Concentrations, Sources, and Air-to-Sea Transfer of Trace Elements in the Atmosphere over the North Pacific Ocean

拟议研究的主要目标是确定1986年两次巡航期间从北太平洋西风风场采集的大气样品中痕量元素的浓度。在两次航行中采集了大量的气溶胶和降水样本，这是该地区唯一一套广泛的高质量微量元素样本。还将完成对从南太平洋气溶胶采样站网络收集的大气样本的分析。将特别强调将这些分析的结果与先前补充研究的数据结合起来。数据解释将涉及北太平洋西风带和太平洋其他三个地面风区的微量元素和矿物气溶胶浓度、来源和通量之间的比较和对比。

The primary goal of the proposed research is to determine the concentrations of trace elements in atmospheric samples that were collected from the westerly wind field over the North Pacific Ocean during two cruises in 1986. Numerous aerosol and precipitation samples were collected during the two cruises, and this is the only extensive set of high-quality trace element samples from the region. The analysis of atmospheric samples that were collected from a network of aerosol sampling stations in the South Pacific will also be completed. Special emphasis will be placed on integrating the results of these analyses with data from prior complementary studies. Data interpretation will involve comparisons and contrasts among the trace element and mineral aerosol concentrations, sources, and fluxes in the North Pacific westerlies and in the three other surface-level wind regimes over the Pacific.
