Collaborative Research: Eurasian and Makarov basins observational network targets changes in the Arctic Ocean

为响应对了解北冰洋高纬度气候快速变化的长期多学科观测系统的迫切需求，提出了欧亚和马卡罗夫盆地（EMB）观测网络作为北极观测网络（AON）的一个组成部分。将进行三次8月至9月的巡航，每两年一次，沿着大陆边缘，边界电流管道进行广泛的测量；游轮将覆盖从斯瓦尔巴群岛到东西伯利亚海的广大地区。该项目利用系泊、重复的海洋剖面和拉格朗日漂流器，将海洋学、化学和冰观测结合在一起，提供有关北冰洋变化的重要信息。作为一个AON元素，本研究的总体目标是编制一个关于大西洋水（AW）在欧洲大陆架中状态和转变的有凝聚力的图片，特别关注三个主要观测目标：(1)边界流沿坡输送大西洋水(2)大西洋水分支与大陆架水、深盆地内部和上层海洋的相互作用(3)欧洲大陆架中上层海洋环流变化的指示。提出的目标范围广泛，对现代高纬度观测海洋学提出了广泛的挑战。EMB的大小和位置意味着北冰洋的这一部分是泛北极条件和过程的代表，因此适合长期观测。因此，该项目是泛aon的重要组成部分。研究生将获得资助；鼓励女性和阿拉斯加原住民学生参加。项目扩展将在2013年以船上暑期学校达到高潮。根据AON数据政策，将提供北极卫星海冰和高度计测量急需的基准数据和产品。

Responding to urgent needs for a long-term multidisciplinary observation system for understanding rapid high-latitude climate change in the Arctic Ocean, a Eurasian and Makarov Basin (EMB) observational network is proposed as an element of the Arctic Observing Network (AON). Three August-September cruises, one every two years, will be conducted, with extensive measurements along continental margins, a boundary current conduit; cruises will cover vast areas from Svalbard to the East Siberian Sea. The program ties together oceanographic, chemical, and ice observations using moorings, repeated oceanographic sections, and Lagrangian drifters to provide vital information about Arctic Ocean changes. The overarching goal of the study as an AON element is to compile a cohesive picture of the state and transformations of Atlantic Water (AW) in the EMB, with particular focus on three major observational targets: (1) along-slope AW transport by the boundary currents (2) interaction of AW branches with shelf waters, deep basin interior and upper ocean (3) EMB indications of changes in the upper ocean circulation. The proposed targets are broad in scope and pose a wide range of challenges to modern high-latitude observational oceanography. The EMB's size and location mean that this part of the Arctic Ocean is representative of pan-arctic conditions and processes, and therefore appropriate for long-term observing. Therefore, the project is an important element of the pan-AON. Graduate students will be supported; female and Alaska Native students will be encouraged to participate. Program outreach will culminate in 2013 with a shipboard summer school. Data and products, critically-needed benchmarks for Arctic satellite sea-ice and altimeter measurements, will be available per AON data policy.
