Collaborative Research: GEOTRACES Atlantic Section: Mercury speciation along a zonal section of the North Atlantic

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。 本提案中要求的资金用于支付项目执行人参加定于2011年秋季继续进行的北大西洋部分航行的薪金、差旅、运费和用品。 赖特州立大学的科学家要求一个月的夏季工资，以准备和参加巡航。 旅行资金将确保科学家能够在巡航结束时返回他们的家乡机构，运输费用将使设备和用品到达船上并返回他们的机构，以及在船返回港口后解散船。 鉴于开展汞分析所需的一些供应品具有时间敏感性，而且会过期，因此需要资金来更换巡航考察第二段的一些供应品。 为这次航行计划的拟议汞测量将大大加深我们对这种元素如何在海洋中循环和如何在鱼类中生物积累的了解。

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.
