and geomorphological investigations are carried out to reconstruct Holocene landscape and land use change in the apron of the opencast pit J{\"a}nschwalde (Lower Lusatia), c. 100 southeast of Berlin and c. 15 km northeast of Cottbus. By law large-scale surveys and excavations have to be carried out in the forefield to document all archaeological findings. In combination with the excellent outcrop situation the archaeological investigation offers ideal conditions to study the soil geomorphology on a landscape scale. Fieldwork includes topographical surveying by differential GPS. Soils and sediments are described along cross-sections (up to 140 m long, up to 2 m deep). Field-portable XRF analyzes (FPXRF) is used for a quick characterization of total element concentrations of the substrates. Standard analytical methods (e.g., soil texture, contents of pedogenic oxides) are carried out in the laboratory. To obtain chronological information, radiocarbon and OSL (optically stimulated luminescence) dating are applied on suitable material. Evidence of different land use and land use change in the study area is abundant. For example, at several cross-sections agricultural soil horizons are covered with up to 150 cm thick eolian sands, proving that deforestation and agricultural use induced eolian soil erosion. In addition, remnants of charcoal piles buried under up to 150 cm thick eolian sands indicate remobilization of Quaternary sands as a consequence of clearing for charcoal production.

Wir geben einen {\"U}berblick {\"u}ber die wichtigsten Erkenntnisse der letzten Jahre, pr{\"a}sentieren aktuelle Ergebnisse und zeigen zuk{\"u}nftige Forschungsfelder auf. Im Tagebau J{\"a}nschwalde sind zwischenzeitlich mehr als 1000 Relikte von Holzkohlmeilern (HKM) als Zeugen einer intensiven historischen Holznutzung arch{\"a}ologisch dokumentiert. Mit Stand Januar 2016 liegen Dendroalter von 64 HKM vor. Die Alter schwanken zwischen dem ausgehenden 16. Jahrhundert und der Mitte des 19. Jahrhunderts, was in etwa dem Betriebszeitraum des H{\"u}ttenwerks in Peitz entspricht. Die Mehrzahl der Meiler datiert auf den Beginn des 18. Jahrhunderts. Weitere Hinterlassenschaften der historischen Landnutzung sind u.a. W{\"o}lb{\"a}cker und begrabene Ackerb{\"o}den.

Einige Relikte von HKM sind mit Sand {\"u}berweht worden, und an einer Stelle konnte das Alter dieser {\"a}olischen Sedimentation mittels Dendrodatierung des begrabenen Meilers auf1850 oder j{\"u}nger bestimmt werden. Allerdings stellt dies die Ausnahme dar. Der weitaus gr{\"o}ßere Teil der HKM-Relikte liegt direkt an der Oberfl{\"a}che und ist nicht begraben, was auf eine sehr geringe Winderosion in der Neuzeit schließen l{\"a}sst.

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.

Principles controlling development and distribution of these chernozem subtypes along the ecotone transect are quite well known. However, intensive land use over the last century has affected soils that originally have formed under natural conditions during the Holocene in more than 10,000 years. There is a lack of knowledge regarding soil development in these landscapes on the decadal to centennial time scale. Within this time frame the most important factor of soil formation may be relief, although this has not been properly studied. This study aims to compare soil properties in a typical chernozem landscape where soils have been highly disturbed and parent materials have been re-arranged by surface coal mining.We hypothesize that within 50 years, soils develop with significant differences based on vegetation type and slope aspect. Our study site is the former Diplomat Mine near Forestburg, Alberta where spoils form a small scale ridge and graben topography. The south facing slopes of the piles are covered by grassland, whereas on the north exposition has trees and shrubs. Samples were taken from six sites with differences in topography and vegetation type. Diplomate T1 is at the top of the ridge with grassland, Diplomate S1 is on the southern slope with grassland, Diplomate N1 is on the northern slope with trees, and Diplomate N2 is on the northern slope with shrubs. For comparison we took samples from two sites without slope aspect. One site was an undisturbed grassland (Diplomate Z1) and the other sites were reclaimed piles (Diplomate R1). At each site, five soil profiles were examined and volumetrically sampled (250 cm3 steel ring) in steps of five centimeters to a depth of 30 centimeters. We present first results of basic physical and chemical soil parameters (bulk density, water content, pH, Cstock, N-stock).}, language = {en} } @inproceedings{SchneiderHirschRaabetal., author = {Schneider, Anna and Hirsch, Florian and Raab, Alexandra and Bonhage, Alexander and Raab, Thomas}, title = {Assessing the legacy effects of historic charcoal production in Brandenburg, Germany}, series = {European Geosciences Union, General Assembly 2017, Vienna, Austria}, booktitle = {European Geosciences Union, General Assembly 2017, Vienna, Austria}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, abstract = {Charcoal produced in kilns or hearths was an important source of energy in many regions of Europe and Northern America until the 19th century, and charcoal production in hearths is still common in many other regions of the world. 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{RaabSchneiderBonhageetal., author = {Raab, Alexandra and Schneider, Anna and Bonhage, Alexander and Raab, Thomas and Hirsch, Florian}, title = {Extensive historical charcoal production in Brandenburg (Germany) - identification of potential areas by GIS analysis}, series = {European Geosciences Union, General Assembly 2017, Vienna, Austria}, booktitle = {European Geosciences Union, General Assembly 2017, Vienna, Austria}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, abstract = {We used a GIS analysis of environmental and historical data to identify potential areas of extensive charcoal production in Brandenburg. The analysis was based on three assumptions (i to iii). Large charcoal kiln fields can be found in areas that i) are close to historical industrial sites, ii) are close to bog iron ore deposits, and iii) have been continuously covered by forest during the last centuries. 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. Although further parameters and study areas need to be considered in the model in order to explain the spatial distribution patterns of charcoal production, the results indicate correlations between the location of bog iron ore deposits, historic ironworks and charcoal kiln fields.}, language = {en} } @inproceedings{SchneiderHirschWechleretal., author = {Schneider, Anna and Hirsch, Florian and Wechler, Klaus-Peter and Raab, Alexandra and Raab, Thomas}, title = {Mapping a paleosurface and archaeological site location in an inland dune area in Brandenburg, Germany}, series = {European Geosciences Union, General Assembly 2017, Vienna, Austria}, booktitle = {European Geosciences Union, General Assembly 2017, Vienna, Austria}, publisher = {European Geophysical Society}, address = {Katlenburg-Lindau}, abstract = {Mapping and visualizing the position of archaeological remains in the surface relief provides important basic information for archaeological survey design and interpretation. 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.

