海洋的温盐环流主要是由北欧海和拉布拉多海的下沉流和整个海洋其余部分的上升流造成的。后者通常被描述为由于破碎的内波。在这里，我们调和的理论和观测估计之间的差异，在深海中的垂直混合提出了一个修订后的观点的温盐环流，它允许额外的上升流在南大洋和分离的北大西洋深水细胞从南极底层水细胞。这些变化也意味着，需要在深海中消散的风能和潮汐能比原先想象的要少得多。
The thermohaline circulation of the ocean results primarily from downwelling at sites in the Nordic and Labrador Seas and upwelling throughout the rest of the ocean. The latter is often described as being due to breaking internal waves. Here we reconcile the difference between theoretical and observed estimates of vertical mixing in the deep ocean by presenting a revised view of the thermohaline circulation, which allows for additional upwelling in the Southern Ocean and the separation of the North Atlantic Deep Water cell from the Antarctic Bottom Water cell. The changes also mean that much less wind and tidal energy needs to be dissipated in the deep ocean than was originally thought.
