Sediment sequence and site formation processes at the Arbreda Cave, NE Iberian Peninsula, and implications on human occupation and climate change during the Last Glacial doi

The Arbreda Cave provides a detailed archaeological record of the Middle to Upper Palaeolithic and is a key site for studying human occupation and cultural transitions in NE Iberia. Recently, studies of lake archives and archaeological sites presented new evidence on climate changes in NE Iberia correlating with Heinrich events. It, therefore, needs to be determined whether climate signals can be identified in the cave sequence of Arbreda, and if so, whether these signals can be correlated with...

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)....

How to exchange data between DB Systems on Early Humans. A case study based on the SFB 806 DB and the ROCEEH ROAD system SFB806 doi

In the recent past data base systems providing information on early humans and their environment are becoming more and more important and increase rapidly in number. However, this increase in different DB systems is concomitant with an increasing redundancy in the digital information stored in these database systems. Therefore, in this study we explore ways to reduce redundancies due to multiple storage of data and, hence, we show solutions to minimize the requirements to store and manage digital...

Investigation of the Azraq Basin, Jordan using Integrated Geoelectrical Techniques: 2D Modeling of Transient Electromagnetic Data

The Eastern Mediterranean has been the passageway for human migration from Africa to the Middle East, the Balkans and Europe. The Azraq basin in the eastern desert of Jordan has been a major spot for human settlements since the middle Pleistocene. The former lake in the basin center has developed to a 10 km × 10 km large hyper-saline alluvial mudflat, the Qa’ Al Azraq. In the basin center thick sequences of alluvial sediments, consisting mostly of clay and various evaporates, are deposited. We utilized the...

Geophysical field data recorded in Azraq, Jordan in 2011/2012

The central loop transient electromagnetic data were recorded in the central Azraq basin area, Jordan in two field surveys in 2011 and 2012. Two transects 5 km and 7 km long transects were investigated from the peripherie of the Azraq mudflat across its center. In total 150 soundings were recorded using either a 100x100 m transmitter loop for deep investigations down to approx. 120 m depth, or a 50x50 transmitter loop for fast transmitter turn-off times and shallow investigation. The data is processed, i.e....

A semantic wiki as repository to review published palaeo-data in East Africa SFB806 doi Spatial

Our research interests in palaeo-studies in East Africa remain high, partly because of the Out-of-Africa hypotheses predicting Homo sapiens origin to be situated in East Africa. Since several decades archaeologists and geoscientists explore suitable sites to answer related questions. Simultaneously, analytical methods applied to the archives improved in their sensibility or resolution over the given time. The amount of published scientific data is enormous, but has to be carefully checked on their...

Investigation of the Azraq sedimentary basin, Jordan using integrated geoelectrical and electromagnetic techniques doi

The Eastern Mediterranean has been used as a passageway for human migration from Africa to the Middle East, the Balkans and Europe. The Azraq basin in the eastern desert of Jordan has been a major spot for human settlements since the middle Pleistocene. The former lake in the basin centre has developed to a hyper-saline alluvial mudflat, the Qa’ Al Azraq. In the mudflat thick sequences of alluvial sediments are deposited. Such sediment successions are promising archives used for reconstructing a...

CRC806-Database: Integrating Typo3 with GeoNode and CKAN SFB806 doi

This Poster contribution for the 2nd Research Data Management Workshop, held on November 27th and 28th at the University of Cologne, describes the advancements of the new CRC806-Databse frontend. It was decided to update the system with some major changes to the overall architecture, by preserving the current API functionality and the URLs of the datasets in the database. This paper describes the system architecture of the upcoming version of the CRC806-Database. The SDI part of the system is migrated from...

Preliminary comparison of geological climate proxies with GCM palaeoclimate simulations for selected locations in North Africa

Our knowledge of palaeoclimate history is mainly based on climate proxies, which can infer past climatic conditions. In North Africa, sediment proxies such as palygorskite and the kaolinite-to-chlorite ratio are usually transported as dust components. Their relative increase or decrease is indicative of an arid or humid condition respectively. Another way to understand palaeoclimate conditions is by the use of coupled atmospheric models within the Paleoclimate Modelling Intercomparison Project Phase III...

Implementation des Metadatenmanagement von Geodaten der SFB806-Datenbank SFB806 doi

Die vorliegende Arbeit beschreibt die Implementation des Metadatenmanagements für Geodaten aus den Projekten des SFB806. Es soll ein internetbasiertes Informationssystem geschaffen werden, das den Mitgliedern des Pro jektes ermöglicht, Daten an einer zentralen Stelle zu veröffentlichen und somit der projektinternen Forschungsgemeinschaft zugänglich zu machen. Das Informationssystem soll eine sichere und nachhaltige Archivierung der Forschungsergebnisse aus den Projekten des SFB806 gewährleisten und...
