A composite dataset of 27 moorings across the Chukchi Sea and Bering Strait in 2013–14, along with satellite sea ice concentration data, weather station data, and atmospheric reanalysis fields, are used to explore the relationship between the circulation, ice cover, and wind forcing. We find a clear relationship between northeasterly winds along the northwest coast of Alaska and reversed flow along the length of Barrow Canyon and at a mooring site ∼ 100 km upstream on the northeast shelf. Atlantic Water is frequently upwelled into the canyon during the fall and winter, but is only able to reach the head of Barrow Canyon after a series of long upwelling events. A pair of empirical orthogonal function (EOF) analyses of ice cover reveal the importance of inflow pathways on the pattern of freeze-up and melt-back, and shed light on the relative influence of sensible heat and wind forcing on polynya formation. An EOF analysis of 25 mooring velocity records reveals a dominant pattern of circulation with coherent flow across the shelf, and a secondary pattern of opposing flow between Barrow Canyon and Bering Strait. These are related to variations in the regional wind field.

2013-14年楚科奇海和白令海峡27个系泊点的复合数据集，连同卫星海冰浓度数据、气象站数据和大气再分析场，用于探索环流、冰盖和风之间的关系强迫。我们发现沿阿拉斯加西北海岸的东北风与沿巴罗峡谷长度和东北陆架上游约 100 公里的系泊地点的逆流之间存在明显的关系。大西洋水在秋季和冬季经常上升到峡谷中，但经过一系列长时间的上升流事件后才能够到达巴罗峡谷的顶部。冰盖的一对经验正交函数 (EOF) 分析揭示了流入路径对冻结和融化模式的重要性，并阐明显热和风力对冰穴形成的相对影响。对 25 条系泊速度记录的 EOF 分析揭示了一种主要的环流模式，在大陆架上有相干流，而在巴罗峡谷和白令海峡之间则是逆流的次要模式。这些与区域风场的变化有关。
