Atlantic Ocean

Atlantic Europe encompasses the western portion of Europe which borders the Atlantic Ocean. The term may refer to the idea of Atlantic Europe as a cultural unit and/or as a biogeographical region.

It comprises Ireland, Great Britain, Iceland, Belgium, the Netherlands, the central and northern regions of Portugal, northwestern and northern Spain (including Galicia, Asturias, Cantabria, Southern Basque Country, and some portions of Castile and León), the southwestern and western portion of France (Northern Basque Country), western Scandinavia as well as western and northern Germany.

Santiago de Compostela, simply Santiago, or Compostela, in the province of A Coruña, is the capital of the autonomous community of Galicia, in northwestern Spain. The city has its origin in the shrine of Saint James the Great, now the Cathedral of Santiago de Compostela, as the destination of the Way of St. James, a leading Catholic pilgrimage route since the 9th century. In 1985, the city's Old Town was designated a UNESCO World Heritage Site.

Santiago de Compostela has a very mild climate for its latitude with heavy winter rainfall courtesy of its relative proximity to the prevailing winds from Atlantic low-pressure systems.

Galicia (/ɡəˈlɪʃ(i)ə/ gə-LISH-(ee-)ə; Galician: Galicia [ɡaˈliθjɐ] (officially) or Galiza [ɡaˈliθɐ] ; Spanish: Galicia [ɡaˈliθja]) is an autonomous community of Spain and historic nationality under Spanish law. Located in the northwest Iberian Peninsula, it includes the provinces of A Coruña, Lugo, Ourense, and Pontevedra.

Galicia is located in Atlantic Europe. It is bordered by Portugal to the south, the Spanish autonomous communities of Castile and León and Asturias to the east, the Atlantic Ocean to the west, and the Cantabrian Sea to the north. It had a population of 2,705,833 in 2024 and a total area of 29,574 km (11,419 sq mi). Galicia has over 1,660 km (1,030 mi) of coastline, including its offshore islands and islets, among them Cíes Islands, Ons, Sálvora, Cortegada Island, which together form the Atlantic Islands of Galicia National Park, and the largest and most populated, A Illa de Arousa.

The walrus (Odobenus rosmarus) is a large pinniped marine mammal with discontinuous distribution about the North Pole in the Arctic Ocean and subarctic seas of the Northern Hemisphere. It is the only extant species in the family Odobenidae and genus Odobenus. This species is subdivided into two subspecies: the Atlantic walrus (O. r. rosmarus), which lives in the Atlantic Ocean, and the Pacific walrus (O. r. divergens), which lives in the Pacific Ocean.

Adult walrus are characterised by prominent tusks and whiskers, and considerable bulk: adult males in the Pacific can weigh more than 2,000 kilograms (4,400 pounds) and, among pinnipeds, are exceeded in size only by the two species of elephant seals. Walrus live mostly in shallow waters above the continental shelves, spending significant amounts of their lives on the sea ice looking for benthic bivalve molluscs. Walruses are relatively long-lived, social animals, and are considered to be a "keystone species" in the Arctic marine regions.

The North Channel (known in Irish and Scottish Gaelic as Sruth na Maoile, in Scots as the Sheuch) is the strait between north-eastern Ireland and south-western Scotland. The Firth of Clyde merges with the channel, between the southern tip of the Kintyre peninsula and Corsewall Point on the Rhins of Galloway. Part of the Irish Sea, the channel begins north of the Isle of Man and runs north-west into the Atlantic Ocean. Within the channel is Beaufort's Dyke, the deepest part of which is 312 metres (1,024 ft).

The Indo-Pacific is a vast biogeographic region of Earth. In a narrow sense, sometimes known as the Indo-West Pacific or Indo-Pacific Asia, it comprises the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the seas connecting the two. The term is especially useful in marine biology, ichthyology, and similar fields, since many marine habitats are continuously connected from Madagascar to Japan and Oceania, and a number of species occur over that range, but are not found in the Atlantic Ocean.

As a distinct marine realm, the region has an exceptionally high species richness, with the world's highest species richness being found in at its heart in the Coral Triangle, and a remarkable gradient of decreasing species richness radiating outward in all directions. The region includes over 3,000 species of fish, compared with around 1,200 in the next richest marine region, the Western Atlantic, and around 500 species of reef building corals, compared with about 50 species in the Western Atlantic.

