Northern Smith Sound Oceanography - Summer 1977.
An oceanograpic research program was conducted in northern Smith Sound during the middle July 1977 using USCGC WESTWIND (W-AGB 281) as the data collection platform. One aspect of the program was to investigate the water mass interactions at the narrowest portion of Smith Sound which: (1) represents...

An oceanograpic research program was conducted in northern Smith Sound during the middle July 1977 using USCGC WESTWIND (W-AGB 281) as the data collection platform.
