Sea-Ice Dynamics on Triangular Grids [PDF]
Journal of Computational Physics, 2021 We present a stable discretization of sea-ice dynamics on triangular grids that can straightforwardly be coupled to an ocean model on a triangular grid with Arakawa C-type staggering. The approach is based on a nonconforming finite element framework, namely the Crouzeix-Raviart finite element.

Water (Switzerland), 2022 In this paper, a numerical model of the White Sea is presented. The White Sea is a small shallow sea with strong tidal currents and complex ice behavior. The model is the only comprehensive numerical model for the White Sea. It consists of several coupled submodels (for water, ice, pelagic, and sympagic ecology).

Sea Ice Thermohaline Dynamics and Biogeochemistry in the Arctic Ocean: Empirical and Model Results [PDF]
Journal of Geophysical Research G: Biogeosciences, 2017 Large changes in the sea ice regime of the Arctic Ocean have occurred over the last decades justifying the development of models to forecast sea ice physics and biogeochemistry. The main goal of this study is to evaluate the performance of the Los Alamos

Population dynamics of bacteria in Arctic sea ice
Microbial Ecology, 1989The dynamics of bacterial populations in annual sea ice were measured throughout the vernal bloom of ice algae near Resolute in the Canadian Arctic. The maximum concentration of bacteria was 6.0·10(11) cells·m(-2) (about 2.0·10(10) cells·l(-1)) and average cell volume was 0.473 μm(3) in the lower 4 cm of the ice sheet.

Impact of wave-induced sea ice fragmentation on sea ice dynamics in the MIZ
2020<p>The decrease in Arctic sea ice extent is associated with an increase of the area where sea ice and open ocean interact, commonly referred to as the Marginal Ice Zone (MIZ). In this area, sea ice is particularly exposed to waves that can penetrate over tens to hundreds of kilometres into the ice cover. Waves are known to play a

Modelling Argon Dynamics in First-Year Sea Ice [PDF]
Ocean Modelling, 2014 Focusing on physical processes, we aim at constraining the dynamics of argon (Ar), a biogeochemically inert gas, within first year sea ice, using observation data and a one-dimensional halo-thermodynamic sea ice model, including parameterization of gas physics.

Arctic Coastal Sea Ice Dynamics
Offshore Technology Conference, 1974Abstract In the period March through August, 1973, sea ice movement was observed off Barrow, Alaska, on the Chuck chi Sea coast with a land based radar. It is concluded that during the breakup period, July and early August, the ice movement is predominantly determined by ocean currents parallel to the coast and that
