GEOTRACES Atlantic Section: Total Dissolved Cobalt and Cobalt Speciation in the North Atlantic

国际GEOTRACES计划的目的是建立一个关键微量元素和同位素的全球框架，以描述这些属性在海洋中的当代分布。这些信息可以用来约束地球化学重要元素的过程和通量模型，以及框架通量过程和转换的关键示踪剂。 伍兹霍尔海洋学研究所的一名科学家计划参加2010年前往北大西洋的GEOTRACES巡航，并测量表面样本和整个水柱中的钴（Co）和Co形态。 将从影响痕量金属及其同位素的所有物理和地球化学过程中取样，即强对流、边界清除和来源、风成沉积以及地中海和拉布拉多海中间沃茨的输入。 由此产生的数据集应提供洞察的来源，汇和化学形态的这一元素。这项研究将极大地有助于海洋环境中钴的少量数据，并提供对钴地球化学的更好理解。在教育影响方面，本研究将为一名博士后研究员和一名研究生提供支持。

The international GEOTRACES program has been developed to produce a global framework of key trace elements and isotopes that will describe the contemporary distributions of these properties in the ocean. This information can then be used to constrain models of the processes and fluxes of biogeochemically important elements and key tracers that frame flux processes and transformations. A scientist from Woods Hole Oceanographic Institution plans to participate in the 2010 GEOTRACES cruise to the North Atlantic and measure cobalt (Co) and Co speciation in surface samples and throughout the water column. Samples will be taken from all physical and biogeochemical processes that influence trace metals and their isotopes, namely strong meridional advection, boundary scavenging and sources, aeolian deposition, and input of intermediate waters from the Mediterranean and Labrador Seas. The resultant dataset should provide insight into the sources, sinks and chemical speciation of this element. This research will greatly contribute to the small amount of data that exists on cobalt in the marine environment and provide a greater understanding of cobalt biogeochemistry. In regard to educational impacts, this research will provide support for a post-doctoral researcher as well as a graduate student.
