d. The presence of a relatively warm intermediate layer beneath 

 the Polar Water resulting from the westward transport of Atlantic 

 Water and indicating the presence of the Return Atlantic Current; 



e. The presence of Atlantic Water in the eastern portions of 

 the sections at depths between 50 and 500 meters 1 ; 



f. High oxygen saturations throughout the water column; 



g. A tendency for micronutrient concentrations to increase 

 with depth; 



h. An increase in reactive phosphorus concentrations in the 

 upper 50 meters as the coast of Greenland is approached.

When present, Polar Water and Atlantic Water would lie within these depth ranges. They 

 J Id not necessarily occupy the entire depth range.
