Polar-orbiting satellite observations are of fundamental importance to explore the main scientific challenges in the Arctic Ocean, as they provide information on bio-geo-physical variables with a denser spatial and temporal coverage than in-situ inst

The neXtSIM-F operational forecast was upgraded in December 2021, with the following developments:improvements to the rheology, with the neXtSIM model now running the latest version of the Brittle Bingham-Maxwell rheology (BBM). The previous version

We present a new brittle rheology and an accompanying numerical framework for large-scale sea-ice modelling. We have based this rheology on a Bingham-Maxwell constitutive model and the Maxwell-Elasto-Brittle (MEB) rheology for sea ice. The key streng

The thick multi-year sea ice that once covered large parts of the Arctic Ocean is being replaced by thinner and weaker first-year ice, making it increasingly vulnerable to breakup by storms. Here we use a sea ice model to investigate the driving mech

Simulating sea-ice drift and deformation in the Arctic Ocean is still a challenge because of the multi-scale interaction of sea-ice floes that compose the Arctic sea ice cover. The Sea Ice Rheology...

Sea ice is a key component of the earth’s climate system as it modulates air-sea interactions in polar regions. These interactions strongly depend on openings in the sea ice cover, which are associated with fine-scale sea ice deformations. Visco-pl

As sea ice extent decreases in the Arctic, surface ocean waves have more time and space to develop and grow, exposing the marginal ice zone (MIZ) to more frequent and more energetic wave events. Waves can fragment the ice cover over tens of kilometre
