[MITgcm-devel] new salt_plume param?

Hi An and co,

my understanding is that the current set of parameters
allows various redistribution profiles shape and reach.

I was surprised not to find one to tune, not the shape, 
but the very intensity of the parameterization.  Did I miss it?

In my tests I added the following, which seems to provide for an 
easy tuning of the salt plume parameterization strength. 
I thought it could be of interest to other users. So, do you mind if 
I introduce a SaltPlumeEfficiency factor in seaice_growth.F to do
             saltPlumeFlux(I,J,bi,bj)=
     &            HEFFM(I,J,bi,bj)/SEAICE_deltaTtherm
     &            *(1-SIsalFRAC)*salt(I,j,kSurface,bi,bj)
     &            *tmpscal1*SEAICE_rhoIce
     &            *SaltPlumeIntensity
It would range from 0 to 1, and have a default of 1. I believe the 
above snippet would be a correct way to do this. Isn't it?

Cheers,
Gael
