A two-decade-long accumulation of freshwater in the Arctic Ocean’s Beaufort Gyre has recently started to be released. Here we use satellite observations and model simulations to show that changes in wind regimes and sea ice declines are causing freshwater to accumulate close to the export gateways to the North Atlantic. This emerging buffer zone plays an important role in modulating the propagation of freshwater into the subpolar North Atlantic.

在缓冲区内转移到北大西洋的北极淡水异常延迟

北冰洋博福特环流长达二十年的淡水积累最近开始释放。在这里，我们使用卫星观测和模型模拟来表明，风态的变化和海冰的减少导致淡水在北大西洋出口门户附近积累。这个新兴的缓冲区在调节淡水向亚极地北大西洋的传播方面发挥着重要作用。
