Coral reef A fringing reef forms around an extinct volcanic island as the island and ocean floor subsides. As the subsidence continues, the fringing reef becomes a barrier reef and ultimately an atoll reef. Darwin predicted that underneath each lagoon would be a bedrock base, the remains of the original volcano. Subsequent research supported this hypothesis. Darwin's theory followed from his understanding that coral polyps thrive in the tropics where the water is agitated, but can only live within a limited depth range, starting just below low tide. Where the level of the underlying earth allows, the corals grow around the coast
Caribbean Coral Reef Ecosystems Program Caribbean Coral Reef Ecosystems Program The Caribbean Coral Reef Ecosystems (CCRE) program began with a collaborative field project conceived by six National Museum of Natural History scientists during the early 1970s. The scientists interests included a range of disciplines central to reef ecology, including: invertebrate and vertebrate zoology, botany, carbonate geology, and paleobiology. The primary work site is the Carrie Bow Marine Field Station, a research station at Carrie Bow Cay () on the Meso-American Barrier Reef in Belize. The program is an extended duration study of coral reefs, mangroves, sea grass meadows, and the sandy bottoms. It has been
