Current water. This group was richer in phosphorus and similar to 

 that for the Labrador Current in the density range common to both, 

 and below which the high phosphorus Greenland triangle group in- 

 creased to about 1.45 at 27.60 and then decreased slightly with 

 increasing density. The other observations from the Greenland 

 triangle fell into a low phosphorus group, shown in figure 37, similar in 

 phosphorus-density relationship to the observations from the central 

 Labrador Sea and only slightly higher in phosphorus. 



The phosphorus values at all the locations in the Greenland triangle 

 where the salinity was 35°/oo or greater were examined and it was 

 found that except for station 5719 these fell in the low phosphorus 

 group. Water with salinities as great as this must have come from

 concentration and potential density found in the South Wolf Island-Cape 

 Farewell section and the Greenland triangle in 1954. Broken lines show the 

 characteristic phosphorus-density curves for water masses found in the Grand 

 Banks region in May 1952.
