Relating past occupation patterns to (paleo)environmental properties – hypothesis testing

Current archaeological discussions suggest that early human settlement distribution patterns, as preserved by the geological record, may be related to geospatial properties such as altitude, vicinity to water and habitat variability. However, to date, no quantitative analyses have been undertaken to either verify or falsify these hypotheses. In this study, data-driven methods were applied to test these hypotheses, specifically correlation and comparison of dataset variabilities. We compare the standard...

Mesolithic pits in Germany – an initial overview

Inspired by the conference „Creuser au Mésolithique / Digging in the Mesolithic“ in Châlon-en-Champagne in March 2016, the authors start a compilation of Mesolithc pits in Germany. Although it is still incomplete, some statements can be already made. Nearly 80% of the pits known until now come from settlement contexts. The majority was found in sandy soils or flood loams. Although features are known from the Early and the Final Mesolithic, the pits stem mainly from the Middle and the Late Mesolithic. The...

Hydrogeological investigations of shallow groundwater aquifers in an arid, data-scarce coastal region (El Daba’a area, Northwestern Coast of Egypt) doi

Hydrogeological investigations in arid regions are particularly important to support sustainable development. The study area, El Daba’a in northwestern Egypt, faces scarce water resources as a result of reported climate change that particularly affects the southern Mediterranean coast and increases stress on the local groundwater reserves. This change in climate affects the area in terms of drought, over-pumping and unregulated exploration ofgroundwater for irrigation purposes. The hydrogeological...

Palaeohydrological evolution and implications for palaeoclimate since the Late Glacial at Laguna de Fuente de Piedra, southern Spain doi

Here, we present a terrestrial multi-proxy record of Late Quaternary environmental changes in the southern Iberian Peninsula covering approximately 30 ka. This sedimentary record originates from a saline playa lake (Laguna de Fuente de Piedra) hosted within a complex geological setting dominated by Triassic claystones and evaporites, Jurassic carbonates and Miocene deposits leading to a complex hydrogeological setting. Dissolution of evaporites in the catchment and intense evaporation are responsible for...

Megabiome changes over the last 120kyr (HadCM3) SFB806 doi Spatial PaleoMaps

This geospatial dataset contains climate data from 120 ka to 0 ka in 1000 to 4000 year steps as raster data. The variable shows biomes representing nine different climate conditions modeled with the HadCM3 - general circulation model. The source data from Hoogakker et al. (2016) was imported from the original published NetCDF file and translated to multiple GEOTIFFs with GDAL. The raster data has been converted to single GeoTIFFs with GDAL’s gdal translate and gdalwarp tool. The dataset has a resolution of...

Unterrichtsmaterialien zur Unterrichtseinheit ‚Migration früher und heute – Wo liegen die Unterschiede in den Migrationen?‘ mit dem Fokus auf der Bearbeitung der Frage ‚Warum kam der moderne Mensch nach Europa?‘ SFB806 doi

The materials to the teaching unit „‚Migration in the past and today – Where are the differences in the migrations?’ with the focus on handling the question ‚Why did modern humans came to Europe?’” are developed in the frame of the dissertation „Argumentation as a method to solve problems: A class study to the oral argumentation of pupils in cooperative settings in geography lessons” (Sabrina Dittrich). This dissertation was written in the Collaborative Research Center 806 – ‚Our Way to Europe’. The...

Modelling causes of loess-paleosol formation in the Carpathian Basin

The effect of orbital forcing of climate in southeastern Europe can be demonstrated using climate models. Multiple linear regression models (here of the LR04 stack, obliquity and precession; Laskar et al., 2004; Lisiecki and Raymo, 2005) are rather simple models which may be used for the estimation of factors influencing dust deposition resulting in loess formation and pedogenesis in loess. Available data for the last 440 ka from loess is limited to magnetic susceptibility datasets in the area (Basarin et...

Loess distribution map for the eastern part of the Carpathian Basin: A new approach using different geoscientific maps and data

Geo- and paleo-ecological studies in the Carpathian Basin require a detailed knowledge of the distribution of aeolian sediments. Existing and often cited maps, such as Haase et al. (2007), are in not detailed enough and faulty as a result of the basic input data and due to the used scale. To create a map showing the detailed distribution of loess sediments in the Carpathian Basin at the border of Hungary and Romania several different cross-border spatial data were used. Particularly some problems occurred...

Tracing the influence of Mediterranean climate on Southeast Europe during the past 350,000 years

Loess-palaeosol sequences (LPS) are valuable archives of past environmental changes in the Eurasian loess belt. Although regional palaeoclimatic trends and conditions in Southeastern Europe (SEE) have been inferred from LPS, large scale forcing mechanisms responsible for their formation have yet to be determined. SEE is a climatically sensitive region, existing under the strong influence of both Mediterranean and continental climates. Establishment of the spatial and temporal evolution and interaction of...

Towards multi-proxy based millennial time scales in Lower Danubian Late Pleistocene Loess-Palaeosol Sequences: evidence for persistent North Atlantic sea surface temperature control

Late Pleistocene palaeoclimatic records for south-eastern Europe rely largely on loess-palaeosol sequences (LPSS). The general spatial scarcity and often limited temporal range of other sedimentary archives assign the LPSS of the region a key role even in millennial scale temporal reconstructions of the Late Pleistocene terrestrial environmental dynamics. The Eurasian loess-belt has its western end in the Middle Danube (Carpathian) and the Lower Danube Basin. Similar to the Chinese Loess Plateau...

Luminescence characteristics of quartz grains from the Titel Loess Plateau

The Titel loess plateau in the Vojvodina region of Serbia is considered to contain the most detailed terrestrial paleoclimatic records in Europe, with a thick and apparently continuous record extending through the middle and late Early Pleistocene. In the past few decades the plateau has been investigated on a fairly large scale and has provided important records of climatic and environmental changes during the Pleistocene in this part of Europe. Regardless the extensive research in the past, high detailed...
