The Pacific Ocean is the largest of the Earth's oceanic divisions.It extends from the Arctic in the north to the Southern Ocean in the south,bounded by Asia and Australia in the west,and the Americas in the east.
At 165.25 million square kilometres (63.8 million square miles) in area,this largest division of the World Ocean 鈥 and,in turn,the hydrosphere 鈥 covers about 46% of the Earth's water surface and about one-third of its total surface.[1] The equator subdivides it into the North Pacific Ocean and South Pacific Ocean,with two exceptions:the Gal谩pagos and Gilbert Islands,while straddling the equator,are deemed wholly within the South Pacific.[2] The Mariana Trench in the western North Pacific is the deepest point in the Pacific and in the world,reaching a depth of 10,911 metres (35,797 ft).[3]
The Pacific Ocean was sighted by Europeans early in the 16th century,first by the Spanish explorer Vasco N煤ñez de Balboa who crossed the Isthmus of Panama in 1513 and named it Mar del Sur (South Sea).Its current name was given by Portuguese explorer Ferdinand Magellan during the Spanish expedition of world circumnavigation in 1521,who encountered calm seas during the journey and called it Tepre Pacificum in Latin,meaning "pacific" or "peaceful sea".[4]
The Atlantic Ocean is the second-largest of the world's oceanic divisions.With a total area of about 106,400,000 square kilometres (41,100,000 sq mi),it covers approximately twenty percent of the Earth's surface and about twenty-six percent of its water surface area.The first part of its name refers to Atlas of Greek mythology,making the Atlantic the "Sea of Atlas".
The oldest known mention of "Atlantic" is in The Histories of Herodotus around 450 BC (Hdt.1.202.4):Atlantis thalassa (Greek:Ἀ蟿位伪谓蟿ὶς 胃ά位伪蟽蟽伪; English:Sea of Atlas); see also:Atlas Mountains.The term Ethiopic Ocean,derived from Ethiopia,was applied to the southern Atlantic ocean as late as the mid-19th century.[1][2] Before Europeans discovered other oceans,the term "ocean" itself was synonymous with the waters beyond the Strait of Gibraltar that we now know as the Atlantic.The Greeks believed this ocean to be a gigantic river encircling the world.
The Atlantic Ocean occupies an elongated,S-shaped basin extending longitudinally between the Americas to the west,and Eurasia and Africa to the east.As one component of the interconnected global ocean,it is connected in the north to the Arctic Ocean (which is sometimes considered a sea of the Atlantic),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 equator subdivides it into the North Atlantic Ocean and South Atlantic Ocean.
The Indian Ocean is the third largest of the world's oceanic divisions,covering approximately 20% of the water on the Earth's surface.[1] It is bounded on the north by the Indian subcontinent; on the west by East Africa; on the east by Indochina,the Sunda Islands,and Australia; and on the south by the Southern Ocean (or,depending on definition,by Antarctica).The ocean is named after India.[2][3][4][5]
As one component of the interconnected global ocean,the Indian Ocean is delineated from the Atlantic Ocean by the 20掳 east meridian running south from Cape Agulhas,and from the Pacific by the meridian of 146掳55' east.[6] The northernmost extent of the Indian Ocean is approximately 30掳 north in the Persian Gulf.The Indian Ocean has asymmetric ocean circulation[citation needed].This ocean is nearly 10,000 kilometres (6,200 mi) wide at the southern tips of Africa and Australia; its area is 73,556,000 square kilometres (28,350,000 sq mi),[7] including the Red Sea and the Persian Gulf.
The ocean's volume is estimated to be 292,131,000 cubic kilometres (70,086,000 mi3).[8] Small islands dot the continental rims.Island nations within the ocean are Madagascar,the world's fourth largest island; Reunion Island; Comoros; Seychelles; Maldives; Mauritius; and Sri Lanka.The archipelago of Indonesia borders the ocean on the east.
The Arctic Ocean,located in the Northern Hemisphere and mostly in the Arctic north polar region,is the smallest,and shallowest of the world's five major oceanic divisions.[1] The International Hydrographic Organization (IHO) recognizes it as an ocean,although some oceanographers call it the Arctic Mediterranean Sea or simply the Arctic Sea,classifying it as one of the mediterranean seas of the Atlantic Ocean.[2] Alternatively,the Arctic Ocean can be seen as the northernmost part of the all-encompassing World Ocean.
Almost completely surrounded by Eurasia and North America,the Arctic Ocean is partly covered by sea ice throughout the year[3] (and almost completely in winter).The Arctic Ocean's temperature and salinity vary seasonally as the ice cover melts and freezes;[4] its salinity is the lowest on average of the five major oceans,due to low evaporation,heavy freshwater 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%.[1] 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.
