The BCD is a mandatory piece of equipment for SCUBA diving. It is an expandable bladder, most commonly worn as an expandable vest, that can be inflated with air from the tank to increase buoyancy while diving. To decrease buoyancy, the BCD is deflated through special air-dump valves or hoses. It provides positive buoyancy for resting, swimming or lending assistance to others under water. The BCD allows maintenance of neutral buoyancy at any depth simply by adding or releasing air. It is also called a buoyancy compensator (BC).

A coral disease characterised by darkly pigmented areas of tissue on stony corals.-At present, there is no known pathogen. The coral tissue remains intact, although at times lesions and coral tissue death are observed in the centres of the pigmented areas. Tissue loss is minimal, if present. This disease is widespread throughout the Caribbean.-For additional information and illustrations, see: http://www.coral.noaa.gov/coral_disease/dark_spots.shtml.
