Oceanographic data were collected during a cruise of USS EDISTO (AGB 2) in the Norwegian Sea area during the summer of 1963. General oceanographic features were found to agree with previous descriptions of the area. Slight differences in current patterns as presented by recent investigators, mainly in the branching of the Norwegian Current, also were substantiated by 1963 EDISTO data. Norwegian Sea Deep Water temperatures were warmer than those observed earlier in the century. This warming trend also has been reported by recent investigators. Norwegian Sea Deep Water was found overflowing the Iceland-Faeroe Ridge into the North Atlantic Ocean. This overflow was found to be a mixture of 10 parts Norwegian Sea Deep Water to 1 part Atlantic Water. Nutrient relationships were different in the various water masses. Norwegian Sea Deep Water was noticeably higher in reactive phosphorus and reactive silicate than were the surface waters. (Author).

In August-September 1963, a high degree of stratification for both temperature and salinity was observed in the Laptev and East Siberian Seas. Temperatures decreased with depth and with distance away from the Siberian coast, and salinities decreased vertically from the bottom and toward the coast. The five large rivers emptying into the Laptev Sea influence the temperature-salinity characteristics to a great extent causing high temperatures and low salinities near the coast and in the upper layers seaward. The Lena River fluvial plume, on the basis of salinity distribution, was observed to extend in a north to northeasterly direction from the river delta. The combined effects of the Khatanga and Anabar River runoff extended in a northeasterly direction from the Khatanga River Estuary with vertical distribution of the low salinity water limited to the upper 10 meters. Water of three temperature-salinity relationships was observed in the East Siberian Sea in both 1963 and 1964. Near the coast, between the Indigirka River and Chaunskaya Bay, warm low salinity water was observed. In the sea's shallower western regions, cold water with slightly higher salinities was noted. Both of these water types can be attributed to river runoff with cooling and mixing in transit accounting for the colder water and higher salinities. Water in the eastern East Siberian Sea through Long Strait and into the Chukchi Sea was observed to have water as cold as -1.8C and as warm as 1.4C associated with salinities from 28 to 33%. Lower dissolved oxygen values were present in Lena River effluent than in water in the northern and western Laptev Sea. (Author).
