This is sometimes referred to as a unit of standard atmospheres (atm). Total atmospheric mass is 5.1480×10 18 kg (1.135×10 19 lb), [ 42 ] about 2.5% less than would be inferred from the average sea level pressure and Earth's area of 51007.2 megahectares, this portion being displaced by Earth's mountainous terrain.
When looking at carbon flux from the atmosphere to the ocean, this region is considered one of the highest in the world's oceans. This region is also known as being one of the few bodies of water that take up large quantities of carbon dioxide yearly, ranging from 20 to 85 g C m −2 y −1 , [ 2 ] which is considered high in comparison the ...
The Atlantic Ocean is the second-largest of the world's five oceanic divisions, with an area of about 85,133,000 km 2 (32,870,000 sq mi). [2] It covers approximately 17% of Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South ...
Antarctic Circumpolar Current (ACC) is an ocean current that flows clockwise (as seen from the South Pole) from west to east around Antarctica. An alternative name for the ACC is the West Wind Drift. The ACC is the dominant circulation feature of the Southern Ocean and has a mean transport estimated at 100–150 Sverdrups (Sv, million m 3 /s ...
The Arctic Ocean is the smallest and shallowest of the world's five oceanic divisions. [ 1 ] It spans an area of approximately 14,060,000 km 2 (5,430,000 sq mi) and is the coldest of the world's oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea ...
It runs along the sea-floor from the Bouvet Triple Junction in the South Atlantic Ocean south-westward to a major transform fault boundary east of the South Sandwich Islands. Near the Bouvet Triple Junction the spreading half rate is 9 mm/a (0.35 in/year), which is slow, and the SAAR has the rough topography characteristic of slow-spreading ridges.
The ocean is a major driver of Earth's water cycle. Ocean water represents the largest body of water within the global water cycle (oceans contain 97% of Earth's water). Evaporation from the ocean moves water into the atmosphere to later rain back down onto land and the ocean. [ 68 ]
Gravimetric data from Cassini's December 2010 flybys showed that Enceladus likely has a liquid water ocean beneath its frozen surface, but at the time it was thought the subsurface ocean was limited to the south pole. [26] [27] [28] [97] The top of the ocean probably lies beneath a 30 to 40 kilometers (19 to 25 mi) thick ice shelf. The ocean ...
