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 ...
The borders of the oceans are the limits of Earth's oceanic waters.The definition and number of oceans can vary depending on the adopted criteria. The principal divisions (in descending order of area) of the five oceans are the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern (Antarctic) Ocean, and Arctic Ocean.
Today the term South Seas, or South Sea, most commonly refers to the portion of the Pacific Ocean south of the equator. [1] [2] [3] The term South Sea may also be used synonymously for Oceania, or even more narrowly for Polynesia or the Polynesian Triangle, an area bounded by the Hawaiian Islands, New Zealand and Easter Island.
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), [1] or possibly even higher, [2] making it the largest ocean current.
The great capes became landmarks in ocean voyaging due to the hazards they presented to shipping. [2] ... Victoria is the most southern mainland point of Australia, ...
“The Southern Ocean is very stormy in general (but) in the Drake you’re really squeezing (the water) between the Antarctic and the southern hemisphere,” he adds. “That intensifies the ...
The presence of the Drake Passageway allows the three main ocean basins (Atlantic, Pacific and Southern) to be connected via the Antarctic Circumpolar current (ACC), the strongest oceanic current, with an estimated transport of 100–150 Sv (Sverdrups, million m 3 /s). This flow is the only large-scale exchange occurring between the global ...
Southern Ocean overturning circulation consists of two cells in the Southern Ocean, which are driven by upwelling and downwelling. The upwelling in the upper cell is associated with mid-deep water that is brought to the surface, whereas the upwelling in the lower cell is linked to the fresh and abyssal waters around Antarctica.
