The Bahamas, officially the Commonwealth of The Bahamas, is an island country within the Lucayan Archipelago of the Atlantic Ocean. It contains 97% of the Lucayan Archipelago's land area and 88% of its population. The archipelagic country consists of more than 3,000 islands, cays, and islets in the Atlantic Ocean, and is located north of Cuba and northwest of the island of Hispaniola and the Turks and Caicos Islands, southeast of the U.S. state of Florida and east of the Florida Keys. The capital is Nassau on the island of New Providence. The Royal Bahamas Defence Force describes the Bahamas' territory as encompassing 470,000 km2 (180,000 sq mi) of ocean space.
Limestone is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life.
The Lucayan people were the original residents of The Bahamas and the Turks and Caicos Islands before the European colonisation of the Americas. They were a branch of the Taínos who inhabited most of the Caribbean islands at the time. The Lucayans were the first Indigenous Americans encountered by Christopher Columbus. Shortly after contact, the Spanish kidnapped and enslaved Lucayans with the displacement culminating in the complete eradication of the Lucayan people from the Bahamas by 1520.
Oolite or oölite is a sedimentary rock formed from ooids, spherical grains composed of concentric layers. Strictly, oolites consist of ooids of diameter 0.25–2 millimetres; rocks composed of ooids larger than 2 mm are called pisolites. The term oolith can refer to oolite or individual ooids.
Inagua is the southernmost district of the Bahamas, comprising the islands of Great Inagua and Little Inagua. The headquarters for the district council are in Matthew Town.
The Lucayan Archipelago, also known as the Bahamian Archipelago, is an island group comprising the Commonwealth of The Bahamas and the British Overseas Territory of the Turks and Caicos Islands. The archipelago is in the western North Atlantic Ocean, north of Cuba and the other Antillean Islands, and east and south-east of Florida.
Silver Bank is a submerged bank in the Atlantic Ocean north of the Dominican Republic and southeast of the territory of Turks and Caicos Islands. It covers an area of 1,680 square kilometres. It is separated from Mouchoir Bank in the west by Silver Bank Passage, and from Navidad Bank in the east by Navidad Bank Passage.
Navidad Bank is a submerged bank in the Atlantic Ocean north of the Dominican Republic and southeast of the Territory of Turks & Caicos. It is separated from Silver Bank by the wide Navidad Bank Passage.
The Tongue of the Ocean (TOTO) is the name of a region of much deeper water in the Bahamas separating the islands of Andros and New Providence.
South Caicos is the seventh-largest island in the Turks and Caicos archipelago, with a land area of 21.2 square kilometres. South Caicos is known for excellent fishing, both deep-sea and bone fishing, and scuba diving. South Caicos was formerly a salt exporter, the island still hosts a network of salt pans as a reminder of the industry. Today, the island's main income is derived from small-scale commercial fishing.
A blue hole is a large marine cavern or sinkhole, which is open to the surface and has developed in a bank or island composed of a carbonate bedrock. Blue holes typically contain tidally influenced water of fresh, marine, or mixed chemistry. They extend below sea level for most of their depth and may provide access to submerged cave passages. Well-known examples are the Dragon Hole and, in the Caribbean, the Great Blue Hole and Dean's Blue Hole.
A carbonate platform is a sedimentary body which possesses topographic relief, and is composed of autochthonic calcareous deposits. Platform growth is mediated by sessile organisms whose skeletons build up the reef or by organisms which induce carbonate precipitation through their metabolism. Therefore, carbonate platforms can not grow up everywhere: they are not present in places where limiting factors to the life of reef-building organisms exist. Such limiting factors are, among others: light, water temperature, transparency and pH-Value. For example, carbonate sedimentation along the Atlantic South American coasts takes place everywhere but at the mouth of the Amazon River, because of the intense turbidity of the water there. Spectacular examples of present-day carbonate platforms are the Bahama Banks under which the platform is roughly 8 km thick, the Yucatan Peninsula which is up to 2 km thick, the Florida platform, the platform on which the Great Barrier Reef is growing, and the Maldive atolls. All these carbonate platforms and their associated reefs are confined to tropical latitudes. Today's reefs are built mainly by scleractinian corals, but in the distant past other organisms, like archaeocyatha or extinct cnidaria were important reef builders.
Mouchoir Bank, in Spanish also called Banco de Pañuelo Blanco, is a submerged bank that is part of the Turks and Caicos Islands and falls within its exclusive economic zone.
The West Indies is a subregion of North America, surrounded by the North Atlantic Ocean and the Caribbean Sea, which comprises 13 independent island countries and 19 dependencies in three archipelagos: the Greater Antilles, the Lesser Antilles, and the Lucayan Archipelago.
An ocean bank, sometimes referred to as a fishing bank or simply bank, is a part of the seabed that is shallow compared to its surrounding area, such as a shoal or the top of an underwater hill. Somewhat like continental slopes, ocean bank slopes can upwell as tidal and other flows intercept them, sometimes resulting in nutrient-rich currents. Because of this, some large banks, such as Dogger Bank and the Grand Banks of Newfoundland, are among the richest fishing grounds in the world.

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 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.
The Bahamas are a country within the Lucayan Archipelago of the West Indies in the Caribbean.