Charcoal as raw material was crucial for production of iron in iron works and hence numerous charcoal hearths can be found in the forests near historic iron works in Europe as well as the Eastern United States. 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. The presence of residual products from charcoal production classifies the soils as Anthropic Udorthents (US Soil Taxonomy) or Spolic Technosols (Humic) according to the World Reference Base for Soil Resources.

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. Thus, the soils in the RCHs could be classified as Kolluviale Braunerde.}, language = {en} } @misc{SchneiderHirschRaabetal., author = {Schneider, Anna and Hirsch, Florian and Raab, Alexandra and Raab, Thomas}, title = {Bodenkundlich-geomorphologische Untersuchung von Meilerpl{\"a}tzen um Weiherhammer}, series = {Beitr{\"a}ge zur Arch{\"a}ologie in der Oberpfalz und in Regensburg}, volume = {12}, journal = {Beitr{\"a}ge zur Arch{\"a}ologie in der Oberpfalz und in Regensburg}, issn = {1617-4461}, pages = {433 -- 448}, language = {de} } @misc{SchneiderHirschRaabetal., author = {Schneider, Anna and Hirsch, Florian and Raab, Alexandra and Raab, Thomas}, title = {Dye Tracer Visualization of Infiltration Patterns in Soils on Relict Charcoal Hearths}, series = {Frontiers in Environmental Sciences}, volume = {6}, journal = {Frontiers in Environmental Sciences}, doi = {doi.org/10.3389/fenvs.2018.00143}, pages = {1 -- 14}, 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{HirschRaabOuimetetal., author = {Hirsch, Florian and Raab, Thomas and Ouimet, William and Dethier, David and Schneider, Anna and Raab, Alexandra}, title = {Soils on Historic Charcoal Hearths: Terminology and Chemical Properties}, series = {Soil Science Society of America, International Soils Meeting, Soils Across Latitudes, San Diego 2019}, journal = {Soil Science Society of America, International Soils Meeting, Soils Across Latitudes, San Diego 2019}, language = {en} } @misc{BonhageHirschSchneideretal., author = {Bonhage, Alexander and Hirsch, Florian and Schneider, Anna and Raab, Thomas and Raab, Alexandra and Ouimet, William and Drohan, Patrick J.}, title = {Effects of Historical Charcoal Burning on Soil Landscapes in West Connecticut, USA}, series = {Soil Science Society of America, International Soils Meeting, Soils Across Latitudes, San Diego 2019}, journal = {Soil Science Society of America, International Soils Meeting, Soils Across Latitudes, San Diego 2019}, language = {en} } @misc{SchneiderHirschRaabetal., author = {Schneider, Anna and Hirsch, Florian and Raab, Thomas and Raab, Alexandra}, title = {The temperature regime of a charcoal-enriched land use legacy soil}, series = {Soil Science Society of America Journal}, volume = {83}, journal = {Soil Science Society of America Journal}, number = {3}, issn = {1435-0661}, doi = {10.2136/sssaj2018.12.0483}, pages = {565 -- 574}, language = {en} } @misc{DonovanSchneiderHirschetal., author = {Donovan, Sally and Schneider, Anna and Hirsch, Florian and Bonhage, Alexander and Raab, Alexandra and Raab, Thomas}, title = {Thermal conductivity of charcoal-richsoils-preliminary results from a study on relict charcoal hearth (RCH) sites from Germany and the USA}, series = {European Geosciences Union, General Assembly 2019, Vienna, Austria, 7-12 April 2019}, journal = {European Geosciences Union, General Assembly 2019, Vienna, Austria, 7-12 April 2019}, address = {Katlenburg-Lindau}, pages = {1}, language = {en} }
