AEROCE Network Studies - Phase II: Trace Metals in North Atlantic Precipitation; Atmospheric Source and Oceanic Fate

降水将作为北大西洋AEROCE网络第二阶段的一部分进行收集，并对痕量金属Al、Cd、Cr、Cu、Fe、Mn、Pb和Zn进行分析。其目的是：(1)描述北大西洋大气的痕量金属化学特征；(2)评估大陆排放的痕量金属对大气化学过程的影响，以及其沉积对北大西洋生物地球化学循环的影响。具体而言，这些数据将用于：(1)确定北大西洋周围大陆痕量金属排放的来源和通量，以及(2)评估大陆衍生的痕量金属对海水生物地球化学过程的沉积和影响。

Precipitation will be collected as part of Phase II of the AEROCE network in the North Atlantic and analyzed for the trace metals Al, Cd, Cr, Cu, Fe, Mn, Pb, and Zn. The purpose is to; (1) characterize the trace metal chemistry of North Atlantic atmosphere, and (2) assess the impact of continental emissions of trace metals on atmospheric chemical processes, as well as the impact of their deposition on biogeochemical cycles in the North Atlantic Ocean. Specifically the data will be used to; (1) determine the source and flux of trace metal emissions from continents surrounding the North Atlantic, and (2) evaluate the deposition and impact of continentally derived trace metals on biogeochemical processes of seawater.
