what is the size of the artic ocean
Arctic Ocean The Arctic Ocean occupies a roughly circular basin and covers an area of about 14,056,000 km2 (5,427,000 sq mi), almost the size of Antarctica.[8][9] The coastline is 45,390 km (28,200 mi) long.[8][10] It is surrounded by the land masses of Eurasia, North America, Greenland, and by several islands.
World Ocean The unity and continuity of the World Ocean, with relatively free interchange among its parts, is of fundamental importance to oceanography.[2] It is divided into a number of principal oceanic areas that are delimited by the continents and various oceanographic features: these divisions are the Atlantic Ocean, Arctic Ocean (sometimes considered a sea of the Atlantic), Indian Ocean, Pacific Ocean, and Southern Ocean, defined by the International Hydrographic Organization (IHO) in 2000, based on evidence that this region of the World Ocean has a distinct ecosystem and a unique impact on global climate.[3]. In turn, oceanic waters are interspersed by many smaller seas, gulfs, and bays.
