Collaborative Research: Andean Climate History: Geochemical Proxies from a Holocene-Pleistocene Salt Core, Salar Del Hombre Muerto, Argentina

Am-9631291约旦，Teresa Cornell大学标题：合作研究：安第斯气候历史：来自阿根廷Salar Del Hombre Muerto全新世更新世盐芯的地球化学指标该奖项支持对Hombre Muerto Salar盐芯的古环境研究，Hombre Muerto Salar是安第斯山脉东南部高原/普纳高原东南部的一个干燥湖泊。岩芯记录了湖泊的充填和干化历史，因此也是追溯到过去的水文和气候变化的记录。在南美洲，末次冰盛期和全新世的气候历史是有争议的，而在第四纪之前，它几乎是未知的。从这个核心提取的古气候数据将处理南北半球气候循环的相对时间，以及安第斯山脉降水循环和温度循环之间的时间位相关系。

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.
