The Impact of Wind-Driven Mixing in the Barents Sea

北冰洋的海冰能够使水柱不受风的影响。结果是，北极的混合比世界其他海洋的混合要弱。随着北冰洋逐渐演变为季节性无冰状态，预计开阔水域面积的增加将导致北冰洋更大的大气作用力。增加的能量输入很可能通过内波的产生增强水柱的混合。更大的内波引起的混合将导致热的垂直通量增强和海冰的更大融化。其他水柱性质也可能看到增强的垂直通量；特别是营养物，在海冰覆盖减少的情况下，营养物有可能推动更大的生物生产。然而，对北极内波的许多观测都是在冰雪覆盖的水域进行的，对开放水域条件下偶发性混合事件的作用和普遍程度仍然知之甚少。

Sea ice in the Arctic Ocean is capable of isolating the water column from wind forcing. The result is that mixing is weaker in the Arctic than in the rest of the world's oceans. As the Arctic Ocean evolves to a seasonally more ice-free state, it is anticipated that the increased area of open water will lead to larger atmospheric forcing of the Arctic Ocean. The increased energy input is likely to enhance mixing through the water column via the generation of internal waves. Greater internal wave-induced mixing will lead to enhanced vertical flux of heat and greater melting of sea ice. Other water column properties are also likely to see enhanced vertical fluxes; notably nutrients, which have the potential to fuel greater biological production under reduced sea ice cover. However, many of the observations of internal waves in the Arctic have been made in ice covered waters, and the role and prevalence of episodic mixing events in open water conditions remain poorly understood.
