Collaborative Research: GEOTRACES Atlantic Section: Mercury Speciation Along a Zonal Section in the North Atlantic

美国GEOTRACES北大西洋区域巡航计划于2010年10月15日至12月5日进行。由于船的推进系统出现了无法解决的重大机械故障，11月4日，在完成了大约三分之一的计划航程后，探险队不得不在佛得角群岛终止。这就需要对所有海上调查人员的返回行程以及所有样品和设备的运输安排进行现场调整。本提案中所要求的资金用于满足pi参与2011年秋季北大西洋部分继续巡航所需的工资、旅行、航运和用品。这位来自赖特州立学院的科学家要求一个月的暑期工资来准备和参加这次巡航。旅行资金将确保科学家们能够在航行结束后返回他们的家庭机构，运输费用将用于将设备和物资运送到船上并返回他们的机构，以及在船返回港口后遣散船。考虑到进行汞分析所需的一些物资是时间敏感的和过期的，需要资金来替换第二站巡航的一些物资。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积累的理解。

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.
