The next generation sea-ice model neXtSIM, version 2 [PDF]

Geoscientific Model Development
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

The gravitationally consistent sea-level fingerprint of future terrestrial ice loss [PDF]

, 2013
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.

Wave dynamics features in a sea ice area

Ukrainian Antarctic Journal, 2003
On a base of developed hydrodynamic models the reflecting capacities of edges, cracks and ice field breaks are studied when the surface waves pass through them. It was investigated the ice flexural rigidity and compression effects on the spatial distribution of wave disturbance amplitudes and bend stresses of the ice cover on both sides of the examined

A dataset of direct observations of sea ice drift and waves in ice

Scientific Data, 2023
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

The effect of sea-ice loss on beluga whales (Delphinapterus leucas) in West Greenland [PDF]

, 2010
An aerial survey was conducted to estimate the abundance of belugas (Delphinapterus leucas) on their wintering ground in West Greenland in March–April 2006 and 2008.

A Stochastic Dynamical Model of Arctic Sea Ice

Journal of Climate, 2017
The noise forcing underlying the variability in the Arctic ice cover has a wide range of principally unknown origins. For this reason, the analytical and numerical solutions of a stochastic Arctic sea ice model are analyzed with both additive and multiplicative noise over a wide range of external heat fluxes Δ F0, corresponding to greenhouse gas ...

Influence of Mass Diffusion in Sea Ice Dynamical Models [PDF]

Journal of Physical Oceanography, 2004
The mixing of floes of different thickness caused by repeated deformation of the ice cover is modeled as diffusion, and the mass balance equation for sea ice accounting for mass diffusion is developed. The effect of deformational diffusion on the ice thickness balance is shown to reach 1% of the divergence effect, which describes ridging and lead ...

Arctic sea ice mass balance in a new coupled ice–ocean model using a brittle rheology framework [PDF]

The Cryosphere, 2023
Sea ice is a key component of the Earth's climate system as it modulates the energy exchanges and associated feedback processes at the air–sea interface in polar regions.

Can uncertainties in sea ice albedo reconcile patterns of data-model discord for the Pliocene and 20th/21st centuries? [PDF]

, 2014
General Circulation Model simulations of the mid-Pliocene warm period (mPWP, 3.264 to 3.025 Myr ago) currently underestimate the level of warming that proxy data suggest existed at high latitudes, with discrepancies of up to 11°C for sea surface ...

Thermodynamic and dynamic contributions to the abrupt increased winter Arctic sea ice growth since 2008

Environmental Research Letters, 2023
The area of Arctic winter sea ice growth (WSIG) has expanded dramatically since winter 2008. Yet the thermodynamic and dynamic contributions to the abrupt increase in WSIG remain unclear.
