Definition

  • Measurement of the spatial extent or dimensions of coral reefs. A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed by colonies of coral polyps held together by calcium carbonate. They are most commonly found at shallow depths in tropical waters, but deep water and cold water coral reefs exist on smaller scales in other areas. (en)
