SPREX
type: Concept
definition: SPREX (Spring Removal Experiment) took place in April 1985 in order to determine the processes affecting the transport and fate of freshwater input to the continental shelf off Georgia and South Carolina during the time of expected high runoff. It was hypothesized that this water is transported offshore in spring by a semi-permanent cyclonic eddy located at about 32/degree/N, 79/degree/W. The SPREX field program included a large array of moored current meters and other instruments, and three research vessels (R/V Cape Florida, R/V Cape Hatteras, and R/V Blue Fin) that conducted hydrographic mapping and biological and chemical sampling. Ship surveys (Cape Hatteras and Cape Florida) were designed to provide near synoptic coverage of a few specific events during SPREX. The purpose of the surveys was to determine the time variations in fresh water content and tracer concentrations over the shelf, the characteristics of shelf water/Gulf Stream water interaction, and biological responses to the events. The general cruise plan was for the Cape Florida to occupy CTD stations along cross-isobath transects out to the shelf break at three primary locations/endash/Savannah, Charleston, and Myrtle Beach. 4 refs., 1 fig., 1 tab.
