Summer 1995 Eastern Arctic Oceanographic Field Studies

9504434该项目将从永久安装在德国破冰研究船Polarstern的船体上的声学多普勒海流剖面仪获得一系列上层海流剖面。 这些数据将于1995年夏季从北冰洋的欧亚海盆获得。 该项目有两个具体目标：测量本底的空间分布和具有足够水平覆盖面的内波切变，以确定内波能的可能来源和消散区域，并记录欧亚盆地内大西洋中层水和北极大陆架改性地表水的分布情况。 由此产生的信息将使我们的理解有实质性的改善，内波，通过剪切诱导湍流，影响北极海洋热收支。 更好地了解北冰洋东部的环流过程，将澄清海洋和全球气候之间的相互作用，并为参数化和调整目前用于研究气候变化的全球环流模型提供所需的信息。 ***

9504434 This project will obtain a series of upper ocean current profiles from the acoustic Doppler current profiler (ADCP) permanently mounted on the hull of the German icebreaking research ship Polarstern. The data will be obtained from the Eurasian Basin of the Arctic Ocean in the summer of 1995. The project has two specific objectives: to measure the spatial distribution of the background and the internal wave shear with sufficient horizontal coverage to identify possible sources and dissipation regions for internal wave energy, and to document the distribution of Atlantic Intermediate Water within the Eurasian Basin and modified surface water on the arctic continental shelf. The resulting information will allow a substantial improvement in our understanding of how internal waves, through shear-induced turbulence, affect the arctic oceanic heat budget. A better understanding of the circulation processes in the eastern Arctic Ocean will clarify interactions between the oceanic and the global climate, and provide information required to parameterize and to tune global circulation models currently being used to study climate change. ***
