The dynamics of unstable waves in sea ice [PDF]
Scientific Reports, 2023 AbstractWave and sea ice properties in the Arctic and Southern Oceans are linked by feedback mechanisms, therefore the understanding of wave propagation in these regions is essential to model this key component of the Earth climate system. The most striking effect of sea ice is the attenuation of waves at a rate proportional to their frequency.

Rigorous Analysis and Dynamics of Hibler’s Sea Ice Model [PDF]
Journal of Nonlinear Science, 2022 AbstractThis article develops for the first time a rigorous analysis of Hibler’s model of sea ice dynamics. Identifying Hibler’s ice stress as a quasilinear second-order operator and regarding Hibler’s model as a quasilinear evolution equation, it is shown that a regularized version of Hibler’s coupled sea ice model, i.e., the model coupling velocity ...

Role of Ice Dynamics in the Sea Ice Mass Balance [PDF]
Eos, Transactions American Geophysical Union, 2008 Over the past decade, the Arctic Ocean and Beaufort Sea ice pack has been less extensive and thinner than has been observed during the previous 35 years [e.g., Wadhams and Davis, 2000; Tucker et al., 2001; Rothrock et al., 1999; Parkinson and Cavalieri, 2002; Comiso, 2002].

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 CO<sub>2</sub> and a critical sea-ice cover (SI), both of which are essential for evaluating hypotheses related to ...

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

Observations of exponential wave attenuation in Antarctic sea ice during the PIPERS campaign
Annals of Glaciology, 2020 Quantifying the rate of wave attenuation in sea ice is key to understanding trends in the Antarctic marginal ice zone extent. However, a paucity of observations of waves in sea ice limits progress on this front.

Geophysical Research Letters, 2023 Sea ice modulates the energy exchange between the atmosphere and the ocean through its kinematics. Marginal ice zone (MIZ) dynamics are complex and are not well resolved in routine observations.
