Abstract ATM-9631291 Jordan, Teresa Cornell University Title: Collaborative Research: Andean Climate History: Geochemical Proxies from a Holocene Pleistocene Salt Core, Salar Del Hombre Muerto, Argentina This award supports a paleoenvironmental study of a 50+meter salt core from Hombre Muerto salar, a dry lake in the southeastern Altiplano/Puna plateau of the Central Andes. The core is a register of the history of fill and desiccation of the lake, and is thus a record of the changes in hydrology and climate extending back through time. In South America, the climate history of the Last Glacial Maximum and the Holocene is controversial, and prior to the Quaternary, it is virtually unknown. Paleoclimate data extracted from this core will address the relative timing of northern and southern hemisphere climate cycles, and the temporal phase relations between precipitation cycles and temperature cycles in the Andes.

摘要ATM-9631291约旦，特蕾莎康奈尔大学标题：合作研究：安第斯气候历史：来自全新世更新世盐芯的地球化学指标，Salar Del Hombre Muerto，阿根廷 该奖项支持对Hombre Muerto salar 50米以上盐芯的古环境研究，Hombre Muerto salar是安第斯山脉中部高原/普纳高原东南部的一个干湖。 岩芯记录了湖泊的填充和干涸历史，因此也是水文和气候变化的记录。 在南美洲，末次盛冰期和全新世的气候历史是有争议的，在第四纪之前，它几乎是未知的。 从该岩芯中提取的古气候数据将解决北方和南半球气候周期的相对时间，以及安第斯山脉降水周期和温度周期之间的时间相位关系。
