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.

提供资金用于获取美国西南部 (SW) 过去 5 万年的高分辨率洞穴气候代理数据。 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项基于洞穴生物生长率的试点项目的数据表明，新仙女木期寒冷期的过渡是渐进的，而不是像之前得出的结论那样突然。 研究小组还将研究区域气候响应的差异，以此作为了解气候突变的驱动因素的一种手段。 该项目将为环境突变及其与水文资源和季风系统的关系提供数据和更广泛的理解。 该项目还将为研究生提供教育和培训机会。