Nantes (/nɒ̃t/, US also /nɑːnt(s)/; French: [nɑ̃t] ; Gallo: Naunnt or Nantt [nɑ̃(ː)t]; Breton: Naoned [ˈnãunət]) is a city in the Loire-Atlantique department of France on the Loire, 50 km (31 mi) from the Atlantic coast. The city is the sixth largest in France, with a population of 320,732 in Nantes proper and a metropolitan area of nearly 1 million inhabitants (2020). With Saint-Nazaire, a seaport on the Loire estuary, Nantes forms one of the main north-western French metropolitan agglomerations.

It is the administrative seat of the Loire-Atlantique department and the Pays de la Loire region, one of 18 regions of France. Nantes belongs historically and culturally to Brittany, a former duchy and province, and its omission from the modern administrative region of Brittany is controversial.

In geography, the antipode (/ˈæntɪˌpoʊd, ænˈtɪpədi/) of any spot on Earth is the point on Earth's surface diametrically opposite to it. A pair of points antipodal (/ænˈtɪpədəl/) to each other are situated such that a straight line connecting the two would pass through Earth's center. Antipodal points are as far away from each other as possible. The North and South Poles are antipodes of each other.

In the Northern Hemisphere, "the Antipodes" may refer to Australia and New Zealand, and Antipodeans to their inhabitants. Geographically, the antipodes of the British Isles are in the Pacific Ocean, south of New Zealand. This gave rise to the name of the Antipodes Islands of New Zealand, which are close to the antipode of London. The antipodes of Australia are in the North Atlantic Ocean, while parts of Spain, Portugal, France and Morocco are antipodal to New Zealand.

The Tethys Ocean (/ˈtiːθɪs, ˈtɛ-/ TEETH-iss, TETH-; Greek: Τηθύς Tēthús), also called the Tethys Sea or the Neo-Tethys, was a prehistoric ocean during much of the Mesozoic Era and early-mid Cenozoic Era. It was the predecessor to the modern Indian Ocean, the Mediterranean Sea, and the Eurasian inland marine basins (primarily represented today by the Black Sea and Caspian Sea).

During the early Mesozoic, as Pangaea broke up, the designation “Tethys Ocean” refers to the ocean located between the ancient continents of Gondwana and Laurasia. After the opening of the Indian and Atlantic oceans during the Cretaceous Period and the breakup of these continents over the same period, it refers to the ocean bordered by the continents of Africa, Eurasia, India, and Australasia. During the early-mid Cenozoic, the Indian, African, Australian and Arabian plates moved north and collided with the Eurasian plate, which created new borders to the ocean, a land barrier to the flow of currents between the Indian and Mediterranean basins, and the orogenies of the Alpide belt (including the Alps, Himalayas, Zagros, and Caucasus Mountains). All of these geological events, in addition to a drop in sea level from Antarctic glaciation, brought an end to the Tethys as it previously existed, fragmenting it into the Indian Ocean, the Mediterranean Sea, and the Paratethys.

The Bahamas, officially the Commonwealth of the Bahamas, is an island country located within the Lucayan Archipelago in the Atlantic Ocean. It contains 97 per cent of the archipelago's land area and 88 per cent of its population. It comprises more than 3,000 islands, cays and islets in the Atlantic Ocean, located north of Cuba and north-west of the island of Hispaniola (split between the Dominican Republic and Haiti) and the Turks and Caicos Islands, southeast of the US state of Florida and east of the Florida Keys. The capital and largest city is Nassau on the island of New Providence. The Royal Bahamas Defence Force describes the Bahamas' territory as encompassing 470,000 km (180,000 sq mi) of ocean space.

The Bahama islands were inhabited by the Arawak and Lucayans, a branch of the Arawakan-speaking Taíno, for many centuries. Christopher Columbus was the first European to see the islands, making his first landfall in the "New World" in 1492 when he landed on the island of San Salvador. Later, the Kingdom of Spain shipped the native Lucayans to Hispaniola and enslaved them there, after which the Bahama islands were mostly deserted from 1513 until 1648, as nearly all native Bahamians had been forcibly removed for enslavement or had died of European diseases. In 1649 English colonists from Bermuda, known as the Eleutheran Adventurers, settled on the island of Eleuthera.
