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

美国地理跟踪号北大西洋分区巡航计划于2010年10月15日至12月5日举行。由于该船的推进系统发生了无法解决的重大机械故障，探险队在完成了约三分之一的计划航道后，不得不于11月4日在佛得角群岛终止。这需要当场改变所有远洋调查员的回程行程，并改变其所有样品和设备的运输安排。本提案请拨的资金用于支付与参加定于2011年秋季继续进行的北大西洋段邮轮活动有关的薪金、旅费、船费和用品费用。这位来自莱特州立大学的科学家要求一个月的暑期工资来准备和参加邮轮。旅行资金将确保科学家们可以在邮轮结束时返回他们的家乡机构，运费将把设备和补给送到船上并送回他们的机构，以及在船返回港口后遣散。鉴于进行汞分析所需的一些供应品对时间敏感且已过期，需要资金来更换邮轮第二航段的一些供应品。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.
