GNU Webster's 1913
- n. (Phys. Geog.) reefs, often of great extent, made up chiefly of fragments of corals, coral sands, and the solid limestone resulting from their consolidation. They are classed as fringing reefs, when they border the land; barrier reefs, when separated from the shore by a broad belt of water; atolls, when they constitute separate islands, usually inclosing a lagoon. See Atoll.

“Finally palæogeography is wholly dependent on this science, as the fossils indicate where there were continents and oceans, where the animal life of the coast developed, where coral reefs grew, where lakes containing fresh water organisms existed, where the primeval tropical forests flourished, and where the tundras of the cold regions extended.”
“Ministers recognised the value and importance of coral reefs and threats to their survival, noting that 2008 was the International Year of Coral Reefs.”

“More than thirty years ago, before Dana and Darwin had published their beautiful investigations upon the coral reefs, a pupil of mine, the late Armand Gressly, had traced the structure and mode of growth of coral reefs and atolls in the Jura mountains, thus anticipating, by a geological investigation, results afterward obtained by dredging in the ocean.”
“Recognising the importance of preserving marine biodiversity, the ICRI seeks to provide for the sustainable management of coral reefs and related ecosystems.”
“The International Coral Reef Workshop, to be chaired by Australia, will develop recommendations on sustainable management of coral reefs for the 1996 meeting of the Commission on Sustainable Development which will review ocean and marine issues.”
