“Pretty interesting - I wish they’d elaborated on this phenomenon though. Wouldn’t the gravity caused by the mountain mass itself pull the water down causing a dish, rather than dome, on the oceans surface?”
Nope! Gravity isn’t just perpendiculat to the ocean surface. It would also pull every way perpendicular to the mountan mass and thus the net effect would be a bump.
a clue.......a measured bump......bunches of em too
