2023's Antarctic sea ice extent is the lowest on record

Weather
Antarctic sea ice is a vitally important part of the regional and global climate. In 2023, sea ice extent fell to record lows, reaching unprecedented values for both the summer minimum, winter maximum and intervening freeze‐up period.

Antarctic Sea Ice—A Polar Opposite? [PDF]

Oceanography, 2012
As the world's ice diminishes in the face of climate change—from the dramatic decline in Arctic sea ice, to thinning at the margins of both the Greenland and Antarctic ice sheets, to retreating mountain glaciers the world over—Antarctic sea ice presents ...

Polar Sea Ice Monitoring Using HY-2A Scatterometer Measurements

Remote Sensing, 2016
A sea ice detection algorithm based on Fisher’s linear discriminant analysis is developed to segment sea ice and open water for the Ku-band scatterometer onboard the China’s Hai Yang 2A Satellite (HY-2A/SCAT).

Record low 2022 Antarctic sea ice led to catastrophic breeding failure of emperor penguins

Communications Earth & Environment, 2023
The spring season of 2022 saw record low sea ice extent in Antarctica that persisted throughout the year. At the beginning of December, the Antarctic sea ice extent was tracking with the all-time low set in 2021. The greatest regional negative anomaly of

Seasonal forecast of sea ice extent in the Barents sea

Arctic and Antarctic Research, 2019
Earlier, the authors established a close relationship between the temperature of water coming from the North Atlantic and the sea ice extent (SIE) in the Barents Sea, which accounts for up to 75 % of the inter-annual variability of the monthly SIE from January to June.

Estimating the uncertainty of sea-ice area and sea-ice extent from satellite retrievals

The Cryosphere, 2022
Abstract. The net Arctic sea-ice area (SIA) can be estimated from the sea-ice concentration (SIC) by passive microwave measurements from satellites. To be a truly useful metric, for example of the sensitivity of the Arctic sea-ice cover to global warming, we need, however, reliable estimates of its uncertainty.

Airborne radar evidence for tributary flow switching in Institute Ice Stream, West Antarctica: implications for ice sheet configuration and dynamics [PDF]

, 2015
Despite the importance of ice streaming to the evaluation of West Antarctic Ice Sheet (WAIS) stability we know little about mid- to long-term dynamic changes within the Institute Ice Stream (IIS) catchment.

Ice extent trends in the Barents and Kara Seas during recent climate change

Российская Арктика
Certain areas of the Arctic region, primarily the Barents and Kara Seas, have high resource potential. This is the place where hydrocarbon deposits are explored and developed, and where the main transport corridor of the Northern Sea Route begins.

A drop in Antarctic sea ice extent at the end of the 1970s

Communications Earth & Environment
After a period of relative stability, the Antarctic sea ice extent has abruptly decreased in 2016 and has remained low since then. Both atmospheric and oceanic processes likely contributed to this drop but many questions remain regarding the underlying ...

Inland extent of the Weddell Sea Rift imaged by new aerogeophysical data [PDF]

, 2013
The Weddell Sea Rift was a major focus for Jurassic extension and magmatism during the early stages of Gondwana break-up and underlies the Weddell Sea Embayment, which separates East Antarctica from a collage of crustal blocks in West Antarctica.
