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。 本提案中要求的资金用于解决 PI 需要支付的研究生费用、旅行费用以及与参加计划于 2011 年秋季继续进行的北大西洋航段航行相关的用品费用。需要研究生和旅行支持以确保学生南加州大学的博士生可以参加这次航行的结束并收集样本来完成他的论文。 额外的旅行费用包括在航行结束时遣返船只的额外旅行费用。 补给资金弥补了航程首段期间损失的资金。 在该项目结束时，将记录铜循环及其在各种海洋学状况下的物种形成之间的关系，以及该元素对生态类型水平上原绿球藻群落结构的影响。
