Continental Response to Abrupt Climatic Events from Speleothem Data, Southwestern United States

提供资金以获得美国西南部（SW）过去50，000年的高分辨率洞穴气候代用数据。 具体来说，研究人员将研究更新世-全新世过渡。 研究人员最近进行的一个试点项目的数据表明，新仙女木寒冷期的过渡是渐进的，而不是突然的，正如之前得出的结论。 研究小组还将研究区域气候反应的差异，作为了解气候突变驱动因素的一种手段。 该项目将提供数据和更广泛地了解环境突变及其与水文资源和季风系统的关系。 该项目还将为一名研究生提供教育和培训机会。

Funding is provided to obtain high-resolution speleothem climate proxy data from the southwestern United States (SW) for the past 50,000 years. Specifically, the researchers will examine the Pleistocene-Holocene transition. Data from a recent pilot project, conducted by the researchers and based on speleothem growth rates, indicate that the transition across the Younger Dryas cold period was gradual and not abrupt, as previously concluded. The research team will also examine differences in the response of regional climate as a means to understand the drivers for abrupt climate change. The project will provide data and a broader understanding of abrupt environmental change and its relation to hydrologic resources and monsoonal systems. The project will also provide education and training opportunities for a graduate student.
