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.

为了满足建立长期多学科观测系统以了解北冰洋高纬度气候快速变化的迫切需要，建议将欧亚和马卡罗夫海盆观测网作为北极观测网的一个组成部分。将在8月至9月进行三次巡航，每两年一次，沿沿着大陆边进行广泛测量，这是一个边界电流通道;巡航将覆盖从斯瓦尔巴特群岛到东西伯利亚海的广大地区。该计划将海洋学，化学和冰观测结合在一起，使用系泊，重复海洋学切片和拉格朗日漂流物，以提供有关北冰洋变化的重要信息。 作为AON元素，该研究的总体目标是汇编EMB中大西洋水（AW）的状态和转换的连贯图片，特别关注三个主要观测目标：（1）边界流的沿斜坡AW传输（2）AW分支与陆架沃茨、深盆内部和上层海洋的相互作用（3）上层海洋环流变化的EMB指示。拟议的目标范围广泛，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代表了泛北极的条件和过程，因此适合长期观测。因此，该项目是泛AON的重要组成部分。 研究生将得到支持;女性和阿拉斯加土著学生将被鼓励参加。2013年，该计划的推广将以一个船上暑期学校达到高潮。数据和产品，北极卫星海冰和高度计测量的关键需要的基准，将根据AON数据政策。
