A current that flows southward from Baffin Bay, through the Davis Strait, and southwestward along the Labrador and Newfoundland coasts.

Labrador Current

 

a cold current in the Atlantic Ocean along the coast of North America. It flows from Baffin Bay to the Grand Banks, where it meets the warm Gulf Stream and sinks to intermediate depths. The Labrador Current moves at a speed of 1–2 km/hr. The water temperature in the winter is below – 1°C and only in the south does it rise to 5°C; in the summer the temperature is 2°C in the north and 10°C in the south. The salinity is 30.0–32.0 parts per thousand. The current carries sea ice and icebergs.

In 1912 the Caribbean experienced an unusually hot summer and so the Gulf Stream was particularly intense; the Titanic hit the iceberg right at the intersection of the Gulf Stream and the Labrador Current.
The icebergs "find their way into the Labrador Current and begin their journey to the southward" in a stop-and-go manner, the 1938 Bowditch manual explains:
On the other hand, High Arctic glacial melt could increase the volumes of sea ice transported to southern latitudes via the Labrador Current, thereby increasing, at least initially, the occurrence of arctic foxes at isolated, southern seabird colonies.
The expedition will then continue west towards Canada, where oceanographers will measure an ocean tract across the Labrador Current before returning to Kangerlussuaq on October 6.
The Labrador Current can clog the nearby Strait of Belle Isle with polar ice any June, and snow lingers in the high ravines of the Tablelands all summer.
But an extremely high spring tide could refloat them, and the ebb tide would carry them back out into the Labrador Current where the icebergs would resume drifting southward," the Daily Mail quoted lead researcher Dr Donald Olson as saying.
The reduction in mobility due to the vertebral injury could have left the whale in a weakened state, potentially unable to swim against the Labrador Current, which flows southward along the Labrador coastline to Newfoundland.
Brackish surface water leaves Hudson Bay through Hudson Strait and joins the Labrador Current.
Outflow from the mouth of Hudson Strait is restricted to its southern half and is deflected southward onto the continental shelf, where it forms the shoremost branch of the Labrador Current (LeBlond et al.
Nevertheless, because convection is sensitive to the presence of a freshwater surface layer (Lazier, 1973, 1980), let us suppose that some brackish water from Hudson Strait mixes across the Labrador Current.
