55    C--   By default cdm wind stress under sea-ice is set to the
56    C     same value as it would be if there was no sea-ice.
57    C     This is a placeholder until a more physically-sensible
58    C     stable solution is developed.  Apparently ocean stress
59    C     that is based on sea-ice velocity can cause trouble in
60    C     Arctic Ocean configurations.  This temporary solution
61    C     also corresponds to that adopted by CCSM-2.  For the
62    C     adventurous user who requires ice-modified stress,
63    C     following options are available.
