The grounding line in many spots in Antarctica is below sea level: scary :-/

But, given enough time (millennia), the land would ‘rise’ w/o the load of ice on top of it (isostatic rebound*)… but, w/o that ice-load, seas would be 50’s meters-ish higher.

Isostatic rebound: think about it like continents floating on a sea of mantle (so they must have keels)… and ice sheets are like huge foam blocks on top, pushing the whole boat below ‘surface’. That’ll rebound in time.
