The Adriatic Abyssal Plain , more commonly referred to as the Adriatic Basin , is an oceanic basin under the Adriatic Sea . The Adriatic Sea 's average depth is 252.5 metres ( 828 ft ) , and its maximum depth is 1,233 metres ( 4,045 ft ) ; however , the North Adriatic basin rarely exceeds a depth of 100 metres ( 330 ft ) .
The Mediterranean Sea is a sea connected to the Atlantic Ocean , surrounded by the Mediterranean Basin and almost completely enclosed by land : on the north by Southern Europe and Anatolia , on the south by North Africa and on the east by the Levant . Although the sea is sometimes considered a part of the Atlantic Ocean , it is usually referred to as a separate body of water . Geological evidence indicates that around 5.9 million years ago , the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years ( the Messinian salinity crisis ) before being refilled by the Zanclean flood about 5.3 million years ago . It covers an area of about 2,500,000 km2 ( 970,000 sq mi ) , representing 0.7% of the global ocean surface , but its connection to the Atlantic via the Strait of Gibraltar - the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates Spain in Europe from Morocco in Africa - is only 14 km ( 9 mi ) wide . In oceanography , it is sometimes called the Eurafrican Mediterranean Sea or the European Mediterranean Sea to distinguish it from mediterranean seas elsewhere . The Mediterranean Sea has an average depth of 1,500 m ( 4,900 ft ) and the deepest recorded point is 5,267 m ( 17,280 ft ) in the Calypso Deep in the Ionian Sea . It lies between latitudes 30° and 46° N and longitudes 6° W and 36° E. Its west-east length , from the Strait of Gibraltar to the Gulf of Iskenderun , on the southeastern coast of Turkey , is about 4,000 kilometres ( 2,500 mi ) . The sea was an important route for merchants and travellers of ancient times , facilitating trade and cultural exchange between peoples of the region . The history of the Mediterranean region is crucial to understanding the origins and development of many modern societies . The countries surrounding the Mediterranean in clockwise order are Spain , France , Monaco , Italy , Slovenia , Croatia , Bosnia and Herzegovina , Montenegro , Albania , Greece , Turkey , Syria , Lebanon , Israel , Egypt , Libya , Tunisia , Algeria , and Morocco ; Malta and Cyprus are island countries in the sea . In addition , the Gaza Strip and the British Overseas Territories of Gibraltar and Akrotiri and Dhekelia have coastlines on the sea .
The Agulhas Bank ( /əˈɡʌləs/ , from Portuguese for Cape Agulhas , Cabo das Agulhas , Cape of Needles ) is a broad , shallow part of the southern African continental shelf which extends up to 250 km ( 160 mi ) south of Cape Agulhas before falling steeply to the abyssal plain . It is the ocean region where the warm Indian Ocean and the cold Atlantic Ocean meet . This convergence leads to treacherous sailing conditions , accounting for numerous wrecked ships in the area over the years . However the meeting of the oceans here also fuels the nutrient cycle for marine life , making it one of the best fishing grounds in South Africa .
The Atlantic Ocean is the second largest of the world 's oceans , with an area of about 106,460,000 square kilometers ( 41,100,000 square miles ) . It covers approximately 20 percent of Earth 's surface and about 29 percent of its water surface area . It separates the Old World from the New World . The Atlantic Ocean occupies an elongated , S-shaped basin extending longitudinally between Europe and Africa to the east , and the Americas to the west . As one component of the interconnected World Ocean , it is connected in the north to the Arctic Ocean , to the Pacific Ocean in the southwest , the Indian Ocean in the southeast , and the Southern Ocean in the south ( other definitions describe the Atlantic as extending southward to Antarctica ) . The Equatorial Counter Current subdivides it into the North ( ern ) Atlantic Ocean and the South ( ern ) Atlantic Ocean at about 8°N . Scientific explorations of the Atlantic include the Challenger expedition , the German Meteor expedition , Columbia University 's Lamont-Doherty Earth Observatory and the United States Navy Hydrographic Office .
