This award is for support for a project to develop long-term records of the atmospheric deposition of aerosol-borne, marine- derived elements to the Antarctic ice sheet. The project includes the sampling of Antarctic ice core samples from the Vostok ice core and the laboratory analysis of soluble ions in the ice. The analyses include methanesulfonate, non-sea-salt sulfate, and several additional ions derived from gaseous emissions from the sea surface, from seasalt, and associated with continental dust. The principal emphasis of this work is on sulfur, because of its role as a major aerosol-forming constituent of the atmosphere, and its potential importance to climate. The main goal of the project is to complete analyses of the Vostok ice core.

该奖项是为了支持一个项目，开发长期记录大气沉积的气溶胶，海洋衍生元素到南极冰盖。 该项目包括从东方冰芯中采集南极冰芯样品，并对冰中的可溶离子进行实验室分析。 分析包括甲烷磺酸盐，非海盐硫酸盐，和其他几个离子来自气体排放从海面，从海盐，并与大陆尘埃。这项工作的主要重点是硫，因为它作为大气中主要的气溶胶形成成分的作用，以及它对气候的潜在重要性。 该项目的主要目标是完成对东方号冰芯的分析。
