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

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

A material coordinate treatment of the sea–ice dynamics equations
Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 1998A finite element algorithm is constructed for a material coordinate formulation of the equations of sea-ice dynamics, using quadratic elements and fully implicit time steps. The material coordinate description allows the nodes of a fixed finite element mesh to define the same material elements as time proceeds, which avoids interpolation of nodal ...

Four sea ice dynamics models (elastic-plastic, viscous-plastic, elastic-viscousplastic, and anisotropic elastic-plastic) are reviewed, with the goal of introducing common terminology and notation. Thickness distribution is used to describe ice conditions, which are also approximated by a two-layer model and generalized by an oriented thickness ...

Publisher Summary This chapter discusses various aspects of the modeling of sea-ice dynamics. Large areas of polar oceans are covered with a thin, variably thick layer of ice formed mainly from freezing seawater and accumulated snowfall. The understanding of the dynamic characteristics of the ice cover is important for understanding air–sea ...

A continuum anisotropic model of sea-ice dynamics
Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2004Summary: We develop the essential ingredients of a new, continuum and anisotropic model of sea-ice dynamics designed for eventual use in climate simulation. These ingredients are a constitutive law for sea-ice stress, relating stress to the material properties of sea ice and to internal variables describing the sea-ice state, and equations describing ...

A Dynamic Thermodynamic Sea Ice Model
Journal of Physical Oceanography, 1979Abstract A numerical model for the simulation of sea ice circulation and thickness over a seasonal cycle is presented. This model is used to investigate the effects of ice dynamics on Arctic ice thickness and air-sea heat flux characteristics by carrying out several numerical simulations over the entire Arctic Ocean region.
