A CTD/Hydrographic Section Across the Arctic Ocean

9322546该奖项进行的Aagaard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。这一具体的研究项目包括水文学方案的一部分。精确的温度、电导率、氧气和营养分布将沿着巡航轨道每隔一段时间进行收集。将对产生的数据进行分析，以增加对北冰洋结构和环流的了解。研究将侧重于三个领域：1)盐碱的结构，其中大量海水之间的密度差异可能推动北冰洋深层水与来自世界其他海洋部分的水的循环和混合；2)主要海底地貌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. ***
