The Impact of Wind-Driven Mixing in the Barents Sea

北冰洋的海冰能够将水柱与风力隔绝。结果是北极的混合比世界其他海洋更弱。随着北冰洋逐渐演变成一个季节性的无冰状态，预计开放水域面积的增加将导致北冰洋更大的大气强迫。增加的能量输入可能通过产生内波来增强水柱的混合。更大的内波引起的混合将导致更大的垂直热通量和更大的海冰融化。水柱的其他特性也可能增加垂直通量;特别是营养物，在海冰覆盖减少的情况下，营养物有可能促进更大的生物生产。然而，在北极的内波的许多观测已经在冰覆盖的沃茨，和情节混合事件在开放水域条件下的作用和流行仍然知之甚少。

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.
