A coast – also called the coastline, shoreline, or seashore – is the land next to the sea or the line that forms the boundary between the land and the ocean or a lake. Coasts are influenced by the topography of the surrounding landscape, as well as by water induced erosion, such as waves. The geological composition of rock and soil dictates the type of shore that is created. Earth contains roughly 620,000 km (390,000 mi) of coastline.
Maldives is an island country in the Indian Ocean, South Asia, south-southwest of India. It has a total land size of 298 km2 (115 sq mi) which makes it the smallest country in Asia. It consists of approximately 1,190 coral islands grouped in a double chain of 26 atolls, spread over roughly 90,000 square kilometers, making this one of the most geographically dispersed countries in the world. It has the 31st largest exclusive economic zone of 923,322 km2 (356,497 sq mi). Composed of live coral reefs and sand bars, the atolls are situated atop a submarine ridge, 960 km (600 mi) long that rises abruptly from the depths of the Indian Ocean and runs from north to south. Only near the southern end of this natural coral barricade do two open passages permit safe ship navigation from one side of the Indian Ocean to the other through the territorial waters of Maldives. For administrative purposes the Maldives government organized these atolls into twenty-one administrative divisions.
Andros Island is an archipelago within The Bahamas, the largest of the Bahamian Islands. Politically considered a single island, Andros in total has an area greater than all the other 700 Bahamian islands combined. The land area of Andros consists of hundreds of small islets and cays connected by mangrove estuaries and tidal swamplands, together with three major islands: North Andros, Mangrove Cay, and South Andros. The three main islands are separated by bights, estuaries that trifurcate the island from east to west. It is 167 kilometres (104 mi) long by 64 km (40 mi) wide at the widest point.
A cay, also spelled caye or key, is a small, low-elevation, sandy island on the surface of a coral reef. Cays occur in tropical environments throughout the Pacific, Atlantic, and Indian oceans, including in the Caribbean and on the Great Barrier Reef and Belize Barrier Reef.
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.
Eleuthera refers both to a single island in the archipelagic state of the Commonwealth of the Bahamas and to its associated group of smaller islands. Eleuthera forms a part of the Great Bahama Bank. The island of Eleuthera incorporates the smaller Harbour Island. "Eleuthera" derives from the feminine form of the Greek adjective ἐλεύθερος (eleútheros), meaning "free". Known in the 17th century as Cigateo, it lies 80 km east of Nassau. It is long and thin—180 km long and in places little more than 1.6 km wide. At its narrowest point, the Glass Window Bridge, which has been called the narrowest place on earth, Eleuthera stands 30 feet wide. Its eastern side faces the Atlantic Ocean and its western side faces the Great Bahama Bank. The topography of the island varies from wide rolling pink sand beaches to large outcrops of ancient coral reefs and the highest elevation point is 200 feet. The population is approximately 11,000 and the principal economy of the island is tourism.
Exuma is a district of The Bahamas, consisting of over 365 islands and cays.
Egg Island is an uninhabited island, officially an islet, comprising 800 m2 (8,611 sq ft) in the Bahamas. It is thought to be named because of the supposed chickens owned by residents of other nearby islands who travel here to collect the eggs; however, there are no chickens on Egg Island. Another theory is that local sea bird eggs were often collected here by the first settlers, these were then wiped out by the introduction of goats to the island a long time ago.
Harbour Island is an island and administrative district in the Bahamas located off the northeast coast of Eleuthera Island. Harbour Island, Jacobs Island, Man Island (Bahamas), Pierre Island and others form what looks like a reef that encloses the east and north sides of a lagoon in the northeast corner of Eleuthera.
Spanish Wells is a district of the Bahamas. The settlement consists of a medium-sized town on the island of St. George's Cay 610 m (2,000 ft) wide by 2,860 m (9,380 ft) long, located approximately 500 m (1,600 ft) off the northern tip of Eleuthera island. According to the 2022 census, it has a population of 1,608 residents.
