We hypothesize that when the TPD was deflected westward along northern Greenland, wood was delivered widely to the Canadian Arctic Archipelago; when the TPD exited entirely through Fram Strait via the East Greenland Current, little or no wood was delivered to most of the archipelago, but some continued into Baffin Bay via the West Greenland Current.
Most of this freshwater is exported to the Atlantic as sea ice, about 70% via the East Greenland Current and 30% via the Canadian Arctic Archipelago and the Baffin Current (Arctic System Science, 1990).
Flow out of Baffin Bay contributes to the offshore part of the Labrador Current, which is nearer to the convective area; that water comes from the Arctic Ocean through the channels of the Canadian Archipelago and from the
East Greenland Current. The largest salinity fluctuations on time scales longer than a year seem to be related to pulses of brackish water arriving from the north, via the
East Greenland Current, for example, "The Great Salinity Anomaly," described by Dickson et al.
