In this thesis land-fast ice is modelled based on the internal dynamics of sea ice. The region of interest is the Kara Sea, which has a well documented semi-permanent fast-ice cover.

This means that internal ice stresses must play an important role, in addition to the well-known grounding of pressure ridges.
