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满足 PI 所需的工资、旅行、运输和供应品，这些费用与他们参加计划于 2011 年秋季继续进行的北大西洋航段航行相关。莱特州立学院的科学家要求获得一个月的夏季工资准备并参加巡航。 旅行资金将确保科学家们能够在航行结束时返回他们的家乡机构，运输费用将把设备和物资运送到船上并运回他们的机构，以及在船返回港口后将其复员。 鉴于进行汞分析所需的一些用品对时间敏感并且会过期，因此需要资金来更换航行第二段的一些用品。 为这次航行计划的汞测量将大大加深我们对这种元素如何在海洋中循环和在鱼类中生物累积的理解。
