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.

来自迈阿密大学罗森斯蒂尔海洋和大气科学学院的一名科学家计划参加2013年GEOTRACES东太平洋带状断面巡航，以确定东太平洋隆起和塔希提岛之间获得的样品中溶解（0.2 µm）铁，锰，锌，铜和镉的垂直分布。 此外，还将对从秘鲁到塔希提岛的巡航航线上收集的所有样品进行可溶性（10千道尔顿）和胶态铁的测量。这项研究的结果将用于确定热液喷口对上述元素的源和汇的影响，并了解胶体铁在热液铁运输中的作用，以及铁在贫营养南太平洋和秘鲁大陆边缘附近低氧沃茨的循环。 就更广泛的影响而言，预计该项目的成果将纳入课堂教材。 一名研究生将作为该项目的一部分得到支持和培训。
