Figure 6„ Temporal Variation Diagrams. 



a. The presence of a 0°C isotherm between 500 and 900 meters 

 below which the enormous volume of waters with the uniform salinities 

 characteristic of Arctic Bottom Water was found; 



b. A sharp decrease in salinity as the coast of Greenland is 

 approached; 



c. The presence of Polar Water at depths between and 150 meters 

 in the western portions of the sections with the coldest Polar Water 

 often found close to the region where the horizontal temperature 

 gradients were the greatest;
