English Abstract:
Enhanced transport of low salinity water from the Arctic, as well as the Greenland ice cap, is expected to have impacts on the stratification, water formation and circulation in the North Atlantic Ocean. In this presentation, pathways of freshwater in the Canadian Arctic Archipelago, Baffin Bay and the sub-polar North Atlantic Ocean will be examined. Both observational data and numerical modelling will be used. Observational analyses will focus on the Labrador Current where historical sections will be used to estimate freshwater transport, its variability and locations of offshore exchange. The modelling analysis will be based on regional configurations using the NEMO model of the Arctic Ocean, Canadian Arctic Archipelago and the sub-polar North Atlantic. The impact of freshwater input from the Greenland Ice sheet on the circulation and properties of Baffin Bay will be examined. Lagrangian float tools such as Ariane will also be used to examine the pathways for freshwater from both the Arctic as well as the Greenland Ice sheet into the sub-polar North Atlantic in high resolution simulations.