CocoCay or Little Stirrup Cay, sometimes titled Perfect Day at CoCoCay is one of the Berry Islands, a collection of Bahamian cays and small islands located approximately 55 miles (89 km) north of Nassau. It is used for tourism by Royal Caribbean Group exclusively. Little Stirrup Cay is adjacent to Great Stirrup Cay, Norwegian Cruises' private island since 1977.
Eustatia Island is a 30-acre island of the British Virgin Islands (BVI) in the Caribbean. The word "Eustatia" is a Greek derived word meaning, "good place to stay." The entire island, and a small neighboring island, Saba Rock, are under the same long term lease. The island is regularly featured and photographed for several publications and was listed as one of the top 20 most beautiful islands in the world in the December 2004 issue of Islands magazine.
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.
Oolitic aragonite sand is composed of the calcium carbonate mineral, aragonite, with an egg-like shape and sand grain size. This sand type forms in tropical waters through precipitation, sedimentation, and microbial activity, and is indicative of high energy environments. The production of oolitic aragonite sand in the Bahamas surpasses anyplace else in the world. Changes in seawater chemistry and paleoenvironments can be interpreted by the sand's chemical composition and structure.
The Laguna Madre is a long, shallow, hypersaline lagoon along the western coast of the Gulf of Mexico in Nueces, Kenedy, Kleberg, Willacy and Cameron Counties in Texas, United States. It is one of seven major estuaries along the Gulf Coast of Texas. The roughly 20-mile (32 km) long Saltillo Flats land bridge divides it into Upper and Lower lagoons joined by the Intracoastal Waterway, which has been dredged through the lagoon. Cumulatively, Laguna Madre is approximately 130 miles (210 km) long, the length of Padre Island in the US. The main extensions include Baffin Bay in Upper Laguna Madre, Red Fish Bay just below the Saltillo Flats, and South Bay near the Mexican border. As a natural ecological unit, the Laguna Madre of the United States is the northern half of the ecosystem as a whole, which extends into Tamaulipas, Mexico approximately 144 miles (232 km) south of the US border, to the vicinity of the Rio Soto La Marina and the town of La Pesca, extending approximately 275 miles (443 km) through USA and Mexico in total.
The Sea of Abaco, located in The Bahamas, is an approximately 100 kilometres long saltwater lagoon separating Great Abaco Island from a chain of barrier islands known as the Abaco Cays. Depths in the Sea of Abaco are generally a few metres, and shallow reefs and shoals can pose a serious hazard to navigation. Despite these hazards, the sea is popular with boaters and is sometimes referred to as a 'marine highway', offering a sheltered passage through the Abaco Islands. The majority of the largest settlements and towns in the Abaco Islands are located along the shores of the sea.
MV Logna was built as general cargo ship in Bergens Mekaniske Verksted, Shipyard, Norway in 1958. She transported cargo between Norway and Spain until 1969, when she was acquired by the Bahama Cement Company. In 1970, she was converted to a bulk cement carrier and she was renamed MV Island Cement. She was used to ship bulk cement between Freeport, Bahamas, Fort Pierce, Port Canaveral, and Fort Lauderdale, Florida, and to Eleuthera and New Providence in the Bahamas. In 1980, the Company conducted an underwater survey and determined that it was not economical to perform required repairs. Instead, the ship was decommissioned and the company planned to sell her for scrap.
Staniel Cay is an island located in The Exuma Cays, a district of The Bahamas.
The poleward migration of coral species refers to the phenomenon brought on by rising sea temperatures, wherein corals are colonising cooler climates in an attempt to circumvent coral bleaching, rising sea levels and ocean acidification. In the age of Anthropocene, the changing global climate has disrupted fundamental natural processes and brought about observable changes in the submarine sphere. Whilst coral reefs are bleaching in tropical areas like the Great Barrier Reef, even more striking, and perhaps more alarming; is the growth of tropical coral species in temperate regions, which has taken place over the past decade. Coral reefs are frequently compared to the "canaries in the coal mine," who were used by miners as an indicator of air quality. In much the same way, "coral reefs are sensitive to environmental changes that could damage other habitats in the future," meaning they will be the first to visually exhibit the true implications of global warming on the natural world.
