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

[Malte Jansen]

You should then also set
selectP_inEOS_Zc=2,
which makes sure that the EOS uses the the actual pressure at the z* level, as opposed to the pressure at the reference depth of the z* level. For thick ice this starts to matter significantly.
