9503670麦考克这个项目将利用孔隙水和底栖有孔虫贝壳中稳定同位素和微量金属的化学分析,研究(1)有机物和92)金属迁移对贝壳中生物地球化学记录的影响。碳同位素和痕量金属(Cd、Ba)被广泛用作过去海洋生产和深水循环的示踪剂;Pis有初步证据表明,两者都受到早期成岩作用的影响。该项目将在地表水生产(因此,碳通量到沉积物)和沉积物氧化状态不同的一系列环境中检查这种影响。***
英文摘要
9503670 McCorkle This project will use chemistry of stable isotopes and trace metals in pore waters and in shells of benthic foraminifera to examine the effects of (1) organic matter and 92) metal remobilization upon the biogeochemical record in the shells. Carbon isotopes and trace metals (Cd,Ba) are widely used as tracers of past ocean production and deep water circulation; the Pis have preliminary evidence that both are affected by early diagenesis. The project will examine this effect in a range of environments differing in surface water production (hence, carbon flux to the sediment) and in sediment oxidation state. ***
