Manganese, vanadium, gallium and rare earth elements in the GEOTRACES North Atlantic zonal section

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。GEOTRACES是一个新发起的国际海洋学计划，旨在确定控制海洋中关键微量元素和同位素分布的过程和量化通量，并了解这些分布对不断变化的环境条件的敏感性。在2010年前往北大西洋盆地的GEOTRACES巡航期间，南密西西比大学的一名科学家将确定表面样本和整个水柱中的镓、钒、锰和稀土元素。 将从显示影响痕量金属及其同位素的物理和地球化学过程的地点取样，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的中间沃茨输入。 由此产生的数据集应提供洞察这些元素的跨边缘交换，以及调查氧化还原过程和大气输入。 至于更广泛的影响，该项目将为“我们的海洋世界”提供资金，这是一个每天在包括美国之音在内的数百个广播电台播放的播客。 这项外联工作的目标是向世界各地的听众介绍与海洋事务有关的新闻和信息。 作为该项目的一部分，将支助和培训一名研究生。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). GEOTRACES is a newly initiated international oceanographic program to identify processes and quantify fluxes that control the distributions of key trace elements and isotopes in the oceans and to establish an understanding of the sensitivity of these distributions to changing environmental conditions. During the GEOTRACES cruise to the North Atlantic basin in 2010, a scientist from the University of Southern Mississippi will determine gallium, vanadium, manganese, and rare earth elements in surface samples and throughout the water column. Samples will be taken from sites that exhibit the 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 cross margin exchange of these elements, as well as investigate redox processes and atmospheric inputs. As regards broader impacts, this project would contribute funds for the 'Our Ocean World', a podcast broadcast daily on hundreds of radio stations including the Voice of America. The goal of this outreach effort is to inform listeners around the world about news items and information related to ocean matters. One graduate student would be supported and trained as part of this project.
