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

这项研究的主要目的是确定 大气样品中微量元素的浓度 从北方的西风场收集到的数据 1986年，两次巡航太平洋。 大量的气雾剂和 在两次航行期间收集了降水样本， 这是唯一一套完整的高质量痕迹 该地区的元素样本。 大气分析 从一个气溶胶采样网络中收集的样本 南太平洋的基地也将建成。 特别 重点将放在整合这些成果上， 与先前补充研究的数据进行分析。 数据 解释将涉及比较和对比之间的 微量元素和矿物气溶胶浓度、来源和 在北太平洋西风带和其他三个通量 太平洋上空的表面风态。

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.
