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

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。本提案中要求的资金用于解决PI需要支付研究生的费用，并购买与他参加北大西洋部分续订于2011年秋季巡航有关的用品。研究生的额外资金将覆盖准备第二次巡航的努力，而供应请求是替换在第一次巡航中损失的那些。该研究将大大提高我们对微量元素跨边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.
