Note
A zone of topographic prominences along Florida's eastern continental
shelf edge has been mapped, using side- scan sonar and fathometer
tracings. This zone (27°49. 5N and 79 ͦ58. 5'W), designated
"Sebastian Pinnacle System", is extremely complex and contains a concentration
of major shelf edge features resulting from combined geophysical
and biological forces. Substrate distribution patterns indicate
strong depositional and erosional activity by the Florida Current.
