A Comparison Of Benthic Habitats And Faunas Between The Miami Terrace (Proposed Calypso Pipeline Site) And The Pourtales Terrace (Coral Habitat Of Particular Concern), Laura Dell
HCNSO Student Theses and Dissertations
Quantitative photographs of benthic communities at two northern Miami Terrace sites, originally investigated as part of an environmental impact survey in advance of the proposed Calypso pipeline, and two Pourtalès Terrace sites, investigated as part of an exploration of deep-sea coral and sponge ecosystems (DSCEs) within the Pourtalès Terrace Deep-water Coral Habitat Area of Particular Concern (CHAPC), were reanalyzed and compared for similarities and differences. Both terraces are part of an elongated lithified platform that parallels the southeastern Florida coast at depths averaging between 250 and 450 m. Although both sites have similar geological origins and lie under the Florida …
Benthic Invertebrate Communities And Habitat Characterization Of The Pourtalès Terrace, Florida With Analysis Of The Deepwater Coral Habitat Areas Of Particular Concern And The East Hump Marine Protected Area, Jana K. Ash
HCNSO Student Theses and Dissertations
The Pourtalès Terrace is a gently curved, narrow triangular platform that parallels the Florida Keys for 213 km running from southern Key Largo to between Key West and the Marquesas Keys. The main Terrace surface begins in 200 m and dips gently to approximately 450 m, where the Pourtalès Escarpment slopes steeply to the deep floor of the southern Straits of Florida. The Terrace platform exhibits a wide variety of Neogene-age geological features, including high-relief ledges, mounds, sinkholes and deep-water biogenic build-ups called bioherms. Previous research revealed dense and diverse benthic assemblages dominated by stylasterid hydrocorals, octocorals and sponges.
