ASWEPS Shallow Water Investigation - Virginia Capes Area
2007
Fisher, Jr, Alvan
Thermal structure of a rectangular area approximately 140 kilometers on a side contiguous to the Continental Shelf northeast of Cape Hatteras was investigated between 19 September and 13 October 1968. Major features included an area of warm (>21C) surface water inshore of the northern wall of the Gulf Stream and a strong sound channel impinging upon the Continental Slope. A subsurface temperature maximum was observed beneath warm surface water at 70 percent of all deepwater stations. Zero layer depths occurred at 56 percent of relatively cold (<19C) water stations over the Continental Shelf. These features persisted throughout the survey.
