another group the mean curve for which is shown in figure 37. This 

 has a shape similar to that found for the mixed water in the Grand 

 Banks region in 1952, but 0.1 to 0.2 poorer in phosphorus. It was 

 also poorer in phosphorus than the central Labrador Sea in 1952 and 

 similar to that found in 1953. In the stations southwest of Cape 

 Farewell, only 5712 and 5713 departed from this central Labrador 

 Sea group and they were richer in phosphorus. Except for the 25- and 

 50-meter values at station 5712, these two stations fell into the group 

 from the Greenland triangle representative of the East Greenland
