‘Lower sea ice extent means that ocean waves will pound the coast of the giant ice sheet, further reducing ice shelves around Antarctica’ Antarctic sea ice hits new record low in 2023 Skip to ...
Antarctica’s vast expanse of sea ice regulates Earth’s temperature, as the white surface reflects the Sun’s heat back into the atmosphere. Record low sea-ice levels around Antarctica ...
Record low summer sea ice was measured in February 2022 at 741,000 square miles (1.9 million square kilometers) by the National Snow and Ice Data Center. [ 4 ] Since the ocean off the Antarctic coast usually is much warmer than the air above it, the extent of the sea ice is largely controlled by the winds and currents that push it northwards. [ 5 ]
Antarctic sea ice extent peaked this year on Sept. 10, when it covered 16.96 million square kilometers (6.55 million square miles), the lowest winter maximum since satellite records began in 1979 ...
The lowest air temperature record, the lowest reliably measured temperature on Antarctica was set on 21 July 1983, when a temperature of −89.2 °C (−128.6 °F) was observed at Vostok Station. [ 2 ] [ 5 ] For comparison, this is 10.7 °C (19.3 °F) colder than subliming dry ice (at sea level pressure).
Vostok Research Station is around 1,301 kilometres (808 mi) from the Geographic South Pole, at the middle of the East Antarctic Ice Sheet.. Vostok is located near the southern pole of inaccessibility and the south geomagnetic pole, making it one of the optimal places to observe changes in the Earth's magnetosphere.
‘There is some concern that this may be the beginning of a long-term trend of decline for Antarctic sea ice’ Antarctic sea ice hits ‘record-smashing’ new winter low, data shows Skip to ...
The National Snow and Ice Data Center (NSIDC) is a United States information and referral center in support of polar and cryospheric research.NSIDC archives and distributes digital and analog snow and ice data and also maintains information about snow cover, avalanches, glaciers, ice sheets, freshwater ice, sea ice, ground ice, permafrost, atmospheric ice, paleoglaciology, and ice cores.
