Because sea ice controls the surface heat and momentum exchange, light transmission and buoyancy fluxes in the water, its properties profoundly affect regional boundary layer characteristics and biological activity in the polar oceans. Quantifying such effects, however, is complicated by large spatial and temporal variations in ice properties which cannot adequately be resolved by direct observations alone. Present remote sensing data furnish only indirect information on the fundamental properties and processes needed to characterize a sea ice cover and its interaction with the atmosphere and ocean. Nevertheless, satellite and buoy data must provide the basis for future monitoring and the prediction of regional effects. Achievement of this goal depends on the availability of physical models that can translate routine remote sensing information into quantitative data on basic properties such as thickness, temperature, salinity and structure. In this paper we examine recent advances made in understanding and modeling the evolution of sea ice, both locally and on larger scales. Particular attention is given to the thermal, mechanical and optical properties of the ice as determined from field, laboratory and theoretical work.
