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

题目：合作研究：阿根廷Hombre Muerto盐湖全新世更新世盐芯的地球化学代用物。该奖项支持对Hombre Muerto盐湖50多米盐芯的古环境研究，该盐湖位于安第斯山脉中部高原东南部的一个干湖。岩心记录了湖泊的充盈和干涸的历史，因此也记录了水文和气候的变化。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。从该岩心提取的古气候数据将解决北半球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。

Abstract ATM-9632359 Lowenstein, Tim K. State University of New York - Binghamton Title: Collaborative Research: 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 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.
