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

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。本提案请拨的经费用于支付一名研究生的费用，并购买与他参加定于2011年秋季继续进行的北大西洋段巡航有关的用品。研究生的额外资金将用于为第二次邮轮做准备，而补给申请是为了弥补第一次邮轮期间损失的资金。拟议的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的影响的了解。

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 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.
