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 a graduate student, travel, and supplies costs associated with his participation in the continuation of the North Atlantic section cruise scheduled for autumn 2011. Graduate student and travel support are needed to ensure a student at the University of Southern California can participate in the conclusion of the cruise and collect samples to finish his dissertation. Additional travel costs are included to demobilize the ship at the end of the cruise. Funds for supplies replace those lost during the initial leg of the cruise. At the end of this project, the relationship between Cu cycling and its speciation over a wide range of oceanographic regimes will be documents, as well as the influence of this element on the community structure of Prochlorococcus at the eco-type level.

美国GEOTRACES号北大西洋区域段巡航定于2010年10月15日至12月5日进行。 由于船舶推进系统出现无法解决的重大机械故障，探险队不得不在完成约三分之一的计划轨道后于11月4日在佛得角群岛终止。 这就需要对所有海上调查员的回程旅费以及所有样品和设备的运输安排进行现场更改。 本提案中请求的资金满足了PI支付研究生、旅行和与他参加计划于2011年秋季继续进行的北大西洋部分巡航相关的用品费用的需求。 需要研究生和旅行支持，以确保南加州大学的学生能够参与游轮的结束并收集样本以完成他的论文。 还包括在巡航结束时遣散船只的额外旅费。 供应品资金将弥补航行初期损失的资金。 在这个项目的最后，铜循环和它的形态之间的关系，在广泛的海洋学制度，以及这种元素对原绿球藻群落结构的影响，在生态类型的水平将文件。
