Martin, I vote for retiring ICE2WATR and making the other changes that you suggest below.  D.

Currently this is the case for all verification experiments that use pkg/seaice, except for global_ocean.cs32x15/input.icedyn (because that one does not use the PW thermodynamics), so retiring this parameter requires changing all of these verification experiments.

I would like to change the freshwater units within the seaice_growth routine into mass units (and then add my sublimation code), but because of the ICE2WATR=0.92 in the "data.seaice"-files it is impossible to test whether these modifications affect the solution or not (any change to the code will, because the densities are inconsistent with their ratio). So I have the choice of either retiring this parameter, thereby changing the above experiments, or keeping ICE2WATR as it is, but changing the verification experiments anyway. What do you think?
