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将尝试校准加州近海250-2200 m水深的竹珊瑚，目的是开发一个代理，用于十年到百年时间尺度上的中间水特性变化。这项工作将检验关于控制珊瑚地球化学的几个假设，这将导致替代发展，以破译中间水深的环境变化。高分辨率古环境研究，研究生和本科生暑期实习生的支持，和博物馆展品的发展，一个新的潜在代理的发展被认为是重要的更广泛的影响。
