Bathymetric map of the Gulf of Mexico, with proposed dive sites for Operation Deep-Scope 2005 indicated by red arrows and yellow numbers. Site #1 is on the southwest Florida Shelf in the Gulf of Mexico, where deep-water Lophilia coral lithoherms are found. #2 is DeSoto Canyon, a deep erosional valley where upwelling of deep nutrient rich water means greater animal abundances. #3 is Viosca Knoll, the shallowest site, where spectacular stands of Lophelia provide abundant habitat for other species.
