Landfast-ice settings

[anton-seaice]

Dan Atwater has found that turning on Tensile strength (i.e. the plastic response to strain) in CICE works well, and recommends we set the Ktens = 0.2.

To get fast-ice, we would also need to turn on probablistic sea bed stress.

This wouldn't have much impact in the Antarctic, but would grow Arctic fast-ice. There are NSIDC observations (which?) of Arctic sea-ice which include ice-age or ice-type to compare to.
