The author reconstructed in-situ volume transport (VT) through the Bering Strait using the NNW wind component, the gradient of dynamic ocean topography (DOT) across the strait and DOT in the East Siberian Sea (RMSE = 0.2 Sv). The difference between in-situ VT and reconstructed VT (diffVT) was correlated with DOT in the northern Bering Sea shelf (DOT_BER) during fall and winter. DOT_BER was then introduced to the multiple linear regression model. The reconstructed VT shows the improved accuracy of reconstruction (RMSE = 0.16). Also, the author found DOT_BER contributes to constant northward transport rather than the variability of in-situ VT. Those suggest that DOT_BER represents a part of the pressure head forcing.

EOF 1st mode of DOT (DOT-EOF1) was correlated with diffVT during fall season. SVD analysis revealed EOF 2nd mode of DOT is related to the Aleutian Low pressure pattern, but DOT-EOF1 is not related to the atmospheric circulation. The author found that positive correlation (R = 0.46) between DOT-EOF1 and the Pacific Decadal Oscillation (PDO). Those suggest that the variability of DOT in the Bering Sea shelf related to the pressure head forcing is considered to be resulted from steric variability.

作者利用NNW风分量，跨海峡的动态海洋地形（DOT）和东西伯利亚海的DOT（RMSE = 0.2 Sv）重建了白令海峡的原位体积运输（VT）。在秋季和冬季，原位VT和重建VT（diffVT）之间的差异与北部白令海陆架（DOT _BER）的DOT相关。然后将DOT _BER引入多元线性回归模型。重建的VT显示出改善的重建精度（RMSE = 0.16）。此外，作者发现DOT _BER有助于持续的向北传输，而不是原位VT的可变性。这些表明，DOT _BER代表了压头压力的一部分。

在秋季，DOT的EOF第一模式（DOT-EOF1）与diffVT相关。SVD分析表明，DOT的EOF第二模式与阿留申低压模式有关，而DOT-EOF1与大气环流无关。作者发现DOT-EOF1与太平洋年代际振荡（PDO）之间呈正相关（R = 0.46）。这些表明，白令海陆架DOT的变化与压头压力有关，被认为是由于空间变化引起的。
