A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.
Ko Phi Phi Le or Ko Phi Phi Leh is an island of the Phi Phi Archipelago, Andaman Sea. It is in the Krabi province of Thailand and is part of Hat Noppharat Thara–Mu Ko Phi Phi National Park.
A reef is a ridge or shoal of rock, coral, or similar relatively stable material lying beneath the surface of a natural body of water. Many reefs result from natural, abiotic (non-living) processes such as deposition of sand or wave erosion planing down rock outcrops. However, reefs such as the coral reefs of tropical waters are formed by biotic (living) processes, dominated by corals and coralline algae. Artificial reefs, such as shipwrecks and other man-made underwater structures, may occur intentionally or as the result of an accident. These are sometimes designed to increase the physical complexity of featureless sand bottoms to attract a more diverse range of organisms. Reefs are often quite near to the surface, but not all definitions require this.
The Virgin Islands National Park is an American national park preserving about 60% of the land area of Saint John in the United States Virgin Islands, as well as more than 5,500 acres of adjacent ocean, and nearly all of Hassel Island, just off the Charlotte Amalie, Saint Thomas harbor.
An artificial reef (AR) is a human-created freshwater or marine benthic structure. Typically built in areas with a generally featureless bottom to promote marine life, it may be intended to control erosion, protect coastal areas, block ship passage, block the use of trawling nets, support reef restoration, improve aquaculture, or enhance scuba diving and surfing. Early artificial reefs were built by the Persians and the Romans.
The Florida Keys National Marine Sanctuary is a U.S. National Marine Sanctuary in the Florida Keys. It includes the Florida Reef, the only barrier coral reef in North America and the third-largest coral barrier reef in the world. It also has extensive mangrove forest and seagrass fields. The Florida Keys National Marine Sanctuary, designated in 1990, is the ninth national marine sanctuary to be established in a system that comprises 13 sanctuaries and two marine national monuments. The Florida Keys National Marine Sanctuary protects approximately 2,900 square nautical miles of coastal and ocean waters from the estuarine waters of south Florida along the Florida Keys archipelago, encompassing more than 1,700 islands, out to the Dry Tortugas National Park, reaching into the Atlantic Ocean, Florida Bay and the Gulf of Mexico.
Fragmentation in multicellular or colonial organisms is a form of asexual reproduction or cloning, where an organism is split into fragments upon maturation and the spilted part becomes the new individual.
Nusa Dua is a resort area built in the 1970s in the southern part of Bali, Indonesia. Known as an enclave of large five-star resorts, it covers 350 hectares of land and encloses more than 20 resorts. It is located 22 kilometers from Denpasar, the provincial capital of Bali, and is administered as part of Benoa subdistrict (kelurahan) in South Kuta, Badung Regency. Nusa Dua means two islands, because there are two islands in the bay of the Indonesia Tourism Development Corporation (ITDC) area. On the southern side lies Peninsula Island, and on the northern side lies Nusa Dharma Island, which is smaller but shadier, and which contains the Pura/Temple Nusa Dharma.
Reef Ball Foundation, Inc. is a 501(c)(3) non-profit organization that functions as an international environmental non-governmental organization. The foundation uses reef ball artificial reef technology, combined with coral propagation, transplant technology, public education, and community training to build, restore and protect coral reefs. The foundation has established "reef ball reefs" in 59 countries. Over 550,000 reef balls have been deployed in more than 4,000 projects.
Apo Reef is a coral reef system in the Philippines situated in the western waters of Occidental Mindoro province in the Mindoro Strait. Encompassing 34 square kilometres (13 sq mi), it is considered the world's second-largest contiguous coral reef system, and is the largest in the country. The reef and its surrounding waters are protected areas administered as the Apo Reef Natural Park (ARNP). It is one of the best known and most popular diving regions in the country, and is in the tentative list for UNESCO World Heritage Sites.
Lovina Beach is a beach on the northwestern side of the island of Bali, Indonesia.
Isla de Ratones also known as Cayo Ratones or Isla Ratones is a small island located near the Joyuda Lagoon in Cabo Rojo, Puerto Rico. The island is a popular spot for snorkeling and bathing.
Coral reef protection is the process of modifying human activities to avoid damage to healthy coral reefs and to help damaged reefs recover. The key strategies used in reef protection include defining measurable goals and introducing active management and community involvement to reduce stressors that damage reef health. One management technique is to create Marine Protected Areas (MPAs) that directly limit human activities such as fishing.
The Cancún Underwater Museum is a non-profit organization based in Cancún, Mexico devoted to the art of conservation. The museum has a total of 500 sculptures, by a series of international and local sculptors, with three different galleries submerged between three and six meters deep in the ocean at the Cancún National Marine Park. The museum was thought up by Marine Park Director Jaime González Cano, with the objective of saving the nearby coral reefs by providing an alternative destination for divers. It was started in 2009 and officially opened in November 2010.
Coral aquaculture, also known as coral farming or coral gardening, is the cultivation of corals for commercial purposes or coral reef restoration. Aquaculture is showing promise as a tool for restoring coral reefs, which are dying off around the world. The process protects young corals while they are most at risk of dying. Small corals are propagated in nurseries and then replanted on the reef.
Organizations which currently undertake coral reef and atoll restoration projects using simple methods of plant propagation:
Sisters’ Islands Marine Park is a 400,000 square metre(40ha) marine park located in Southern Islands planning area, Singapore, which was designated a marine protected area (MPA) by the Government of Maritime and Port Authority of Singapore in 2014. The park encompasses the land and waters surrounding Sisters' Islands, and also covers the western coasts of both St John's Island and Pulau Tekukor.
An electric reef is an artificial reef made from biorock, being limestone that forms rapidly in seawater on a metal structure from dissolved minerals in the presence of a small electric current. The first reefs of this type were created by Wolf Hilbertz and Thomas J. Goreau in the 1980s. By 2011 there were examples in over 20 countries.
Coral reef restoration strategies use natural and anthropogenic processes to restore damaged coral reefs. Reefs suffer damage from a number of natural and man-made causes, and efforts are being made to rectify the damage and restore the reefs. This involves the fragmentation of mature corals, the placing of the living fragments on lines or frames, the nurturing of the fragments as they recover and grow, and the transplantation of the pieces into their final positions on the reef when they are large enough.
Reef burials are a type of "green" or "natural" burial considered by some to be an eco-friendly alternative to traditional burial. Cremation ash is mixed with concrete to form objects that are placed on the seafloor to encourage wildlife in areas where sea life has been diminished.
