;3. ABSTRACT 



Oceanographic data were collected during a cruise of USS EDISTO (AGB 2) to the 

 northern Greenland Sea and adjacent Arctic Ocean during the summer of 1964. The 

 resulting data indicate that many of the prevailing ideas concerning the oceanography 

 of the region are correct, but some modifications and additions are suggested. 



The center of the East Greenland Current appeared to be farther east than is 

 indicated on some earlier charts, and the meanders and gyres also differed from those 

 shown in some earlier current schemes. 



Minimum bottom water temperatures in the survey region appear to be warmer than 

 they were at the beginning of the century, and some current ideas on the formation 

 and movement of Arctic Bottom Water do not seem to be well substantiated. 



High dissolved oxygen saturations were found at great depths and can be explained 

 by the proximity of areas of bottom water formation, by the oxidation of a large 

 portion of organic material before the deeper waters left the surface, and by the 

 absence of a significant amount of sinking organic material. 



Micronutrient concentrations were low indicating that water from the North 

 Atlantic was the primary component of the waters in the survey region. Photosynthetic 

 processes appeared to be lowering near-surface micronutrient concentrations and, 

 in some instances, raising oxygen concentrations. In cases where production may 

 have been limited by micronutrient deficiencies, nitrate appears to have been the 

 limiting nutrient. No pronounced oxygen minimum or micronutrient maxima were 

 encountered within a definite depth range in the survey area. Micronutrient relation- 

 ships in the different water masses differed and can be explained to some extent 

 by current theories on the formation and movement of these, watprs.
