Isotopic compositions of lead will be measured in different sized particles collected on stages of cascade impactor samples of air which have already been collected in the South Pacific and North Pacific westerlies as part of the SEAREX Program. These data will be combined with SEAREX data for lead, salt and dust concentrations measured in rain, air, and sea water samples associate with the impactor samples to provide a reliable explanatory model for enrichment of lead in sea salts and will furnish trustworthy estimates of magnitures of recycled eolian lead fluxes entering the oceans.

铅的同位素组成将在不同大小的颗粒中进行测量，这些颗粒是通过级联撞击器收集的，空气样本已经在南太平洋和北太平洋西风带收集，作为SEAREX计划的一部分。这些数据将与SEAREX在雨水、空气和与撞击器样本相关的海水样本中测量的铅、盐和粉尘浓度数据相结合，为海盐中铅的富集提供可靠的解释模型，并将提供进入海洋的风成铅通量的可靠估计。
