Density and expansion are very interesting factors. I notice when one freezes water in a sealed container there is a fair bit of expansion. It is supposed to happen at 4 degrees Celsius which is 39.2 degrees Fahrenheit.
If there was a significant volume of water cross this expansion point wouldn't the action of enough of it cause the water in the in the oceans to swell?
Isostatic recovery variations could be far less immediate than crossing a thermal expansion point. Then there is the water to salt ratios to consider. It does become quite a complex model.
