Figure 25. — Departures of temperature and salinity of the Labrador Current 

 in 1958 from the 11-year means 1948-58. Dashed vertical lines indicate 

 the approximate effect on density. 



mediate depths, and is considered to be the combined result of 

 cabbeling and isentropic movement along the offshore margins of 

 the Labrador Current. It would appear from the results sum- 

 marized in figure 25 that these processes of formation of the 

 warm intermediate water were also stimulated by the onshore 

 winds. 



Past bulletins have given the position of the cold wall for each 

 survey of the area southeastward of the Grand Banks in terms 

 of the area between the cold wall and the following rhumb lines : 

 the 45th parallel from the cold wall to 45° N. 49 °W.; the 49th 

 meridian from 45° N. to 43° N. ; a line from 43 °N. 49 W. through 

 42 °N. 47 °W. extended to the cold wall. Using the same criterion 

 as in the past for the location of the cold wall (the horizontal 

 projection of the line along which a temperature of 6 corresponds 

 to a salinity of 34.95°/ ), the area between the cold wall and
