中文摘要
小行星9810717 这项探索性研究的小额赠款将支持收集和分析夏威夷群岛附近沿着深度断面的底层水和表层沉积物样本。 PI将分析水样中以及活的和死的底栖forminifera中的Cd、Ba、Sr和Mg浓度。 这将(a)确定生物体是否分泌出与水平衡的外壳,(B)确定原始信号是否因早期成岩作用而改变,(c)提供基线数据,用于分析较老的沉积物,这些沉积物代表过去不同气候状态下的海洋环流状况。
英文摘要
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.