The Alaska Plain , also referred to as the Alaskan Plain or Alaskan Abyssal Plain , is an oceanic basin under the Gulf of Alaska . The plain is bordered to the northwest by the Alaskan portion of the Aleutian Trench , to the north and east by the continental shelf off the coast of Alaska and British Columbia , and to the south by two separate lines of seamounts , from Patton seamount in the northwest , located just south of Kodiak Island , to Bowie seamount in the southeast , located just west of Queen Charlotte Islands , running from 54°40′N 150°30′W / 54.667°N 150.500°W / 54.667 ; -150.500 and 53°18′N 135°38′W / 53.300°N 135.633°W / 53.300 ; -135.633 .
The Pacific Ocean is the largest and deepest of Earth 's oceanic divisions . It extends from the Arctic Ocean in the north to the Southern Ocean ( or , depending on definition , to Antarctica ) in the south and is bounded by the continents of Asia and Australia in the west and the Americas in the east . At 165,250,000 square kilometers ( 63,800,000 square miles ) in area ( as defined with an Antarctic southern border ) , this largest division of the World Ocean - and , in turn , the hydrosphere - covers about 46% of Earth 's water surface and about one-third of its total surface area , making it larger than all of Earth 's land area combined . The centers of both the Water Hemisphere and the Western Hemisphere are in the Pacific Ocean . The equator subdivides it into the North ( ern ) Pacific Ocean and South ( ern ) Pacific Ocean , with two exceptions : the Galápagos and Gilbert Islands , while straddling the equator , are deemed wholly within the South Pacific . Its mean depth is 4,000 meters ( 13,000 feet ) . Challenger Deep in the Mariana Trench , located in the western north Pacific , is the deepest point in the world , reaching a depth of 10,928 meters ( 35,853 feet ) . The Pacific also contains the deepest point in the Southern Hemisphere , the Horizon Deep in the Tonga Trench , at 10,823 meters ( 35,509 feet ) . The third deepest point on Earth , the Sirena Deep , is also located in the Mariana Trench . The western Pacific has many major marginal seas , including the South China Sea , the East China Sea , the Sea of Japan , the Sea of Okhotsk , the Philippine Sea , the Coral Sea , and the Tasman Sea .
The geology of the Iberian Peninsula consists of the study of the rock formations on the Iberian Peninsula , which includes Spain , Portugal , Andorra , and Gibraltar . The peninsula contains rocks from every geological period from the Ediacaran to the Quaternary , and many types of rock are represented . World-class mineral deposits are also found there . The core of the Iberian Peninsula consists of a Hercynian cratonic block known as the Iberian Massif . On the northeast this is bounded by The Pyrenean fold belt , and on the southeast it is bounded by the Betic Fold mountain chain . These two fold chains are part of the Alpine belt . To the west , the peninsula is delimited by the continental boundary formed by the opening of the Atlantic Ocean . The Hercynian Fold belt is mostly buried by Mesozoic and Cenozoic cover rocks to the east , but nevertheless outcrops through the Iberian Chain and the Catalan Coastal Ranges .
The Alboran Sea ( from Arabic البحران , al-Baḥrān ) is the westernmost portion of the Mediterranean Sea , lying between the Iberian Peninsula and the north of Africa ( Spain on the north and Morocco and Algeria on the south ) . The Strait of Gibraltar , which lies at the west end of the Alboran Sea , connects the Mediterranean with the Atlantic Ocean .
The Aleutian Basin is an oceanic basin under the southwestern Bering Sea . While the northeastern half of the Bering Sea overlies the North American Plate in relatively shallow water , the Aleutian Basin consists of oceanic plate - the remnant of the Kula Plate that was mostly subducted under the North American Plate . Subduction of the Kula Plate ceased after the creation of the Aleutian Trench to its south . What remained of the Kula Plate attached to the North American Plate . This former subduction zone is now the Beringian Margin , which now hosts sixteen submarine canyons , including Zhemchug Canyon , the world 's largest . The deep-water part of the Bering Sea is separated into the Commander and Bowers basins by the submarine Shirshov Ridge and Bowers Ridge . The Commander Basin occupies the western part of the Bering Sea , with the Shirshov Ridge on its eastern border . The Shirshov Ridge extends 750 km southward from the Russian Olyutorskii Peninsula to connect with Bowers Ridge . The Bowers Ridge extends in the form of an arc over approximately 900 km from the Aleutian Islands Arc to the northwestern termination , where it meets Shirshov Ridge . This former island arc , Bowers Ridge , is a prominent semi-circular-shaped geological that meets the Aleutian arc and , together with the Aleutians , bounds Bowers Basin .
