Note(s): The deep-water Oculina coral reef ecosystem is unique and exists solely off the east coast of central Florida. Oculina varicosa forms azooxanthellate colonies up to 2 m in diameter which coalesce into dense thickets on 20-m tall mounds that are thousands of years old. Recently restored videotapes that were made in the 1970s with the Johnson-Sea-Link submersibles show large breeding aggregations of grouper associated with the coral habitat. Historical photographic surveys provide evidence of the status and health of the reefs prior to heavy fishing and trawling activities of the 1980s and 1990s. Recent quantitative analyses by point count of photographic images reveal drastic loss of live coral cover between 1975 and present. Submersible and ROV surveys conducted from 2001 to 2006 suggest that much of the Oculina habitat has been reduced to rubble by bottom trawling which unfortunately is a trend for deep-water reefs worldwide.
