A CTD/Hydrographic Section Across the Arctic Ocean

9322705由该奖项进行的SWIFT研究是1994年美国/加拿大北冰洋部分的一部分。AOS是与加拿大的一项合作努力，约有60名科学家参加了1994年夏天为期55天的野外项目，其中包括一艘加拿大破冰船和一艘美国破冰船。AOS由北极系统科学全球变化研究计划赞助，研究由海洋科学部、极地方案办公室和海军研究办公室(ONR)联合赞助。收集的数据应有助于增进我们对北极如何成为不断变化的全球气候条件的指标以及它如何影响较温和海洋和区域的物理、化学和生物特征的理解。该项目包括一项服务和研究计划。斯克里普斯海洋研究所的海洋数据设施将进行一项详细的水文调查，包括沿邮轮航道以大约30公里的间隔进行大约100个精确的温度、电导率、氧气和营养剖面。结果数据将与所有参与者共享。SWIFT将利用水文数据重点研究北冰洋及其附近海域中、深水的来源和循环。待确定的参数是物理化学性质的自上而下的分布和来源，以及次表层边界流的位置、来源和结构。这样获得的信息将补充AOS期间的其他研究，并将有助于研究这些制度对环境强迫的反应。***

9322705 Swift Research conducted by this award is a component of the 1994 U.S./Canada Arctic Ocean Section (AOS). The AOS is a collaborative effort with Canada that involves approximately 60 scientists participating on a Canadian and a U.S. icebreaker during a 55-day field program in the summer of 1994. The AOS is under the auspices of the Arctic Systems Science (ARCSS) Global Change Research Program and research is jointly sponsored by the Division of Ocean Sciences, the Office of Polar Programs and Office of Naval Research (ONR). Data collected should be relevant to improving our understanding of how the Arctic is an indicator of changing global climate conditions and how it affects the physical, chemical, and biological features of the more temperate oceans and regions. This project encompasses a service and research program. The Oceanographic Data Facility (ODF) at the Scripps Institution of Oceanography will conduct a detailed hydrographic survey consisting of about 100 precision temperature, conductivity, oxygen, and nutrient profiles at approximately 30 km intervals along the cruise track. Resulting data will be shared with all participants. Swift will use the hydrography data to focus on a study of the origin and circulation of the intermediate and deep waters of the Arctic Ocean and nearby seas. Parameters to be determined are the surface-to-bottom distributions and sources of the physical and chemical characteristics, and the location, origin, and the structure of sub-surface boundary currents. Information thus obtained will augment other studies during the AOS and will contribute to studies of the response of the regimes to environmental forcing. ***
