Potential positive feedback between Greenland ice sheet melt and Baffin Bay heat content on the west Greenland shelfDownload
Greenland ice sheet meltwater runoff has been increasing in recent decades, especially in the southwest and the northeast. To determine the impact of this accelerating meltwater flux on Baffin Bay, we examine eight numerical experiments using an ocean-sea ice model: Nucleus for European Modelling...
The influence of high-frequency atmospheric forcing on the circulation and deep convection of the Labrador SeaDownload
The influence of high-frequency atmospheric forcing on the circulation of the North Atlantic Ocean with emphasis on the deep convection of the Labrador Sea was investigated by comparing simulations of a coupled ocean–ice model with hourly atmospheric data to simulations in which the...
Recent increases in Arctic freshwater flux affects Labrador Sea convection and Atlantic overturning circulationDownload
The Atlantic Meridional Overturning Circulation (AMOC) is an important component of ocean thermohaline circulation. Melting of Greenland’s ice sheet is freshening the North Atlantic; however, whether the augmented freshwater flux is disrupting the AMOC is unclear. Dense Labrador Sea Water (LSW),...

Accelerating since the early 1990s, the Greenland Ice Sheet mass loss exerts a significant impact on thermohaline processes in the sub-Arctic seas. Surplus freshwater discharge from Greenland since the 1990s, comparable in volume to the amount of freshwater present during the Great Salinity...
