Collaborative Research: GEOTRACES Atlantic Section, shipboard shore-based determination of key trace elements

美国地理跟踪号北大西洋分区巡航计划于2010年10月15日至12月5日举行。由于该船的推进系统发生了无法解决的重大机械故障，探险队在完成了约三分之一的计划航道后，不得不于11月4日在佛得角群岛终止。这需要当场改变所有远洋调查员的回程行程，并改变其所有样品和设备的运输安排。这项提案中要求的资金解决了PI需要支付准备邮轮的工资费用和邮轮后将他的补给送到船上并返回他的家乡机构的运费。作为这项研究的一部分，所确定的溶解和胶体微量元素(Cd、Fe、Mn和Zn)将改进海洋/大气碳和营养循环耦合模型，并对大气在向表层水域沉积金属及其向海洋内部转移方面的作用产生新的见解。

The U.S. GEOTRACES North Atlantic zonal section cruise was scheduled for 15 October through 5 December 2010. Because of a major irresolvable mechanical failure of the ship's propulsion system, the expedition had to be terminated in the Cape Verde Islands on 4 November after completing about one third of the planned track. This required on-the-spot changes in return travel for all sea-going investigators as well as in shipping arrangements for all their samples and equipment. The funds requested in this proposal address the PI's need to cover salary costs to prepare for the cruise and shipping costs to get his supplies to the ship and back to his home institution after the cruise. The dissolved and colloidal trace elements determined as part of this study (Cd, Fe, Mn, and Zn) would improve coupled ocean/atmosphere carbon and nutrient cycling models and yield new insights on the role of the atmosphere in depositing metals to surface waters and their transfer to the interior ocean.
