[1]白令海研究了双日代际变化，特别是在靠近阿留申山口的东南部盆地，那里由于日涨潮，垂直混合可能很强。在该地区发现的这些变化与18.6年周期的潮汐周期同步，并且时间模式与先前研究报道的靠近千岛海峡的亚北极太平洋西北部的时间模式相似。在日潮较强的时期，上层盐度和密度较高。中间层层厚大，同时期等平势温度和视氧利用率较低。结果表明，这些变化与垂直混合的节点调制所期望的模式一致，并且一个简单的二维模型，假设异常垂直混合和平均电流平流之间的平衡，在一定程度上成功地解释了上层盐度和中层等平温度以及中间层表观氧利用的变化。
[1] Bidecadal variations are investigated in the Bering Sea, especially in the southeastern basin adjacent to the Aleutian passes, where vertical mixing may be strong because of the diurnal tide. Those variations found in this region are synchronized with the 18.6 year period nodal tidal cycle, and the temporal patterns are similar to ones around the northwestern subarctic Pacific near the Kuril Straits reported by a previous study. Salinity and density in the upper layer are high in the periods when the diurnal tide is strong. In the intermediate layer, layer thickness is large, and isopycnal potential temperature and apparent oxygen utilization are low in the same periods. It is shown that these variations are consistent with the patterns expected from the nodal modulation of vertical mixing, and a simple two-dimensional model, assuming a balance between anomalous vertical mixing and advection of anomaly by the mean current, succeeds to some extent in explaining the variations of the upper layer salinity and isopycnal temperature and apparent oxygen utilization in the intermediate layer.
