The influence of Arctic freshwater export on the North Atlantic circulation
Arctic freshwater has the potential to influence the North Atlantic circulation through its impact on stratification and hence deep covection. Freshwater export is accomplished through two major gateways, the Canadian Arctic Archipelago (CAA) and Fram Strait. In this modelling study we show that the...
