VARIATIONS IN THE VERTICAL WATER STRUCTURE AT OWS DELTA (44 DEGREES N, 41 DEGREES W).
Abstract
Between June 1962 and July 1963, about 300 nansen casts were made at Ocean Station Vessel DELTA (44 deg N,41 deg W) during five 3-week cruises. Owing to the current at this location, time sampling is equivalent to space sampling. Statistics of the water mass parameters (surface temperature, salinity, sound velocity, depth of maximum salinity, etc.) are thus determined with respect to seasonal effects. The surface water mass is of Gulf Stream origin and extends to depths of 475 to 800 meters. This water mass overlies Subarctic Water which is formed in Denmark Strait and which advects into the area of the station vessel. Water of Mediterranean origin intrudes at depths between 800 and 1,000 meters but constitutes only 6 to 8 percent of the Subarctic (Intermediate) water. North Atlantic Basin water is found at depths between 1,300 and 2,750 meters. The bottom water mass below 2,750 meters is distinctive to the Newfoundland Basin and is warmer and saltier than the North Atlantic Basin Water. (Author)
