Geophysical Research Letters, 2020 AbstractWe examine CMIP6 simulations of Arctic sea‐ice area and volume. We find that CMIP6 models produce a wide spread of mean Arctic sea‐ice area, capturing the observational estimate within the multimodel ensemble spread. The CMIP6 multimodel ensemble mean provides a more realistic estimate of the sensitivity of September Arctic sea‐ice area to a ...

Drivers of Antarctic sea ice advance. [PDF]
Nat Commun, 2023 AbstractAntarctic sea ice is mostly seasonal. While changes in sea ice seasonality have been observed in recent decades, the lack of process understanding remains a key challenge to interpret these changes. To address this knowledge gap, we investigate the processes driving the ice season onset, known as sea ice advance, using remote sensing and in ...

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.

Recent observations of superimposed ice and snow ice on sea ice in the northwestern Weddell Sea [PDF]
The Cryosphere, 2021 Abstract. Recent low summer sea ice extent in the Weddell Sea raises questions about the contributions of dynamic and thermodynamic atmospheric and oceanic energy fluxes. The roles of snow, superimposed ice, and snow ice are particularly intriguing, as they are sensitive indicators for changes in atmospheric forcing, and as they could trigger snow ...

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.

Summertime sea-ice prediction in the Weddell Sea improved by sea-ice thickness initialization [PDF]
Scientific Reports, 2021 AbstractSkillful sea-ice prediction in the Antarctic Ocean remains a big challenge due to paucity of sea-ice observations and insufficient representation of sea-ice processes in climate models. Using a coupled general circulation model, this study demonstrates skillful prediction of the summertime sea-ice concentration (SIC) in the Weddell Sea with ...

New insights into radiative transfer within sea ice derived from autonomous optical propagation measurements [PDF]
The Cryosphere, 2021 The radiative transfer of shortwave solar radiation through the sea ice cover of the polar oceans is a crucial aspect of energy partitioning at the atmosphere–ice–ocean interface.

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
