Well-Posedness of Hibler’s Dynamical Sea-Ice Model
This paper establishes the local-in-time well-posedness of solutions to an approximating system constructed by mildly regularizing the dynamical sea-ice model of {\it W.D. Hibler, Journal of Physical Oceanography, 1979}. Our choice of regularization has been carefully designed, prompted by physical considerations, to retain the original coupled ...

Effect of compressive loading on first-year sea-ice permeability
The permeability of sea ice can strongly affect the dissipation of wave energy into the ice pack. Sea-ice permeability is known to be impacted by the brine volume fraction and the blockage of flow pathways by the freezing of infiltrating lower salinity ...

Impact of Variable Atmospheric and Oceanic Form Drag on Simulations of Arctic Sea Ice [PDF]
Over Arctic sea ice, pressure ridges and floe and melt pond edges all introduce discrete obstructions to the flow of air or water past the ice and are a source of form drag.

Estimates of ikaite export from sea ice to the underlying seawater in a sea ice–seawater mesocosm [PDF]
The precipitation of ikaite and its fate within sea ice is still poorly understood. We quantify temporal inorganic carbon dynamics in sea ice from initial formation to its melt in a sea ice–seawater mesocosm pool from 11 to 29 January 2013.

The effect of landfast sea ice buttressing on ice dynamic speedup in the Larsen B embayment, Antarctica [PDF]
We observe the evacuation of 11-year-old landfast sea ice in the Larsen B embayment on the East Antarctic Peninsula in January 2022, which was in part triggered by warm atmospheric conditions and strong offshore winds.

Benefits and challenges of dynamic sea-ice for weather forecasts [PDF]
Abstract. The drive to develop environmental prediction systems that are seamless across both weather and climate timescales has culminated in the development and use of Earth system models, which include a coupled representation of the atmosphere, land, ocean and sea ice, for medium-range weather forecasts. One region where such a coupled Earth system

The next generation sea-ice model neXtSIM, version 2 [PDF]
Sea ice is a key component of the climate system, and sea-ice models are required to realistically simulate climate, ocean, or atmosphere in general circulation models at high latitudes. In this paper, we present the latest version of the next-generation

Sea-ice dynamics in the Weddell Sea in winter [PDF]
Observations of ice drift received from an array of ARGOS buoys drifting in the Weddell Sea in winter 1986 are described. Wind and current data are also available, permitting derivation of the complete momentum budget including the internal ice stress computed as residuum.

The gravitationally consistent sea-level fingerprint of future terrestrial ice loss [PDF]
We solve the sea-level equation to investigate the pattern of the gravitationally self-consistent sea-level variations (fingerprints) corresponding to modeled scenarios of future terrestrial ice melt.

A dataset of direct observations of sea ice drift and waves in ice
Variability in sea ice conditions, combined with strong couplings to the atmosphere and the ocean, lead to a broad range of complex sea ice dynamics. More in-situ measurements are needed to better identify the phenomena and mechanisms that govern sea ice
