项目摘要
The investigators propose to use the naturally occurring isotope beryllium-7, which is produced in the atmosphere by cosmic rays and has a 53.3-day half-life, as a tracer for estimating the atmospheric fluxes of a variety of trace elements to the surface of the Arctic Ocean. They have collected samples of snow, sea ice, surface waters, and atmospheric aerosols through an international collaboration concurrent with the preparation of this proposal. This project provides funding for the analysis of Be-7 and for trace elements including aluminum, manganese, iron, cupper, zinc, cadmium, and lead. The atmospheric input of numerous chemical species into the global ocean has been shown to equal or exceed that from river sources. In the Arctic, several contaminant elements in particular are dominated by atmospheric sources, with implications for the Arctic ecosystem and human health. The project will investigate several elements of interest to the international GEOTRACES program, which is currently formulating plans for coordinated Arctic work. The project will support a Ph.D. student who will incorporate these results into his dissertation.
研究人员建议使用自然存在的同位素铍-7作为示踪剂,估计各种微量元素向北冰洋表面的大气通量,铍-7是宇宙射线在大气中产生的,半衰期为53.3天。他们通过与本建议书编写同时进行的国际合作,收集了雪、海冰、地表沃茨和大气气溶胶的样本。该项目为Be-7和微量元素(包括铝、锰、铁、铜、锌、镉和铅)的分析提供资金。许多化学物种进入全球海洋的大气输入量已被证明等于或超过来自河流的输入量。在北极,若干污染元素主要来自大气,对北极生态系统和人类健康产生影响。该项目将调查国际GEOTRACES计划感兴趣的几个要素,该计划目前正在制定协调北极工作的计划。该项目将支持一个博士学位。将把这些结果写进论文的学生。
