2023年12月6日 · Sea ice is frozen seawater floating on the surface of the ocean. Sea ice is formed entirely in the ocean, unlike icebergs, which originate from land-based sources.

2025年1月2日 · NSIDC ARCTIC SEA ICE AREA (5-day trailing average): 11,563,964 KM2 as at 16-Jan-2025 Hudson Bay sea ice area increasing strongly but sea ice area about one month later than the 2010's average.

2024年1月2日 · NSIDC ARCTIC SEA ICE AREA (5-day trailing average): 10,660,207 KM2 as at 30-Dec-2024 Sea ice area losses in Hudson Bay and the Barents have put the brake on sea ice area gains in the Peripheral Seas.

2025年2月25日 · A real and late recovery in sea ice extentJAXA ARCTIC SEA ICE EXTENT: 13,505,666 KM2 as at 05-Mar-2025 - Extent gain on this day 86k which is 90 k more than the average loss on this day (of the last 10 years) of 4k,

2024年10月3日 · NSIDC ARCTIC SEA ICE AREA (5-day trailing average): 3,456,056 KM2 as at 02-Oct-2024 Some graphs of sea ice area so far this year, illustrating various stages of sea ice decline. Central Artic Region. From the 1980's to the 2000's, summer melt only makes a shallow dip to sea ice area.

For climatologists and physical oceanographers, it is often said that the Arctic is a canary in the environmental coal mine. In the isolated Arctic Ocean Basin, a variety of oceanographic and other processes have conspired to create a layer of cold, salty water called a halocline, which shields the sea ice from underlying warmer waters that would otherwise melt it.

2024年9月15日 · The presence of sea ice, however, depends on a delicate balance between the atmospheric and oceanic heat fluxes. The inflowing Atlantic water contains enough heat to melt the Arctic sea ice in a few years (Turner, 2010), and a small change in oceanic heat flux can have huge implications for the heat balance at the interface.

2018年3月9日 · This Barents Sea ice will vanish quickly, and put us back in first place for the lowest extent. I believe we could then be in first place for the remainder of the season after that, because the Kara and the Laptev will lose ice quickly as well, and keep us there.

Sea levels have risen and fallen throughout geologic history due to a myriad of natural processes, most notably the forming and melting of glaciers. Since the end of the last glacial peak, sea level has risen worldwide on average, but over the past 150 years, the pace of sea level rise has increased as ice melt has hastened and sea water has ...

2025年3月10日 · A magnified Worldview animation at 6-day increments (apologies for the cloudy day which I kept to maintain pacing). Beside the gradual disintegration of parts of the tongue and adjacent fast sea ice, my main interest here is the triangle (grounded or ungrounded?), which weirdly seems to have move backwards in the last frame.Thwaites Glacier Discussion - Page 21
