The freshwater export from the Arctic Ocean to the North Atlantic occurs in several locations, including large volumes of low-salinity water leaving the Fram Strait and the Canadian Archipelago, continuing south along the east (and then west) Greenland and through the Baffin Bay and then along the Labrador Peninsula. Similarly, smaller volumes of freshwater leave the western Barents Sea along the Spitsbergen coast. These coastal currents, limited by the shelf breaks, and co-existing with the recirculating Atlantic water, play an important role in the Arctic Ocean water mass budget. They are, however, difficult to survey on a year-round basis, as they are often covered with fast and drifting sea ice. Moorings are deployed rarely there and cannot reach the uppermost surface layer. Nevertheless, long-term time series from various research surveys, data from tagged marine mammals, surface drifters and Voluntary Observing Ships do exist in global databases, even if full shelf area coverage and/or winter measurements are scarce or missing. This work attempts to understand the similarities and differences between these two special Arctic-related current systems, based on the available observations.

Please note the venue  (Ray Beverton (044/11)) is not the usual room.