The Amerasia Basin , or Amerasian Basin , is one of the two major basins from which the Arctic Ocean can be subdivided ( the other one being the Eurasian Basin ) . The triangular-shaped Amerasia Basin broadly extends from the Canadian Arctic Islands to the East Siberian Sea , and from Alaska to the Lomonosov Ridge . The basin can be further subdivided based on bathymetric features ; these include the Canada Basin , the Makarov Basin , the Podvodnikov Basin , the Alpha-Mendeleev Ridge , and the Chukchi Plateau . The Amerasia Basin is connected to the Pacific Ocean via the Bering Strait and to the North Atlantic Ocean via the Eurasia Basin and the Fram Strait . The continental shelf around the Amerasia Basin is very broad , averaging up to 342 mi ( 550 km ) in width . The average depth of the Amerasia Basin is 12,960 ft ( 3,950 m ) , and it covers 2,500,000 km2 ( 970,000 sq mi ) . The Canada Basin ( with a maximum depth of 4,000 m ( 13,000 ft ) ) is underlain by oceanic crust at its centre , as well as extended continental crust and transitional-type crust around its margins . The Makarov and Podvodnikov basins , may include oceanic crust , though have also been suggested to be highly extended continental crust or intruded by volcanics . The Alpha and Mendeleev ridges ( also collectively referred to as the Alpha-Mendeleev Ridge ) are considered to be predominantly volcanic in origin , possibly with a component of extended continental crust underneath . The Chukchi Plateau is made of continental crust . Many scenarios have been proposed for the opening of the Amerasia Basin . The most popular , the windshield wiper model , proposes that the Arctic Alaska-Chukotka terrane ( AAC ) was rotated in a counter-clockwise motion , away from the Canadian Arctic Islands during the Late Jurassic-Cretaceous in one or several stages .
The Amundsen Basin , with depths up to 4.4 km , is the deepest abyssal plain in the Arctic Ocean . The Amundsen Basin is embraced by the Lomonosov Ridge ( from 81°N 140°E / 81°N 140°E / 81 ; 140 ( Lomonosov Ridge , Siberian Side ) to 80°N 40°W / 80°N 40°W / 80 ; -40 ( Lomonosov Ridge , Greenland Side ) ) and the Gakkel Ridge ( from 81°N 120°E / 81°N 120°E / 81 ; 120 ( Arctic Mid Ocean Ridge , Siberian Side ) to 85°N 10°E / 85°N 10°E / 85 ; 10 ( Arctic Mid Ocean Ridge , Greenland Side ) ) . It is named after the polar researcher Roald Amundsen . Together with the Nansen Basin , the Amundsen Basin is often summarized as Eurasian Basin . The Russian-American cooperation Nansen and Amundsen Basin Observational System ( NABOS ) aims to provide a quantitative observationally based assessment of circulation , water mass transformations , and transformation mechanisms in the Eurasian and Canadian Basins of the Arctic Ocean .
The Arctic Ocean is the smallest and shallowest of the world 's five major oceans . It is also known as the coldest of all the oceans . The International Hydrographic Organization ( IHO ) recognizes it as an ocean , although some oceanographers call it the Arctic Sea . It is sometimes classified as an estuary of the Atlantic Ocean , and it is also seen as the northernmost part of the all-encompassing World Ocean . Located mostly in the Arctic north polar region in the middle of the Northern Hemisphere , besides its surrounding waters the Arctic Ocean is surrounded by Eurasia and North America . It is partly covered by sea ice throughout the year and almost completely in winter . The Arctic Ocean 's surface temperature and salinity vary seasonally as the ice cover melts and freezes ; its salinity is the lowest on average of the five major oceans , due to low evaporation , heavy fresh water inflow from rivers and streams , and limited connection and outflow to surrounding oceanic waters with higher salinities . The summer shrinking of the ice has been quoted at 50% . The US National Snow and Ice Data Center ( NSIDC ) uses satellite data to provide a daily record of Arctic sea ice cover and the rate of melting compared to an average period and specific past years .
Amundsen Plain ( 65°0′S 125°0′W / 65.000°S 125.000°W / -65.000 ; -125.000Coordinates : 65°0′S 125°0′W / 65.000°S 125.000°W / -65.000 ; -125.000 ) is an undersea abyssal plain named in association with Amundsen Coast . The name was approved by the Advisory Committee on Undersea Features in June 1988 .
