我们使用了一种改进的吸附阴极溶出方波伏安法，以确定在北大西洋西部的三个操作定义的馏分铁的垂直剖面。“溶解铁”（0.4-pm级分）从地表水中的0.1 nM增加到1，000 m以下深度的1.3 nM。我们的研究结果表明，如果我们要了解铁对海洋中浮游植物生产的影响，需要考虑铁及其在海水中的粒度组分的时间变化。
We used an improved adsorptive cathodic stripping square-wave voltametry method to determine vertical profiles of three operationally defined fractions of iron in the western North Atlantic Ocean. “Dissolved Fe” ( 0.4-pm fraction) increased from 0.1 nM in the surface water to 1.3 nM at depths below 1,000 m. Our results suggest the need to consider the temporal variation of iron and its size fractions in seawater if we are to understand the influence of iron on phytoplankton production in the ocean.
