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), [ 1 ] or possibly even higher, [ 2 ] making it the largest ocean current.
The AMRC is one of the primary archives of meteorological data from Antarctica and its surrounding geographic areas. [1] The Antarctic Meteorological Forecast Center (AMFC) at UW-Madison was devised during the same time as the founding of the AMRC as a provider of weather forecasts for research vessels operating in the vicinity of Antarctica.
Locations of all known installed Antarctic automatic weather stations as of 2009 Current locations of all known installed Antarctic automatic weather stations. Data from the UW-Madison Antarctic AWS program has been used for many research studies including, but not limited to: boundary layer meteorology studies near the South Pole, Katabatic wind studies at Reeves Glacier and the Adelie Coast ...
Nearly 1,500 academics, researchers and scientists specializing in Antarctica gathered in southern Chile for the 11th Scientific Committee on Antarctic Research conference this week to share the ...
A schematic overview of the Southern Ocean overturning circulation. The arrows point in the direction of the water movement. The lower cell of the circulation is depicted by the upwelling arrows south of the Antarctic Circumpolar Current (ACC) and the formation of Antarctic Bottom Water beneath the sea ice of Antarctica due to buoyancy loss.
The polar cell, terrain, and katabatic winds in Antarctica can create very cold conditions at the surface, for instance the lowest temperature recorded on Earth: −89.2 °C at Vostok Station in Antarctica, measured in 1983. [6] [7] [8]
This group has conducted studies of the Dry Valleys region of Antarctica since 1993 as part of the NSF’s Long-Term Ecological Research (LTER) program. [7] [8] Ongoing projects in Antarctica include drilling into the subglacial ecosystem of "Blood Falls" in the Dry Valleys and measuring glacial melt input into the Southern Ocean in West ...
The fastest wind ever recorded was in the base Belgrano II at 351 km/h (218 mph). Antarctica has the world's lowest rainfall average (zero at the Geographic South Pole) and thus is the world's driest continent. Despite its low rainfall average, Antarctica has approximately 70% of the world's fresh water (as well as 90% of the world's ice).
