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

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).

Sea Ice Extent Retrieval Using CSCAT 12.5 km Sampling Data

Remote Sensing
Polar sea ice extent exhibits a highly dynamic nature. This paper investigates the sea ice extent retrieval on a fine (6.25 km) grid based on the 12.5 km sampling data from the China France Ocean Satellite Scatterometer (CSCAT), which is generated by an ...

The spatiotemporal patterns of sea ice in the Bohai Sea during the winter seasons of 2000–2016

International Journal of Digital Earth, 2019
In this study, sea ice thickness (SIT) and sea ice extent (SIE) in the Bohai Sea from 2000 to 2016 were investigated. A surface heat balance equation was applied to calculate SIT using ice surface temperatures estimated from the Moderate Resolution ...

Interannual and seasonal variability of Arctic sea ice extent according to satellite observations

Российская Арктика, 2019
The interannual and seasonal changes of Arctic sea ice extent according to satellite observations from 1978–2018 are analyzed. Steady reduction in the sea ice cover over the research period is reported.

An assessment of the Arctic Ocean in a suite of interannual CORE-II simulations. Part I: Sea ice and solid freshwater [PDF]

, 2016
The Arctic Ocean simulated in fourteen global ocean-sea ice models in the framework of the Coordinated Ocean-ice Reference Experiments, phase II (CORE II) is analyzed. The focus is on the Arctic sea ice extent, the solid freshwater (FW) sources and solid

Arctic sea ice minimum extent

Eos, Transactions American Geophysical Union, 2012
The extent of Arctic sea ice dropped to 3.41 million square kilometers on 16 September, 760,000 square kilometers below the minimum ice extent in 2007, which had been the low mark since the satellite record began in 1979, the National Snow and Ice Data Center (NSIDC) announced.

Bellingshausen Sea ice extent recorded in an Antarctic Peninsula ice core [PDF]

Journal of Geophysical Research: Atmospheres, 2016
AbstractAnnual net accumulation (An) from the Bruce Plateau (BP) ice core retrieved from the Antarctic Peninsula exhibits a notable relationship with sea ice extent (SIE) in the Bellingshausen Sea. Over the satellite era, both BP An and Bellingshausen SIE are influenced by large‐scale climatic factors such as the Amundsen Sea Low, Southern Annular Mode,

Changes of the Arctic marginal ice zone during the satellite era [PDF]

The Cryosphere, 2020
Many studies have shown a decrease in Arctic sea ice extent. It does not logically follow, however, that the extent of the marginal ice zone (MIZ), here defined as the area of the ocean with ice concentrations from 15 % to 80 %, is also ...