The Southern Ocean , also known as the Antarctic Ocean or the Austral Ocean , [ note 4 ] comprises the southernmost waters of the World Ocean , generally taken to be south of 60° S latitude and encircling Antarctica . As such , it is regarded as the second-smallest of the five principal oceanic divisions : smaller than the Pacific , Atlantic , and Indian Oceans but larger than the Arctic Ocean . This oceanic zone is where cold , northward flowing waters from the Antarctic mix with warmer subantarctic waters . By way of his voyages in the 1770s , James Cook proved that waters encompassed the southern latitudes of the globe . Since then , geographers have disagreed on the Southern Ocean 's northern boundary or even existence , considering the waters as various parts of the Pacific , Atlantic , and Indian Oceans , instead . However , according to Commodore John Leech of the International Hydrographic Organization ( IHO ) , recent oceanographic research has discovered the importance of Southern Circulation , and the term Southern Ocean has been used to define the body of water which lies south of the northern limit of that circulation . This remains the current official policy of the IHO , since a 2000 revision of its definitions including the Southern Ocean as the waters south of the 60th parallel has not yet been adopted . Others regard the seasonally-fluctuating Antarctic Convergence as the natural boundary . The maximum depth of the Southern Ocean , using the definition that it lies south of 60th parallel , was surveyed by the Five Deeps Expedition in early February 2019 . The expedition 's multibeam sonar team identified the deepest point at 60° 28 ' 46S , 025° 32 ' 32W , with a depth of 7,434 meters . The expedition leader and chief submersible pilot Victor Vescovo , has proposed naming this deepest point in the Southern Ocean the Factorian Deep , based on the name of the manned submersible DSV Limiting Factor , in which he successfully visited the bottom for the first time on February 3 , 2019 .
The Angola Basin is located along the West African South Atlantic Margin which extends from Cameroon to Angola . It is characterized as a passive margin that began spreading in the south and then continued upwards throughout the basin . This basin formed during the initial breakup of the supercontinent Pangaea during the early Cretaceous , creating the Atlantic Ocean and causing the formation of the Angola , Cape , and Argentine basins . It is often separated into two units : the Lower Congo Basin , which lies in the northern region and the Kwanza Basin which is in the southern part of the Angola margin . The Angola Basin is famous for its Aptian Salt Basins , a thick layer of evaporites that has influenced topography of the basin since its deposition and acts as an important petroleum reservoir .
The Argentine Abyssal Plain forms part of the Argentine Basin off the east coast of Argentina . It comprises the deepest sections of the basin on the western and south-western margins , reaching a depth of 6,212m ( 20,381 feet ) .
The Atlantic-Indian Basin is a large undersea basin . The name was approved by the Advisory Committee for Undersea Features ( ACUF ) in July 1963 after a review of a National Geographic Society globe .
The Balearic Sea ( endotoponym : Mar Balear in Catalan and Spanish ) is a body of water in the Mediterranean Sea near the Balearic Islands . It is not to be confused with the Alboran Sea or the Iberian shelf waters . The Ebro River flows into this small sea .
The Baffin Basin is an oceanic basin located in the middle of Baffin Bay between Baffin Island and Greenland . With a maximum depth of over 2,700 m ( 8,900 ft ) , the basin represents the deepest point of Baffin Bay . The basin formed as a result of seafloor spreading at the time of the opening of Baffin Bay around 56 million years ago .
Bellingshausen Plain ( 64°0′S 90°0′W / 64.000°S 90.000°W / -64.000 ; -90.000Coordinates : 64°0′S 90°0′W / 64.000°S 90.000°W / -64.000 ; -90.000 ) , also known as Bellinghausen Abyssal Plain , is an undersea plain parallel to the continental rise in the Bellingshausen Sea , named for Admiral Fabian Gottlieb von Bellingshausen , commander of the Russian Antarctic Expedition ( 1818-1821 ) . The name was approved by the Advisory Committee for Undersea Features in April , 1974 .
The Blake Basin , also called the Blake-Bahama Basin , is a deep area of the Atlantic Ocean which runs along the east coast of the United States . It starts at the northern part of the Bahamas and continues up toward New York . Depth exceeds 5400 meters between the Blake Plateau and Blake Escarpment to the South and West , and the Blake Bahama Outer Ridge .
