Palaeohydrology and its impact on groundwater in arid environments: Gebel Duwi and its vicinities, Eastern Desert, Egypt doi Spatial

From ancient times, access to water in arid and hyper-arid regions has been crucial for life. Increased knowledge about groundwater conditions is therefore extremely important for the future development of desert areas. Gebel Duwi, a limestone ridge, sited in the today hyper-arid Eastern Desert of Egypt, was chosen for testing current hypotheses concerning the interdependence of palaeohydrologic features and geologic settings for groundwater investigations. Two sub-basins are identified in affecting Gebel...

Dead Sea pollen provides new insights into the paleoenvironment of the southern Levant during MIS 6-5 doi Spatial Temporal

The paleoclimate of the southern Levant, especially during the last interglacial (LIG), is still under debate. Reliable paleovegetation information for this period, as independent evidence to the paleoenvironment, was still missing. In this study, we present a high-resolution pollen record encompassing 147-89 ka from the Dead Sea deep drilling core 5017-1A. The sediment profile is marked by alternations of laminated marl deposits and thick massive halite, indicating lake-level fluctuations. The pollen...

Holocene vegetation history of the southern Levant based on a pollen record from Lake Kinneret (Sea of Galilee), Israel doi Spatial Temporal

Lake Kinneret, also known as the Sea of Galilee and Lake Tiberias, is located in the northeast of Israel. At a lake level of 211 m b.s.l. (below mean sea level), the central basin is 43 m deep. The maximum length of the lake is 21 km (N–S) and its maximum width is 12 km (W–E). Lake Kinneret’s surface area is 166 km². A new 17.8 m long sedimentary core was drilled in 2010. Here, we present the entire palynological record from it, which covers the last ~ 9,000 years. Special emphasis is given to the natural...

Carpatian Basin 30ky bp GIS data set SFB806 doi Spatial PaleoMaps

To provide paleoenvironmental data for a GIS and geostatistic based Species Distribution Modelling (SDM) application, this comprehensive GIS data set was created. The data set consists of DEM based topography, and of paleoclimate layers, that were used as environmental predictor variables for SDM application.

Palaeoclimate Reconstruction in the Levant and on the Balkans Spatial

For an understanding of the climate system’s variability, knowledge of the past climate is essential. Continuous observations are not available for longer than the last 100 years, a period that is insufficient to understand the variability and sensitivity of the climate system. Since information of both is necessary to build good climate models, the reconstruction of the past climate is fundamental. With palaeoclimate reconstructions it is possible to get information about the past climate and the climate...

PaleoMaps: GIS based Palaeoenvironmental data collection for the Last Interglacial (125ka) of Egypt SFB806 doi Spatial PaleoMaps

The growing number of paleoenvironmental data, GIS-based analyses and modelling allows us to produce PaleoMaps for a given area. However, the „translation“ of paleoenvironmental information in maps is even more complex, than producing maps as an illustration of the present. The CRC 806 “Our Way to Europe” provides the background to study the culture-environment interaction and human mobility in the Late Quaternary. Northeastern Africa during the Last Interglacial is thereby an important region and timespan....

Three climatic cycles recorded in a loess-paleosol sequence at Semlac (Romania) – implications for dust accumulation in south-eastern Europe doi Spatial

Recent investigations of the Semlac loess section in the south-eastern Carpathian Basin, which is situated at an undercut slope position on the right bank of the Mureş River in its lower reaches (Banat region, western Romanian), are presented and discussed. Dating back to marine isotope stage (MIS) 10, the more than 10 m thick loess sequence includes four fossil soil-complexes developed in homogenous and relatively fine silty loess. Because of the good preservation of the sediment, Semlac is regarded as a...

Vegetation and climate during the Last Glacial high stand (ca. 28–22 ka BP) of the Sea of Galilee, northern Israel doi Spatial Temporal

Despite ongoing discussions on hydroclimatic conditions in the southern Levant during the Last Glacial, detailed knowledge about the Levantine paleovegetation, which is an important indicator for the paleoclimate, is limited. To investigate the paleovegetation in northern Israel, we analyzed the pollen assemblage of a sediment core that was drilled at the Ohalo II archaeological site on the southwestern shore of the Sea of Galilee (Lake Kinneret). We refined the lithology and the age-depth model with the...

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...

Climate Data 30-13 ka GIS Dataset SFB806 doi Spatial PaleoMaps

This raster data is part of a geospatial dataset that contains climate data from 30 ka to 13 ka in 1000 year steps, provided by Tallavaara et al. (2015). The variables are PET (Potential Evapotranspiration) and WAB (Water balance) in mm/year and MCM (Mean temperature of the coldest month) in C°. The source was supplied in a .xls file containing longitude/latitude coordinates with the related variable values. It was imported to a shapefile with QGIS' "Create a Layer from a Delimited Text...

Paleocoastlines GIS dataset SFB806 doi Spatial PaleoMaps

This GIS dataset contains 23 different computed land masks of characteristic sea level high stand/ low stand with respect to the relative sea level (RSL) for events and intervals during a period from 200 ka BP until today in Europe, the Nearer East and northern parts of Africa. The sea level data was collected from modeled data published in scholarly works and derived from General Bathymetric Chart of the Oceans (2014) using the software QGIS and esri ArcMap.

Impacts of climate and humans on the vegetation in northwestern Turkey: palynological insights from Lake Iznik since the Last Glacial doi Spatial

The Marmara region in northwestern Turkey provides a unique opportunity for studying the vegetation history in response to climate changes and anthropogenic impacts because of its location between different climate and vegetation zones and its long settlement history. Geochemical and mineralogical investigations of the largest lake in the region, Lake Iznik, already registered climate-related changes of the lake level and the lake mixing. However, a palynological investigation encompassing the Late...
