(Reuters) -Sea ice that packs the ocean around Antarctica hit record low levels this winter, the U.S. National Snow and Ice Data Center (NSIDC) said on Monday, adding to scientists' fears that the ...
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.
The 2023 sea ice cover was 50 to 80 per cent lower than the winter average recorded between 1991 and 2020 in key regions like the Weddell, Ross, and Bellingshausen seas. ... CBS News. Winning ...
Arctic sea ice expands and contracts throughout the year, reaching a peak extent sometime during March, just as the sun rises above the North Pole. It shrinks back during the summer, on its way to ...
The Arctic sea ice minimum is the day in a given year when Arctic sea ice reaches its smallest extent, occurring at the end of the summer melting season, normally during September. Arctic Sea ice maximum is the day of a year when Arctic sea ice reaches its largest extent near the end of the Arctic cold season, normally during March. [14]
Currently, 28% of Arctic basin sea ice is multi-year ice, [2] thicker than seasonal ice: up to 3–4 m (9.8–13.1 ft) thick over large areas, with ridges up to 20 m (65.6 ft) thick. Besides the regular seasonal cycle there has been an underlying trend of declining sea ice in the Arctic in recent decades as well.
Record-breaking low levels of sea ice around Antarctica in 2023 may have been influenced by climate change, scientists have said. Researchers at the the British Antarctic Survey (BAS) analysed ...
