Running without salinity restoring

[anton-seaice]

For interest & comparison to CM3, I ran the 1deg ryf for 1 year without salinity restoring.

Similar to CM3, the salinity rapidly drops to 0 at the mouth of the Amazon river:

It does similar things at other river mouths

Thanks @anton-seaice, glad it didn't blow up, and its given us what we similar to what we saw in CM3 relation to the Amazon outflow, and other locations like the Baltic.

Just adding some notes from Matt Harrison's talk yesterday. He spoke about two implementations:

1. using a dynamic land model, with code modifications at the coupler level (FMScap) in https://github.com/MJHarrison-GFDL/coupler/tree/SfcMassBal: P-E calculated in subdomain each coupling timestep; P scaled using target moisture transport convergence - see Harrison et al 2022
2. without land model, with code changes in ice model (SIS2) in https://github.com/MJHarrison-GFDL/SIS2/tree/intersperse_merge: use pre-computed land storage and river fluxes; P-E calculated in subdomain each coupling timestep; P scaled using target moisture transport convergence and regional land storage

I guess 2. might be feasible with code changes to the mediator? But it seems a biggish job and we'd need a good source of land storage and target moisture transport data.
