FiGXTRE 28.^Dynamic topography of the soa surface relative to the 1,000-decibar

 are indicated and the station numbers given at turning points. 



at about 50 meters and the salinities were lower than normal at depths 

 less than about 200 meters. The mixed water cmve for 1960 approxi- 

 mates the normal eurve down to about 400 meters. Below this depth, 

 and in the Labrador Current water b('h)\v about 600 meters, the 1960 

 values are coIcUm- and Fresher than normal. It is suggested that since

 Baffiidand ('uricnt coming south across Davis Strait ridge might have 

 the effect of lowering both temperature and salinity in the deeper 

 levels of the Labrador ('urrent in the (irand Banks region. As the 

 mixed water contains a gicater proportion of Labrador CiUTent water 

 than Atlantic Current water and as the horizontal velocity of the 

 mixed water is small, and Ix'cause of the relative volume transports of
