[MITgcm-support] sea ice for global_oce_biogeo_bling

[Manfredi Manizza]

Hi Isa,

just for your reference, having used that physical set-up for other 
studies,  it does not has full Arctic Ocean (although I am sure you are 
looking a the
the other pole) that stops at 75 N so then you might run into numerical 
problems due to the lack of balance of fluxes of heat, sea-ice and so 
forth later.

The sea-ice cover is prescribed from gchem (not even the physics) even 
for gas exchange and to mask the solar radiation vertical propagation
as done in the verification experiment you started got as baseline run.  
I think it would be st best to use it "as is" and then  use it as test 
bed for
new bgc processes to implement in Bling given that it is global and 
cheap to run.

I am sure Martin & Co might give you a more detailed and in-depth answer 
(and probably say that I am wrong) about that
but I have the feeling that is not the most suitable set-up for the 
implementation of a sea ice model stable to run.

Maybe using the LLC90 set-up with Bling could be another option given 
that the sea-ice model is already implemented in the physics
as it is. So it would be a matter of working on compiling the Bling code 
with it and test it.

I hope this helps.

Cheers
Manfredi
