The key role of the Southern Annular Mode during the sea-ice maximum for Antarctic sea ice and its recent loss [PDF]
Communications Earth & EnvironmentAntarctic sea ice exhibits considerable interannual variability and has experienced unprecedented decline over the past decade. Here we provide observational insights into the role of the Southern Annular Mode in driving such variations in Antarctic sea ...

Import of Atlantic Water and sea ice controls the ocean environment in the northern Barents Sea [PDF]
Ocean Science, 2022 The northern Barents Sea is a cold, seasonally ice-covered Arctic shelf sea region that has experienced major warming and sea ice loss in recent decades.

Anomalous collapses of Nares Strait ice arches leads to enhanced export of Arctic sea ice
Nature Communications, 2021 The ice arches that usually develop at the northern and southern ends of Nares Strait play an important role in modulating the export of Arctic Ocean multi-year sea ice.

Record low Antarctic sea ice coverage indicates a new sea ice state
Communications Earth & Environment, 2023 In February 2023, Antarctic sea ice set a record minimum; there have now been three record-breaking low sea ice summers in seven years. Following the summer minimum, circumpolar Antarctic sea ice coverage remained exceptionally low during the autumn and ...

Classification of sea ice types in Sentinel-1 synthetic aperture radar images [PDF]
The Cryosphere, 2020 A new Sentinel-1 image-based sea ice classification algorithm using a machine-learning-based model trained in a semi-automated manner is proposed to support daily ice charting.

Robust but weak winter atmospheric circulation response to future Arctic sea ice loss
Nature Communications, 2022 The possibility that Arctic sea ice loss weakens mid-latitude westerlies, promoting more severe cold winters, has sparked more than a decade of scientific debate, with apparent support from observations but inconclusive modelling evidence.

The Copernicus Global 1/12° Oceanic and Sea Ice GLORYS12 Reanalysis
Frontiers in Earth Science, 2021 GLORYS12 is a global eddy-resolving physical ocean and sea ice reanalysis at 1/12° horizontal resolution covering the 1993-present altimetry period, designed and implemented in the framework of the Copernicus Marine Environment Monitoring Service (CMEMS).

Record Low Antarctic Sea Ice Cover in February 2022
Geophysical Research Letters, 2022 On 25 February 2022 Antarctic sea ice extent dropped to a satellite‐era record low level of 1.92 × 106 km2, 0.92 × 106 km2 below the long‐term mean. The area of sea ice was also at a record low level of 1.24 × 106 km2.

Sea Ice Properties in High‐Resolution Sea Ice Models [PDF]
Journal of Geophysical Research: Oceans, 2021 AbstractAn Arctic sea ice‐ocean model is run with three uniform horizontal resolutions (6, 4, and 2 km) and identical sea ice and ocean model parameterizations, including an isotropic viscous‐plastic sea ice rheology, a mechanical ice strength parameterization, and an ice ridging parameterization. Driven by the same atmospheric forcing, the three model
