Sea Ice Extent Retrieval Using CSCAT 12.5 km Sampling Data
Remote SensingPolar 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 ...

A twenty-first century structural change in Antarctica’s sea ice system
Communications Earth & EnvironmentFrom 1979 to 2016, total Antarctic sea ice extent experienced a positive trend with record winter maxima in 2012 and 2014. Record summer minima followed within the period 2017-2024, raising the possibility that the Antarctic sea ice system might be ...

Modulation of the Seasonal Cycle of Antarctic Sea Ice Extent Related to the Southern Annular Mode
Geophysical Research Letters, 2017 Through analysis of remotely sensed sea surface temperature (SST) and sea ice concentration data, we investigate the impact of winds related to the Southern Annular Mode (SAM) on sea ice extent around Antarctica.

The potential of sea ice leads as a predictor for seasonal Arctic sea ice extent prediction [PDF]
, 2018 . The Arctic sea ice extent throughout the melt season is closely associated with initial sea ice state in winter and spring. Sea ice leads are important sites of energy fluxes in the Arctic Ocean, which may play an important role in the evolution of ...

Sea salt as an ice core proxy for past sea ice extent: A process‐based model study [PDF]
Journal of Geophysical Research D: Atmospheres, 2014 AbstractSea ice is a reflection of, and a feedback on, the Earth's climate. We explore here, using a global atmospheric chemistry‐transport model, the use of sea salt in Antarctic ice cores to obtain continuous long‐term, regionally integrated records of past sea ice extent, synchronous with ice core records of climate.
