[MITgcm-support] more questions about sea ice

[Martin Losch]

Hi,
Dimitris, this is probably specifically addressed to you.
What are the policies regarding the sea-ice model? Did you aim at using 
as little information from the main code as possible, e.g. grid and 
masking information? I noticed that the masks maskC are not used 
anywhere, so that for example, after calling the seaice model, theta is 
no longer zero over land (doesn't matter, but is ugly), because it is 
not masked in growth.F.
All grid parameters are computed in seaice_init.F from the grid 
parameters of the ocean models, instead of adopting the ocean model 
grid parameters (I know it's a different grid, but still all fields 
could be applied properly). Is this intentional in the sense you didn't 
want to change the sea ice model too much or didn't want any 
interference or is it just because it  was quicker and less error prone 
that way (which I could perfectly understand, because adi and lsr are 
difficult to read, and I wouldn't like to have to modify these 
routines)?

inquisitively,
Martin
