✦ Synopsis

Monitoring the thickness of sea ice is an important tool in assessing the impact of global warming on Earth's polar regions, and most methods of measuring ice thickness depend on detailed knowledge of its electrical properties. We develop a network model for the electrical conductivity of sea ice, which incorporates statistical measurements of the brine microstructure. The numerical simulations are in close agreement with direct measurements we made in Antarctica on the vertical conductivity of first year sea ice.

Arctic and Antarctic sea ice plays a critical role in the global ocean-climate system, as well as in polar biology. Sea ice is a porous composite of pure ice with brine, air and salt inclusions whose microstructure varies significantly with temperature. The fluid transport properties of sea ice cont

Storm surges in the Beaufort Sea present a severe problem for navigation as well as for offshore oil drilling activities. Influence of ice cover on storm surges in the Beaufort Sea is examined making use of a numerical model as well as a set of observations. The automated shallow-water model of Hen
