Back to the problem of ice being lovely attracted to Greenland. From first principles (Newtonian):
Gravitation: a conservative force from which a potential energy field can be derived.
Ideally, water fills the oceans following a constant iso-potential surface. It will be almost horizontal, but in some places with more gravitational pull, the level will be depressed, and in others, will be higher than average.
This is a static effect. Earth gravity variations will not affect anything that floats over a iso-potential surface because these variations have already been accounted for in the level variations of the iso-surface. Nothing that lies in this iso-potential surface will feel gravitational pull parallel to the iso-potential surface. BECAUSE BY DEFINITION THE GRAVITATIONAL FORCE IS PERPENTICULAR TO THIS SURFACE. And in the case of an ice block, this is balanced by buoyancy force due to the water being denser than ice.
Same happens with earth inertial centrifugal force, proportional to the distance to the earth axis. It can be derived from a potential field, which combined, distorts a little bit the gravitational iso-potential surfaces.
Coriolis inertial force, however, is the tricky one, since this cannot be made a conservative force, it depends on the relative velocity of the ice block with respect to the Earth.
The coriolis force appears in all kinds of interesting problems of the Arctic. I would recommend to read about it rather than quantum mechanics (in the context of the Arctic). It's less attractive to discuss while smoking a joint and looking at your gin-tonic ice cubes sticking at the sides than, say, quantum mechanics paradoxes and dragons.
