Animation of the thermohaline circulation. The later part of this animation shows the Antarctic Circumpolar Current. 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.
Nearly all of Antarctica is covered by a sheet of ice that is, on average, at least 1,500 m (5,000 ft) thick. Antarctica contains 90% of the world's ice and more than 70% of its fresh water. If all the land-ice covering Antarctica were to melt—around 30 × 10 ^ 6 km 3 (7.2 × 10 ^ 6 cu mi) of ice—the seas would rise by over 60 m (200 ft). [22]
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 ...
Mawson is the only Antarctic station to use wind generators designed to take advantage of the fierce katabatic winds. Two 300 kW wind turbines were installed in 2003, but one failed in 2017. Two 300 kW wind turbines were installed in 2003, but one failed in 2017.
The latest data shows high temperatures in portions of East Antarctica – where the most abnormal conditions are ongoing – that are typically between minus 58 and minus 76 degrees Fahrenheit ...
In July–September, Jason Box prepared for and occupied a camp near the Arctic Circle for 7 weeks during which time he conducted surface energy budget (melt) and supra-glacial melt lake measurements. 2008 During a 3-week field campaign, Jason Box, Ian Howat, Slawek Tulaczyk, and Yushin Ahn conducted measurements on Store Glacier, west ...
