本文提出了第一次估计的季节循环的海洋和海冰的热量和淡水（FW）通量的北冰洋边界。海洋运输估计主要使用138停泊仪器部署在2005年9月至2006年8月在四个主要的北极门户：戴维斯，弗拉姆，白令海峡，和巴伦支海开口（BSO）。海冰输运是由海冰同化产物估算的。月速度场的计算与盒逆模型，强制执行质量和盐守恒。在此期间，四个关口的体积输送量（年平均值± 1标准差）分别为戴维斯海峡为-2.1 ± 0.7 Sv，弗拉姆海峡为-1.1 ± 1.2 Sv，BSO为2.3 ± 1.2 Sv，白令海峡为0.7 ± 0.7 Sv（1 Sv <$106m3s −1）。由此得到的海洋和海冰热量和FW通量分别为175 ± 48 TW和204 ± 85 mSv。这些边界通量准确地代表了相关地表通量的年平均值。海洋热传输变率来自大西洋水层的速度变率和水柱上部的温度变率。白令海峡流速变率对海洋FW输送的变率起主导作用。北极的净水团转变意味着流入的沃茨的盐度和温度分别降低了0.62 ± 0.23 ° C和3.74° ± 0.76°C，密度降低了0.23 ± 0.20 kg m−3。边界热量和FW通量提供了一个基准数据集的数值模式和大气再分析产品的验证。
This paper presents the first estimate of the seasonal cycle of ocean and sea ice heat and freshwater (FW) fluxes around the Arctic Ocean boundary. The ocean transports are estimated primarily using 138 moored instruments deployed in September 2005–August 2006 across the four main Arctic gateways: Davis, Fram, and Bering Straits, and the Barents Sea Opening (BSO). Sea ice transports are estimated from a sea ice assimilation product. Monthly velocity fields are calculated with a box inverse model that enforces mass and salt conservation. The volume transports in the four gateways in the period (annual mean ± 1 standard deviation) are −2.1 ± 0.7 Sv in Davis Strait, −1.1 ± 1.2 Sv in Fram Strait, 2.3 ± 1.2 Sv in the BSO, and 0.7 ± 0.7 Sv in Bering Strait (1 Sv ≡ 106m3s−1). The resulting ocean and sea ice heat and FW fluxes are 175 ± 48 TW and 204 ± 85 mSv, respectively. These boundary fluxes accurately represent the annual means of the relevant surface fluxes. The ocean heat transport variability derives from velocity variability in the Atlantic Water layer and temperature variability in the upper part of the water column. The ocean FW transport variability is dominated by Bering Strait velocity variability. The net water mass transformation in the Arctic entails a freshening and cooling of inflowing waters by 0.62 ± 0.23 in salinity and 3.74° ± 0.76°C in temperature, respectively, and a reduction in density by 0.23 ± 0.20 kg m−3. The boundary heat and FW fluxes provide a benchmark dataset for the validation of numerical models and atmospheric reanalysis products.
