[MITgcm-support] Does the sea ice mass affect the ocean surface pressure?

[Martin Losch]

Hi Gregory,

as with many parameterisations in the MITgcm, you can turn this effect on or off. 
The CPP-flag ATMOSPHERIC_LOADING needs to be defined to make surface loading available and then you need to use the runtiime flag useRealFreshWaterFlux=.TRUE. in data

I am interested if this same potential is used for the ocean equations: i.e. does the ice mass modify the surface ocean pressure? If so, which routine deals with this calculation?
