[MITgcm-devel] (not so) funny things happen in seaice_lsr and pickups

[Jean-Michel Campin]

Hi Martin & Dimitris,

Is there some metric terms also on CS-grid ?
If not, I would prefer to split the changes:
- to keep the same results adding SEAICE_clipVelocities=.TRUE.
  in the CS-grid set-up, and 
- to change the output for the lab-sea (with the new default,
   => SEAICE_clipVelocities=.FALSE.,) since it will also be affected 
  by the metric terms.
Would you agree ?

Jean-Michel
