A scientist from the University of Miami Rosenstiel School of Marine and Atmospheric Science plans to participate in the 2013 GEOTRACES Eastern Pacific Zonal transect cruise to determine the vertical distribution of dissolved (0.2 µm) iron, manganese, zinc, copper, and cadmium in samples obtained between the East Pacific Rise and Tahiti. In addition, measurements of soluble (10 kilo Daltons) and colloidal iron will be made on all samples collected during the cruise track from Peru to Tahiti. Results from this study will be used to determine the influence of hydrothermal vents on the source and sink of the above mentioned elements and to understand the role of colloid iron in the transport of hydrothermal iron, as well as the cycling of iron in the oligotrophic South Pacific and low oxygen waters near the continental margin off Peru. In terms of the broader impacts, it is anticipated that results from the project will be incorporated into lecture material for classes. One graduate student will be supported and trained as part of this project.

迈阿密罗森斯蒂尔大学海洋与大气科学学院的一名科学家计划参加2013年的地理位置，以确定东太平洋，铁，锰，锌，铜和钙的垂直分布（0.2 µm）的垂直分布（0.2 µm），在东部太平洋上升和Thahiti之间获得的样品中获得的样品。此外，将对从秘鲁到大溪地的巡航轨道期间收集的所有样品进行固体（10公斤达尔顿）和胶体铁的测量。这项研究的结果将用于确定水热通风孔对上述元素的来源和下水道的影响，并了解Coloid Iroid在水热铁的运输中的作用，以及铁在少突平的南太平洋和低氧水域中的循环。就更广泛的影响而言，预计该项目的结果将纳入课堂的演讲材料中。作为该项目的一部分，将为一名研究生提供支持和培训。
