Abstract 



From the data collected on the Labrador Current Expedition, July- 

 August 1965, there is indicated substantiation of the current system 

 defined by Smith (1937), "Marion Expedition." The data further 

 shows that Hudson Strait exercises a control on the Labrador Current 

 to the extent that a characteristic water tyjie is formed and pulsed 

 eastward by tidal variations through tlie strait entrance, fonning the 

 cold core and main flow of the Labrador Current. Contributions from 

 the Baffin Land Current, flowing westward into Hudson Strait along 

 the northern shore, appear to form one of the mixing constituents; 

 with Hudson Bay acting as a modifier tending to warm and dilute the 

 waters prior to their outflow along the southern shore of Hudson 

 Strait.
