The proposed project is the central part of a DFG bundle proposal of several German research institutions and is integrated in a collaborative research program, mainly with partners from European research institutions. In the framework of the ICDP project Scientific Collaboration On Past Speciation Conditions (SCOPSCO) five 20 m to 680 m deep drillings will be carried out at Lake Ohrid (Albania and Macedonia). The project aims to study age and origin of Lake Ohrid, to achieve information about geological, environmental and climate variations of Late Tertiary/Quaternary age and to determine the driving forces of the biotic development. Extensive geophysical downhole logging of these boreholes delivers a basis for answering questions in the scope of this project. Interpreting the downhole logging data permits to establish a complete lithological log, to characterize the drilled sediments petrophysically, to determine sedimentary structures and to obtain evidences about palaeoclimatic conditions likely during the last three to five million years. Seismic experiments in the borehole allow linking the detailed geological information with shipborne seismic sections. Thus, local results can be transformed into spatial information providing an important contribution to the understanding of the sedimentological patterns and the tectonic structure of Lake Ohrid.
