This award is for support of a three year project to obtain a long term record of the atmospheric deposition of the marine-derived elements Sulfur, Bromine, Iodine, and Selenium. The principle focus of the work is on the sulfur cycle, because of its role as the major aerosol forming species in the atmosphere and its potential importance in climate regulation. Samples from the Vostok and Taylor Dome ice cores will be analyzed for this study. The ice core record of methansulfonate and non-seasalt sulfate will be extended to include two complete glacial cycles in the deep Vostok ice core and analyses of a shallow, dry drilled ice core from Vostok will allow the identification of any recent changes in these parameters. Analyses of the Taylor glacier ice core will also be made for comparison with Vostok.

该奖项是为了支持一个为期三年的项目，以获得长期的 海洋衍生物大气沉积的长期记录 元素硫、溴、碘和硒。 原则 工作的重点是硫循环，因为它的作用， 大气中形成气溶胶的主要种类及其 在气候调节方面的潜在重要性。 样本 本研究将分析沃斯托克和泰勒穹冰芯。 冰芯记录的甲烷磺酸盐和非海盐硫酸盐将 可以扩展到包括两个完整的冰川循环在深 东方号冰芯和浅干钻取冰芯的分析 将允许识别任何最近的变化， 这些参数。 对泰勒冰川冰芯的分析 也可以与东方号进行比较。
