Abstract

Abstract:

Used sea-ice temperature,salinity and density data from Chinese Antarctic Expedition and the Cox and Weeks formula to calculate porosity in ice,the vertical profile of porosity in ice is calculated. Then the vertical profile of sea-ice thermal diffusivity is obtained by establishing an optimal control model about distributed parameter system. According to seven assumed relations of sea-ice thermal diffusion and porosity,the best relation between the diffusion and porosity is identified. In order to illumina...

Key words: sea ice, porosity, optimal identification, numerical simulations, Antarctica.
