The PI will attempt to calibrate bamboo corals from 250-2200 m water depth offshore California with the objective of developing a proxy for changes in the intermediate water properties on decadal to centennial time scales. The work will test several hypotheses about controls on coral geochemistry that will lead to proxy development for deciphering environmental changes in intermediate water depth. The development of a new potential proxy for high resolution paleoenvironmental studies, support of a graduate and undergraduate summer intern, and development of museum exhibits are considered important broader impacts.

PI将尝试从250-2200 m的加利福尼亚水深校准竹珊瑚，目的是开发代理，以变化在十年中至百年纪念尺度上的中间水性质。这项工作将检验有关珊瑚地球化学控制的几个假设，这将导致替代发展中间水深的环境变化。开发高分辨率古环境研究，研究生和本科暑期实习生的新潜在代理以及博物馆展览的发展被认为是重要的广泛影响。
