Lay summary
An international team of scientists cooperates within the framework of the International Continental Scientific Drilling Program (ICDP) in the Potrok Aike Maar Lake Sediment Archive Drilling Project (PASADO). The Swiss contribution to this project includes two ongoing doctoral thesis on the long sedimentary cores retrieved in October/November 2008 from Laguna Potrok Aike, a 770 ka old maar lake in the dry steppe of the province of Santa Cruz, Argentina. Preliminary dating indicate that the recovered sediments contain a paleoenvironmental record spanning at least the last fifty thousand years allowing to develop a comprehensive environmental, climatic and volcanological dataset and thus providing unprecedented information on climate variability in the Southern Hemisphere. The recovered sediments are used to test hypotheses related to high-resolution quantitative climate and environmental reconstructions from orbital and suborbital (multimillennial) down to decadal timescales. These reconstructions are supported by multiple dating and stratigraphic correlations with emphasis on marine - ice core - terrestrial linkages and incorporation of results from GCM climate simulations. The Swiss contribution to this international project is centered in two major fields,-paleoenvironmental reconstruction using diatom remains;-investigations in living microbial communities within the sediments to characterize the subsurface biosphere in such a unique maar environment emphasizing integrated studies of microbiology, geochemistry (pore waters), and mineral authigenesis/diagenesis. This project follows on previous NSF-funded studies in Patagonia and is part of the long-term Swiss scientific efforts to reconstruct Quaternary climates in the Southern Hemisphere using continental records.

Abstract

An international team of scientists cooperates within the framework of the International Continental Scientific Drilling Program (ICDP) in the Potrok Aike Maar Lake Sediment Archive Drilling Project (PASADO). The present proposal seeks funds to accomplish two ongoing doctoral thesis on the long sedimentary cores retrieved in October/November 2008 from Laguna Potrok Aike, a 770 ka old maar lake in the dry steppe of the province of Santa Cruz, Argentina. Preliminary dating indicate that the recovered sediments contain a paleoenvironmental record spanning at least the last sixty thousand years allowing to develop a comprehensive environmental, climatic and volcanological dataset and thus providing unprecedented information on climate variability in the Southern Hemisphere. Within the framework of an international and interdisciplinary scientific approach the recovered sediments are used to test hypotheses related to high-resolution quantitative climate and environmental reconstructions from orbital and suborbital (multimillennial) down to decadal timescales. These reconstructions are supported by multiple dating and stratigraphic correlations with emphasis on marine - ice core - terrestrial linkages and incorporation of results from GCM climate simulations. The Swiss contribution to this international project is centered in two major fields,-paleoenvironmental reconstruction using diatom remains;-investigations in living microbial communities within the sediments to characterize the subsurface biosphere in such a unique maar environment emphasizing integrated studies of microbiology, geochemistry (pore waters), and mineral authigenesis/diagenesis. This proposal follows on previous NSF-funded studies in Patagonia and is part of the long-term Swiss scientific efforts to reconstruct Quaternary climates in the Southern Hemisphere using continental records. Thus, it also contains a modeling section to be carried out by a postdoctoral researcher that will integrate results of this project with comparable data from our previous investigations in Patagonia and the Pampas.
