Ice sheet extent and early deglacial history of the southwestern sector of the Greenland ice sheet [PDF]

, 2009
The offshore and coastal geomorphology of southwest Greenland records evidence for the advance and decay of the Greenland Ice Sheet during the Last Glacial Maximum.

Benefits and challenges of dynamic sea-ice for weather forecasts [PDF]

Weather and Climate Dynamics, 2022
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

Winter sea ice export from the Laptev Sea preconditions the local summer sea ice cover and fast ice decay [PDF]

The Cryosphere, 2017
Ice retreat in the eastern Eurasian Arctic is a consequence of atmospheric and oceanic processes and regional feedback mechanisms acting on the ice cover, both in winter and summer.

Antarctic sea ice over the past 130 000 years – Part 1: a review of what proxy records tell us [PDF]

Climate of the Past, 2022
Antarctic sea ice plays a critical role in the Earth system, influencing energy, heat and freshwater fluxes, air–sea gas exchange, ice shelf dynamics, ocean circulation, nutrient cycling, marine productivity and global carbon cycling.

A Computational Fluid Dynamics Model for the Small-Scale Dynamics of Wave, Ice Floe and Interstitial Grease Ice Interaction

Fluids, 2021
The marginal ice zone is a highly dynamical region where sea ice and ocean waves interact. Large-scale sea ice models only compute domain-averaged responses.

Well-Posedness of Hibler’s Dynamical Sea-Ice Model

Journal of Nonlinear Science, 2022
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 ...

On the Damping Time Scale of EVP Sea Ice Dynamics

Journal of Advances in Modeling Earth Systems, 2021
We propose to make the damping time scale, which governs the decay of pseudo‐elastic waves in the Elastic Viscous Plastic (EVP) sea‐ice solvers, independent of the external time step and large enough to warrant numerical stability for a moderate number ...

Sea-ice dynamics strongly promote Snowball Earth initiation and destabilize tropical sea-ice margins [PDF]

Climate of the Past, 2012
The Snowball Earth bifurcation, or runaway ice-albedo feedback, is defined for particular boundary conditions by a critical CO₂ and a critical sea-ice cover (SI), both of which are essential for evaluating hypotheses related to ...

Validity of the wave stationarity assumption on estimates of wave attenuation in sea ice: toward a method for wave–ice attenuation observations at global scales

Journal of Glaciology, 2023
In situ observations of wave attenuation by sea ice are required to develop and validate wave–ice interaction parameterizations in coupled wave models.

Improving the spatial distribution of modeled Arctic sea ice thickness [PDF]

, 2005
The spatial distribution of ice thickness/draft in the Arctic Ocean is examined using a sea ice model. A comparison of model predictions with submarine observations of sea ice draft made during cruises between 1987 and 1997 reveals that the model has the
