As divers, we have a vested interest in protecting the marine environment. In many cases, divers do not have environmental information about their own local sites. The SDI Marine Ecosystems Awareness speciality will increase the Open Water Diver’s understanding of marine environments, the problems facing these unique ecosystems, and the role that divers can play in protecting our marine resources.  Your SDI Instructor will cover your local diving ecosystems as well as others around the globe.
