A CTD/Hydrographic Section Across the Arctic Ocean

由该奖项进行的研究是1994年美国/加拿大北冰洋部分（AOS）的一个组成部分。AOS是一项与加拿大合作的项目，大约有60名科学家参加了1994年夏天一艘加拿大和一艘美国破冰船为期55天的实地项目。AOS在北极系统科学（ARCSS）全球变化研究计划的支持下，研究由海洋科学部、极地项目办公室和海军研究办公室（ONR）联合赞助。所收集的数据应该与提高我们对北极如何成为全球气候条件变化的一个指标以及它如何影响温带海洋和地区的物理、化学和生物特征的理解有关。这个具体的研究项目包含了水文学项目的一部分。精确的温度，电导率，氧气和营养资料将收集沿巡航轨道的间隔。结果数据将被分析，以增加对北冰洋结构和环流的了解。研究将集中在三个方面：1)盐盐的结构，其中海水质量之间的密度差异可能驱动环流和北冰洋深层水与世界其他海洋的水的混合；2)主要海底特征附近的海水性质和梯度；3)1500米以下水柱的水平和垂直结构。＊＊＊

9322546 Aagaard 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 under- standing 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 specific research project encompasses part of the hydrography program. Precision temperature, conductivity, oxygen, and nutrient profiles will be collected at intervals along the cruise track. Resulting data will be analyzed to increase understanding of the structure and circulation of the Arctic Ocean. Research will focus on three areas: 1) the structure of the halocine, wherein density differences between masses of seawater may drive the circulation and mixing of deep Arctic Ocean water with water from other parts of the world's oceans; 2) seawater properties and gradients near major seafloor features, and 3) the horizontal and vertical structure of the water column below 1500 meters. ***
