Marine Geochemistry of Reactive Radiouclides

该提案要求提供新的资金，以完成对天然衰变系列放射性核素的行为及其在海洋水柱中的化学清除和粒子动力学问题上的应用的研究。将在一年赠款期间执行的任务是：1)在百慕大近海马尾藻海的一个站完成一年来溶解和粒子晚期放射性核素分配的记录；2)在北太平洋；3)解释和公布一组累积的海洋水柱中放射性核素分布和通量的数据。这些研究将有助于我们了解海洋如何处理添加到海洋中的化学物质，并有助于更好地了解海洋中的颗粒通量和动力学，这些问题是海洋化学、生物学和地质学广泛关注的问题。

This proposal requests renewed funding to complete studies of the behavior of natural decay-series radionuclides and their applications to problems of chemical scavenging and particle dynamics in the oceanic water column. Tasks that will be carried out during the one-year grant period are: 1) completion of a one-year record of dissolved and particu- late radionuclide distributions at a station in the Sargasso Sea off Bermuda; 2) in the North Pacific; and 3) interpreta- tion and publication of an accumulated set of data on radio- nuclide distributions and fluxes in the oceanic water column. These studies will contribute to our understanding of how the oceans process chemical substances added to them and to a better understanding of particle fluxes and dynamics in the oceans, issues that are of broad concern to marine chemistry, biology, and geology.
