9709145 Markgraf This project involves a 2-year pilot study, Phase 1, of the Patagonian Lake Drilling Project (PATO), a multi-disciplinary, international effort to recover, for the first time, long paleoenvironmental and paleoclimate records from three extra-Andean closed lake basins in Argentina. These basins lie along a transect from the subtropical to the temperate latitudes of southern South America. Previous studies on shoreline features from the three basins document major changes in lake levels during the late Pleistocene, and suggest high sensitivity to climate change in the accumulated sediments. The objectives of the Phase 1 project are: 1)to survey and sample the modern lake and terrestrial environments for climate calibration of the sediment record; 2) to undertake seismic surveys of the sediments, to identify optimal core sites; and 3) to collect and analyze short cores to determnine the paleoclimatic potential of the records. An international group of experts in the field of paleolimnology and paleoclimatology is collaborating, from Argentina, Germany, Switzerland, and the US. In addition, substantial portions of this collaboration are supported by other funding sources: Germany (Deutsche Forschungsgemeinschaft); Switzerland (Schweizer Nationalfond); the Lamont Doherty Earth Observatory; and the Argentine Geological Survey. PATO is a contribution to the long- term collaborative effort of the Pole-Equator-Pole paleoclimate transect of the Western Hemisphere (IGBP-PAGES-PEP 1). ***

小行星9709145 该项目涉及巴塔哥尼亚湖钻探项目（PATO）的第一阶段，为期两年的试点研究，这是一项多学科的国际努力，旨在首次恢复阿根廷三个安第斯山脉外封闭湖盆的长期古环境和古气候记录。 这些盆地沿着一条从南美洲南部亚热带到温带纬度的横断面分布。 以往对这三个盆地海岸线特征的研究记录了晚更新世期间湖泊水位的重大变化，并表明累积沉积物对气候变化的高度敏感性。 第一阶段项目的目标是： 1）对现代湖泊和陆地环境进行调查和取样，以便对沉积物记录进行气候校准; 2）对沉积物进行地震调查，以确定最佳岩心位置; 3）收集和分析短岩心，以确定记录的古气候潜力。 来自阿根廷、德国、瑞士和美国的一个古湖泊学和古气候学领域的国际专家小组正在合作。 此外，这一合作的很大一部分得到了其他资金来源的支助：德国（Deutsche Forschungsgemeinschaft）;瑞士（Schweizer Nationalfond）;拉蒙多尔蒂地球观测站;以及阿根廷地质调查局。 PATO是对西半球极地-赤道-极地古气候样带（IGBP-PAGES-PEP 1）长期合作努力的贡献。 ***
