Coral associations on submarine terraces in the Bahamian Region

Benthic communities on coral reefs at locations in Florida, the Bahamas, the Turks and Caicos Islands and Haiti were surveyed in October 1972. This survey supplemented the extensive sampling of the reef terrace off Grand Bahama Island made possible due to having access, over several years, to the saturation diving facility, Hydro Lab. Observations were made along 10m line transects. The length occupied by each sessile organism and the distance between organisms were recorded in sequence. The total length of an individual species within a transect was used to calculate the percent cover of that species. A total of 46 transects were completed.Specimens were also collected and returned to the surface for identification to species level where possible.
 Research was undertaken to investigate and compare the little known benthic communities on submarine terraces within the Bahamian region.
