the 1,500-decibar surface, the net vohime transport was 1.46 north- 

 westerly. Although available observations are few, our conception of 

 the circulation balance is that there is a small net contribution through 

 the northern openings into the Baffin Bay-Labrador Sea system and 

 a small sinking and outflow into the North Atlantic below the reference 

 surface. These have been estimated to be of the order of a million 

 cubic meters per second. If the reference surface of 1,500 decibars is 

 acceptable, the sinking and outflow below it must have exceeded the
