There are many comments in the ice_shelf code to "potential temperature". This makes me nervous when MOM6 is now using Conservative Temperature and Absolute Salinity. So the question is whether the ice_shelf code been properly updated to TEOS10 usage? If so, then the comments need to be updated to reflect this point. If not, then the updates need to be done.
