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 PIs need to cover salary, travel, shipping, and supplies associated with their participation in the continuation of the North Atlantic section cruise scheduled for autumn 2011. The scientist from Wright State College requests one month of summer salary to prepare and participate in the cruise. Travel funds will ensure the scientists can return to their home institutions at the end of the cruise and shipping costs will get the equipment and supplies to the ship and back to their institutions, as well as demobilize the ship once it returns to port. Given that some of the supplies needed to carry out mercury analysis are time sensitive and expire, funds are needed to replace some of the supplies for the second leg of the cruise. The proposed mercury measurements planned for this cruise would significantly further our understanding of how this element cycles in the ocean and bioaccumulates in fish.

美国的地理位置北大西洋地区区域定于2010年10月15日至12月5日。由于该船的推进系统发生了重大不可抵御的机械故障，因此必须在11月4日在佛得角群岛终止该探险队在完成计划的赛道大约三分之一后。 这需要对所有乘船研究人员以及所有样品和设备的运输安排进行返回旅行的现场变化。 本提案中要求的资金解决了PI所需的资金需要涵盖与他们参与计划于2011年秋季进行的北大西洋区巡游有关的薪水，旅行，运输和用品。赖特州立大学的科学家要求夏季薪水的一个月薪水准备和参与巡航。 旅行资金将确保科学家可以在巡航结束时返回其家庭机构，运输成本将使船上的设备和物资返回其机构，并在船只返回港口后使其复员。 鉴于进行汞分析所需的一些供应是对时间敏感和到期的，因此需要资金来替换巡航第二回合的一些耗材。 为此巡航计划的拟议的汞测量结果将大大进一步了解我们对这一元素在海洋中循环和生物蓄积如何在鱼类中循环的理解。
