When scuba diving, will my neutrally buoyant
position 10 metres below the surface remain the same relative to
the sea floor, or the sea surface as the moon causes the tide to go

of the water, that position remains the same relative to
the surface of the water, not relative to the sea bottom,
since density increases with depth (with distance from
