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

已经制定了国际地球物理轨道系统方案，以产生一个关键微量元素和同位素的全球框架，该框架将描述这些特性在海洋中的当代分布。然后，这些信息可用于限制生物地球化学重要元素的过程和通量的模型，以及框定通量过程和转化的关键示踪剂。伍兹霍尔海洋研究所的一名科学家计划参加2010年前往北大西洋的GEOTRACES邮轮，并测量表层样品和整个水柱中的钴(Co)和钴的形态。样品将来自影响痕量金属及其同位素的所有物理和生物地球化学过程，即强烈的经向平流、边界清除和来源、风沙沉积以及地中海和拉布拉多海的中间水输入。由此产生的数据集应该提供对这种元素的来源、汇和化学形态的洞察。这项研究将极大地促进海洋环境中存在的少量钴数据，并提供对钴生物地球化学的更多了解。在教育影响方面，这项研究将为博士后研究人员和研究生提供支持。

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.
