Figure 23. — Dynamic topography of the sea surface relative to the 1000-decibar 

 surface from data collected 9-12 July 1962. Oceanographic station positions 

 are indicated and the station numbers given at turning points. 



In figure 21, drawn from data collected during the third survey, the 

 Labi'ador Current is less well defined than during the first survey. 

 There is considerable meandering onto and off of the eastern edge of 

 the Grand Banks, with progressive losses of Labrador CiUTent water 

 through recurvature eastward. The double reversal of direction of 

 the western margin of the Labrador CiUTent in the vicinity of 45° N., 

 49° W., is abnormal and the tongue of higher dynamic heights extend- 

 ing southward along the 49th meridian indicates the remnants of the 

 low^er salinity w^ater found in this vicinity in the first survey. In the
