This program focuses on the major aerosol species that are found in the marine atmosphere: nss-SO4=, from anthropogenic sources and biological sources in the ocean; MSA (methanesulfonate), form DMS (dimethyl sulfide) derived from oceanic sources; NO3-, from anthropogenic sources, lightning and the stratosphere; NH4+, from continental and oceanic sources; Na+, from sea salts. We also study (with the University of Rhode Island) the mineral species present in the atmosphere in this region. The major objective is to characterize the distribution of these species over the ocean and to understand the factors that control their concentration; the sources of the species and their temporal and areal variability; the transport paths through the atmosphere and the removal to the ocean.

该计划的重点是主要的气溶胶种类， 在海洋大气中发现：nss-SO 4 =，来自人类活动 海洋中的污染源和生物源 （甲磺酸盐），形成DMS（二甲基硫醚），衍生自 海洋来源; NO3-，来自人为来源，闪电和 平流层; NH 4+，来自大陆和海洋来源; Na+来自海盐。 我们还学习（与罗德岛大学 岛）的矿物物种存在于大气中， 地区 主要目的是描述分布特征 这些物种在海洋上的分布， 控制其浓度;物种的来源， 它们的时间和区域变化;通过 大气层和海洋的迁移。
