Caribbean
The Caribbean (, ) ( es, El Caribe; french: la Caraïbe; ht, Karayib; nl, De Caraïben) is a region of the Americas that consists of the Caribbean Sea, its islands (some surrounded by the Caribbean Sea and some bordering both the Caribbean Sea and the North Atlantic Ocean) and the surrounding coasts. The region is southeast of the Gulf of Mexico and the North American mainland, east of Central America, and north of South America. Situated largely on the Caribbean Plate, the region has more than 700 islands, islets, reefs and cays (see the list of Caribbean islands). Island arcs delineate the eastern and northern edges of the Caribbean Sea: The Greater Antilles and the Lucayan Archipelago on the north and the Lesser Antilles and the on the south and east (which includes the Leeward Antilles). They form the West Indies with the nearby Lucayan Archipelago ( the Bahamas and Turks and Caicos Islands), which are considered to be part of the Caribbean despite not borde ...

Reef
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 component, abiotic processes—deposition (geology), deposition of sand, wave erosion planing down rock outcrops, etc.—but there are also reefs such as the coral reefs of tropical waters formed by biotic component, biotic processes dominated by corals and coralline algae, and artificial reefs such as shipwrecks and other anthropogenic underwater structures may occur intentionally or as the result of an accident, and sometimes have a designed role in enhancing the physical complexity of featureless sand bottoms, to attract a more diverse assemblage of organisms. Reefs are often quite near to the surface, but not all definitions require this. Earth's largest coral reef system is the Great Barrier Reef in Australia, at a length of over . Biotic There is a variety of biotic reef types, including oyster ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coral Reef
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. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, echinode ...

Florida Keys National Marine Sanctuary
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 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. The mission of the sanctuary is to protect the marine resources of the Florida Keys while facilitating human uses that are consistent with the primary objective of resource protecti ...

Long Key
Long Key is an island in the middle Florida Keys. Long Key was called Cayo Víbora (Rattlesnake Key) by early Spanish explorers, a reference to the shape of the island, which resembles a snake with its jaws open, rather than to its denizens. The city of Layton is located on Long Key. The state park (3.9 km²) was dedicated October 1, 1969. U.S. 1 (or the Overseas Highway) crosses the key at approximately mile markers 65.5--71, between Fiesta Key and Conch Key. It is the home of Long Key State Park, a favorite of campers and nature lovers, the camp sites are on the beach but the proximity of US1 makes it noisy. It is smaller and less developed than the neighboring incorporated village of Islamorada to the northeast and city of Marathon to the southwest. History It was visited by C.W. Pierce in his boat, Bonton (1885). He stopped at the lower end of the key where there was a house with a cistern A cistern (Middle English ', from Latin ', from ', "box", from Gre ...

Unmanned Reef Lights Of The Florida Keys
The unmanned reef lights of the Florida Keys were navigational aids erected near the Florida Keys between 1921 and 1935. They were intended to mark local hazards and did not need to be visible for as far as the reef lights that were erected near the Keys during the 19th century. By the time the lights in this list were erected, older lighthouses were being automated, and these new lights were designed to be automated from the start. The lights resembled the older reef lights in having a wrought iron skeletal pyramidal structure on a screw-pile foundation. They all originally had lanterns on their peaks, so that they looked like smaller versions of the older reef lights, but had no keeper's quarters. The first two unmanned lights in the Florida Keys, the Molasses Reef Light and the Pacific Reef Light, were built as square pyramidal towers to the same plan in 1921. The Hen and Chickens Shoal Light was the smallest of these lights, and the only one built as a triangular pyramidal to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
