The General Bathymetric Chart of the Oceans (GEBCO) is a publicly available bathymetric chart of the world's oceans. The project was conceived with the aim of preparing a global series of charts showing the general shape of the seafloor. Over the years it has become a reference map of the bathymetry of the world's oceans for scientists and others.
The series also includes several Check Lists of British Insects. All books contain line drawings, with the most recent volumes including colour photographs. In recent years, new volumes in the series have been published by Field Studies Council, and benefit from association with the AIDGAP identification guides and Synopses of the British Fauna.
A large spawning site for the species is located at Glover's Reef, off the Belizean coast. It has been identified as one of only two viable sites remaining for the species, of 9 originally known locations. In 2002, a permanent marine protected area was established on Glover's Reef. However, the Nassau grouper's spawning region is not included ...
A coastal lagoon is, as the definition above, simply a body of water that is separated from the ocean by a barrier. An atoll lagoon is a circular coral reef or several coral islands that surround a lagoon. Atoll lagoons are often much deeper than coastal lagoons. [24]
Canton Island typifies the isolated coral atolls dotting the Pacific Ocean. The Structure and Distribution of Coral Reefs, Being the first part of the geology of the voyage of the Beagle, under the command of Capt. Fitzroy, R.N. during the years 1832 to 1836, was published in 1842 as Charles Darwin's first monograph, and set out his theory of the formation of coral reefs and atolls.
The reef manta ray can grow to a disc size of up to 5 m (16 ft) but average size commonly observed is 3 to 3.5 m (11 ft). [7] [10] It is dorsoventrally flattened and has large, triangular pectoral fins on either side of the disc. At the front, it has a pair of cephalic fins which are forward extensions of the pectoral fins. These can be rolled ...
Elkhorn coral (Acropora palmata) is an important reef-building coral in the Caribbean. The species has a complex structure with many branches which resemble that of elk antlers; hence, the common name. The branching structure creates habitat and shelter for many other reef species.
Coral reefs are usually found in specific zones. These zones depict different habitats. The known zones are the fore reef, reef crest, and backreef. All zones are connected and have important roles in the growth and development of the reefs. Coral reefs that are found surrounding islands were created when islands recede into the ocean. [5]
