Analyzing two-dimensional effects in central loop transient electromagnetic sounding data using a semi-synthetic tipper approach doi

We present a simple and feasible approach to analyze and identify two dimensional (2D) effects in central loop transient electromagnetic (TEM) sounding data and the correspondingly derived quasi 2D conductivity models. The proposed strategy is particularly useful to minimize interpretation errors. It is based on the calculation of a semi-synthetic TEM-tipper at each sounding and for each observational transient time point. The semi-synthetic TEM-tipper is derived from the measured vertical component of the...

Scales in Geoarchaeology beyond “a site”: The advance of a (Archaeo-)geomorphological perspective

The poster present an enlarged approach of scales for geoarchaeology-archaeogeomorphology, based on different sizes of relief forms, as (semi-) quantitative differentiation of various scales. With this classification, small-scale features related to “on-site” investigations can be integrated to the existing considerations of scale in geoarchaeology, but are expanded by characteristics of the landscape beyond the influence of a site. We apply this concept to the Eastern Desert of Egypt, as it is a key...

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....

Out of Africa: Geoarchaeological research in the Eastern Desert of Egypt

It is generally agreed upon that modern man came from Africa to Eurasia sometime in the last 100,000 years; academics do not, however, always agree on the routes that were taken. This question is the focus of the Collaborative Research Centre 806 (CRC 806; “Our Way to Europe: Culture-Environment Interaction and Human Mobility in the Late Quaternary” based at the universities of Cologne, Bonn and Aachen. Within the framework of this large-scale project (funded by the...

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

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...

Late Pleistocene Rockshelter Stratigraphies and Palaeoenvironments in Northeastern Africa - Case Study Mochena Borago (Ethiopia) Temporal

Multiskalige Untersuchungen zur Rekonstruktion geomorphologischer Prozesse im Abri Mochena Borago (Äthiopien) und seinem Einzugsgebiet Spatial Temporal

In prehistoric times the rock shelter Mochena Borago served as a retreat for anatomically modern humans in the southwestern Ethiopian Highlands. During the last decade archaeo-logical analyses helped to gain insight into the history of settlement of the rock shelter in the last 50 ka. Element and micromorphological analyses as well as computer-supported large scale investigations for sediment sources and transport into the rock shelter itself were carried out to understand the depositional history of...

Living at the lakeshore. Early Nubian Complex site associated with a lacustrine environment SFB806 doi Temporal

By analysing satellite images of the area around Sodmein Cave numerous well-preserved surface remnants (terraces) could be documented. Surveys on these old terraces, showing mainly a dark desert pavement, yielded preferentially Pleistocene artefact concentrations. Hence, it became clear that these terraces represent parts of the former Pleistocene surface of the area. During surveying activities on such terraces a new archaeological site – preliminary named as “Sodmein Playa” 14/01 – was discovered around 3...

Multi-Scale Dimension of Relief in Geoarchaeology. A base for reconstructing Late Pleistocene environments in the Eastern Desert of Egypt SFB806 doi Spatial Temporal

Scale, spatial and temporal, is one of the most important issues to deal with, when reconstructing former environments and landscapes in context of geoarchaeology. We present remote sensing investigations of different scales in order to answer crucial questions about late Pleistocene terrain environment as one important aspect for the migration of anatomically modern humans in Northeast Africa.

Geomorphological Investigations of Desert Pavements and Wadi Terraces in the Eastern Desert of Egypt SFB806 doi Temporal

The mountainous Eastern Desert of Egypt is an extremely eroded environment where the conditions to encounter Pleistocene palaeoenvironmental geoarchives are very rare. Dominated by outcrops of Precambrian basement, the drainage system is characterized by relatively short wadis with small catchment areas (figure 1). The limestone hogback of Djebel Duwi is one of the exceptional regions within the Eastern Desert which provides a significant amount of quaternary deposits, mainly wadi terraces at the eastern...
