for those stations taken in or near the Atlantic Current, The num- 

 bers shown at the stations in figure 40 give the depth, in meters, of the 

 10° isotherm. An examination of these depths shows a notable 

 correspondence between the contour lines of tliis thermal surface and 

 the indicated course of the dynamic isobaths. Such a correspondence 

 materially supports the current map as drawn.

As was mentioned in the discussion of figure 39, the boundary be- 

 tween the waters having Atlantic Current and Labrador Current char- 

 acteristics, practically all of the water at intermediate depths in the 

 southeastern part of the area had a negative salinity anomaly during 

 this survey. It was considered probable that this was the result of 

 the presence of large quantities of mixed water from the Labrador 

 Current. This view is in accord with figure 40, the relatively low
