6.3. Ice dynamics¶
The dynamics (force balance) of grounded ice can be chosen in the run-specs header by the parameter
0: Ice flow velocity set to zero everywhere (static ice).
1: Shallow-ice approximation (SIA) (e.g., Greve and Blatter ).
MARGIN controls how the grounded ice can extend into the sea:
1: Ice extent strictly restricted to land area (“hydrophobic mode”).
2: Formation of marine ice possible.
3: Formation of marine ice and ice shelves possible.
In case of
MARGIN = 3, ice shelves (floating ice) are included and modelled by the shallow-shelf approximation (SSA; e.g., Greve and Blatter ).
The detailed settings are controlled by additional parameters as described in the run-specs headers.
