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...

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...

A QGIS plugin to interface openModeller SFB806 doi

This is a plugin for QGIS to interface the openModeller software package. OpenModeller is a software framework for species’ potential distribution modelling. The package includes (among other program files) the om_console.exe executable which is used for the modelling process. The program file is controlled by a configuration file and needs several files as input data. The configuration file contains the paths to the input data, configuration parameters for the output data and the selected modelling...

Environmental change indicated by grain-size variations and trace elements: examples from two different sections - the sandy-loess sediments from the Doroshivtsy site (Ukraine) and the loess section Semlac (Romania) doi

Loess sequences provide important and at least a partial continuous record of Quaternary palaeoenvironmental change; some of the sequences even bury archaeological remains. In addition, loess-palaeosol sequences provide valuable information concerning environmental change and climate evolution. In this study, we compare two sections: (1) The Middle to Late Pleistocene loesspaleosol section of Semlac in western Romania (MIS 10 – 1), and (2) the sandy-loess section of Doroshivtsy in western Ukraine (MIS...

Testing feldspar against quartz luminescence dating of the sandy loess sediments from the Doroshivtsy site (Ukraine) doi

Post-infrared infrared stimulated luminescence (pIRIR) dating has reactivated the use of feldspar minerals to date Pleistocene deposits. We compared pIRIR stimulation measured at 290 °C (pIRIR290) of coarse grain feldspar (100–200 μm) and optically stimulated luminescence (OSL) of coarse grain quartz (100–150 μm) with radiocarbon dating. The samples were taken from the lower part of the Doroshivtsy sandy loess sequence, which contains Gravettian artefact layers. The site is one of the very few sections in...

LGM sealevel change (HiRes) Spatial PaleoMaps

Based on the GEBCO 2014 dataset [1], the area between the 0m coastline of today and the -120m coastline of the Last Glacial Maximum (LGM), is derived and provided in this dataset. To achieve a more realistic and higher resoluting coastline, for producing larger scale maps, the gebco dataset was interpolated from the 30 arc seconds original resolution, to a 0,001 degree resoluting raster.

Paleolimnology of Lake Iznik (NW Turkey) during the past ~ 31 ka cal BP Spatial

Lake Iznik, situated in the Marmara region (NW Turkey), is an alkaline lake with about 300 km2 surface area, inserted in an area of typical Mediterranean climate. During the dry summer season, carbonates are precipitating from the water column. The endogen carbonate accumulation, e.g. aragonite, is expected to hold past climate information. A detailed understanding of the limnological system is required to differentiate site specific signals and responses to climatic forcing. Geochemical and mineralogical...

Vegetation and climate history of the southern Levant during the last 30,000 years based on palynological investigation

Paleo-vegetation of northern Israel is reconstructed from palynological data over the Late Pleistocene and Holocene, and related to climate variation in the Levant, as well as anthropogenic impact on vegetation. Being located in the arid-to-semi-arid climatic transitional zone, the modern and past vegetation in northern Israel comprises both, Mediterranean macchia, and Irano-Turanian steppe assemblages, and thus is highly sensitive to climate change. Palynological analyses were carried out on two...

Late Neanderthals at Jarama VI (Central Iberia)? doi

Previous geochronological and archaeological studies on the rock shelter Jarama VI suggested a late survival of Neanderthals in central Iberia and the presence of lithic assemblages of Early Upper Paleolithic affinity. New data on granulometry, mineralogical composition, geochemical fingerprints and micromorphology of the sequence corroborate the previous notion that the archaeological units JVI.2.1 to JVI.2.3 are slackwater deposits of superfloods, which did not experience significant post-depositional...

A resistivity-depth model of the central Azraq basin area, Jordan: 2D forward and inverse modeling of time domain electromagnetic data

The focus of this thesis is the geophysical exploration of the central part of the Azraq basin in the northeastern desert of Jordan. In addition to common 1D inversion techniques, further 2D forward modeling strategies and a rarely used 2D inverse modeling scheme are applied to transient electromagnetic data. The Azraq area is of potential interest for palaeoclimatical and archaeological research in the frame of the interdisciplinary Collaborative Research Centre 806, entitled "Our Way to Europe" (CRC 806)....
