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.

美国GEOTRACES北大西洋分区巡航定于2010年10月15日至12月5日进行。由于该船的推进系统出现重大且无法解决的机械故障，该探险队在完成大约三分之一后，不得不于11月4日在佛得角群岛终止计划的轨道。 这需要对所有出海调查人员的回程以及所有样品和设备的运输安排进行现场更改。 该提案中要求的资金解决了 PI 需要支付为邮轮做准备的工资费用以及将物资运送到船上并在邮轮结束后返回其所在机构的运输费用的需要。 作为本研究的一部分确定的溶解和胶体微量元素（Cd、Fe、Mn 和 Zn）将改善耦合海洋/大气碳和营养物循环模型，并产生关于大气在将金属沉积到地表水和海洋中的作用的新见解。它们转移到内海。
