9810717 Rosenthal This Small Grant for Exploratory Research will support collection and analysis of bottom-water and surface-sediment samples along depth transects off the Hawaiian Islands. The PIs will analyze Cd, Ba, Sr, and Mg concentrations in the water samples and in live and dead benthic forminifera. This will (a) determine whether the organisms secrete their shells in equilibrium with the water, (b) determine whether the original signal is altered by early diagenesis and (c) provide baseline data for analysis of older sediments, representing past conditions of ocean circulation under different climate states.

9810717罗森塔尔这笔小额的探索性研究赠款将支持沿夏威夷群岛外的深度断面收集和分析底层水和表层沉积物样本。PIS将分析水样以及活的和死的底栖甲虫中的Cd、Ba、Sr和Mg的浓度。这将(A)确定生物是否分泌与水平衡的贝壳，(B)确定原始信号是否因早期成岩作用而改变，以及(C)为分析较老的沉积物提供基线数据，代表不同气候状态下过去的海洋循环条件。
