Upwelling in Atlantic shelf waters of South Florida.

Subsurface temperature data from 8 stations were obtained for 6 wk during thesummer of 1978 to describe seasonal upwelling along the Atlantic coast of Florida just south ofCape Canaveral. Available data show one major upwelling event occurring during the first 3 wkof August. Bottom temperatures suggest that cool water advances rapidly toward the coast, andnearshore water cools by as much as 7°C within 2 wk. A strong thermocline is maintainedthroughout the upwelling event. The available data base is inadequate to resolve the primaryforcing mechanisms, but related studies suggest that upwelling may occur in response to theFlorida Current as much as to the coastal wind field.
