EAR 9814883Sloan One of the most abrupt and dramatic global warming events in the geologic record took place ~55 Ma in the late Paleocene epoch. This event, known as the Late Paleocene Thermal Maximum (LPTM), coincided with widespread extinction of deep-sea faunas and rapid radiation in surface ocean and terrestrial ecosystems. The proposed four-year study will build an integrated reconstruction of ocean, atmosphere, and biosphere immediately before and at the peak of the LPTM. We will define the timing of effusive volcanism relative to the LPTM, and we will generate and compile extensive data bases related to the LPTM. These data will be used to constrain oceanic and climatic conditions preceding and during the LPTM. The defined conditions will serve as boundary conditions and validation for atmospheric, oceanic and coupled climate models that will be used to test theories of climate change related to the LPTM.

地质记录中最突然和最剧烈的全球变暖事件之一发生在古新世晚期~55 Ma。这一事件被称为晚古新世最热期（LPTM），与深海动物群的大范围灭绝以及表层海洋和陆地生态系统的快速辐射同时发生。这项为期四年的研究将在LPTM之前和高峰时建立海洋，大气和生物圈的综合重建。我们将确定喷发火山活动相对于LPTM的时间，我们将生成和编译与LPTM相关的广泛数据库。 这些数据将用于限制LPTM之前和期间的海洋和气候条件。所确定的条件将作为边界条件和验证大气、海洋和耦合气候模型，这些模型将用于测试与LPTM有关的气候变化理论。
