The present Dead Sea is located in the lowest continental elevation on Earth that has been intermittently filled by several water bodies during the Neogene-Quaternary periods. Thus, the sedimentary fill of the Dead Sea Basin (DSB) comprises an archive of the limnological-hydrological-seismic histories of the region, which have been modulated by global climate and rift transform fault tectonics. An international team of scientists is cooperating in the Dead Sea Deep Drilling Project (DSDDP) within the framework of an International Continental Scientific Drilling Program (ICDP) initiative. The combination of the data obtained from the exposed (onshore) sedimentary sections and the cores is providing high-resolution paleo-climatic and paleo- seismic records of the DSB for at least the last ca. 200 ka BP. The existing seismic information will be amalgamated with that of basin development and rift tectonics, and these new paleohydrological and paleoclimate datasets will be integrated and evaluated in the framework of global climate modeling.The retrieved cores are the result of several decades of extensive study in the DBS. The activity of the various research groups involved in this ICDP project has led to the development of new geochemical approaches, absolute dating methods, lake level reconstruction, paleomagnetism and cosmogenic isotope studies, as well as pioneering paleoseismic investigations. Within the framework of this project these scientific groups are leading the research on the sediment cores using their excellent analytical facilities. Additionally, the DSB has been a major route of human migration and development, and the modern Dead Sea has enormous economic importance. Thus, the proposed research is providing an important contribution to the understanding of the environmental conditions that accompanied human development during the middle to late Quaternary and will help shaping the future of the DSB. The Swiss research contribution to this international project is centered in investigating the living microbial communities within the sediments to characterize the subsurface biosphere in such a unique extreme environment. It emphasizes integrated studies of microbiology, geochemistry (interstitial waters), and mineral authigenesis/diagenesis. It combines a novel approach in lacustrine systems analyzing the 16S rRNA gene and other functional genes as well as fluid inclusions in the evaporite intervals.This proposal follows on previous SNF-funded ICDP projects and is part of the long-term Swiss scientific efforts to reconstruct Quaternary climates using continental records. It seeks resources to cover the salary and laboratory costs of a PhD student thesis centered on investigations of the subsurface biosphere in this extreme environment.
