Oceanographic Data from Northwest Greenland Sea: Arctic East 1979 Survey of the USCGC Westwind.
Abstract
The near-surface horizontal temperature and salinity distributions suggest a westward surface flow across the continental shel south of Belgica Bank (over Belgica Dyb between 77 deg N and 78 deg N) and an eastward surface flow north of Belgica Bank between 80 deg N and 81 deg N. These distributions are thus consistent with an anticyclonic surface flow around Belgica Bank. Warm (> 0 C) deep water appears to move shoreward along Belgica Dyb and perhaps north of Belgica Bank and is found in the deep along-shore troughs. Polar Water temperature minimum characteristics, while uniform within local geographic areas, showed significant large scale variations. Particular differences could be found between the continental shelf area and the East Greenland Current north and south of Nord. Sections across the East Greenland Current indicate that often two of these minima can be identified and that they are coherent over several stations. Gross sound speed structure appears uniform over fairly large geographic regions. Even small scale anomalies, such as associated with temperature inversions, were often coherent over several 100's of km. (Author)
