The entire ocean, containing 97% of Earth's water, spans 70.8% of Earth's surface, [8] making it Earth's global ocean or world ocean. [ 23 ] [ 25 ] This makes Earth, along with its vibrant hydrosphere a "water world" [ 43 ] [ 44 ] or " ocean world ", [ 45 ] [ 46 ] particularly in Earth's early history when the ocean is thought to have possibly ...

Sea has several definitions: [a] A division of an ocean, delineated by landforms, [6] currents (e.g., Sargasso Sea), or specific latitude or longitude boundaries. This includes but is not ...
The term can now also be taken to refer to these seven oceanic bodies of water: [2] [3] [4] the Arctic Ocean; the North Atlantic Ocean; the South Atlantic Ocean; the Indian Ocean; the North Pacific Ocean; the South Pacific Ocean; the Southern (or Antarctic) Ocean; The World Ocean is also known as just "the sea", the expanse emanating from any ...
The Indian Ocean covers 70,560,000 km 2 (27,240,000 sq mi), including the Red Sea and the Persian Gulf but excluding the Southern Ocean, or 19.5% of the world's oceans. Its volume is 264,000,000 km 3 (63,000,000 cu mi) or 19.8% of the world's oceans' volume; it has an average depth of 3,741 m (12,274 ft) and a maximum depth of 7,290 m (23,920 ft).
On average, the Atlantic is the saltiest major ocean; surface water salinity in the open ocean ranges from 33 to 37 parts per thousand (3.3–3.7%) by mass and varies with latitude and season. Evaporation, precipitation, river inflow and sea ice melting influence surface salinity values.
A gyre is a circular ocean current formed by the Earth's wind patterns and the forces created by the rotation of the planet. [33] There are five main ocean gyres: the North and South Pacific Subtropical Gyres, the North and South Atlantic Subtropical Gyres, and the Indian Ocean Subtropical Gyre. There are significant garbage patches in each of ...
The Southern Ocean, also known as the Antarctic Ocean, [1] [note 4] comprises the southernmost waters of the world ocean, generally taken to be south of 60° S latitude and encircling Antarctica. [5] With a size of 21,960,000 km 2 (8,480,000 sq mi), it is the second-smallest of the five principal oceanic divisions, smaller than the Pacific ...
