On the Link between Arctic Sea Ice Decline and the Freshwater Content of the Beaufort Gyre: Insights from a Simple Process Model

摘要: AbstractRecent satellite and hydrographic observations have shown that the rate of freshwater accumulation in Beaufort Gyre Arctic Ocean has accelerated over past decade. This acceleration coincided with dramatic decline observed sea ice cover, which is expected to modify efficiency momentum transfer into upper ocean. Here, a simple process model used investigate dynamical response changing transfer, its link enhanced freshwater. A linear relationship found between annual mean flux amount accumulated Gyre. In model, both time scale total quantity are determined by balance Ekman pumping an eddy-induced volume toward boundary, highlighting importance eddies adjustment change forcing. When seasonal cycle i...
