RAPID: Participation in October 2011 US GEOTRACES North Atlantic Zonal Section Continuation Cruise

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一名研究生的费用，并为他参加定于2011年秋季继续进行的北大西洋部分航行购买用品。为研究生提供的额外资金将用于第二次航行的准备工作，而用品申请是为了补充第一次航行中损失的用品。 拟议的研究将大大提高我们对微量元素跨界交换以及大气输入对海洋化学影响的认识。

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 PI's need to cover a graduate student and purchase supplies associated with his participation in the continuation of the North Atlantic section cruise scheduled for autumn 2011. The additional funds for the graduate student would cover the effort to prepare for a second cruise whereas the supply request is to replace those lost during the first cruise. The proposed research would significantly improve our knowledge of cross margin exchange of trace elements, as well as the impact of atmospheric inputs on ocean chemistry.
