Towards a physical model of Antarctic sea ice microstructure including biogeochemical processes using the extended Theory of Porous Media
Abstract Predictive numerical climate models include an ocean modeling system as an important module, which comprises the components of ocean and sea ice physics as well as the coupled biogeochemical processes occuring in the ocean and sea ice, respectively. Whereas large‐scale, physical sea ice mod...
