Perhaps I’m not a scientist but doesn’t ice expand when it’s frozen and then takes up less volume when it melts,

If fills up the same volume that it displaced.

Think of a glass full of ice, topped off to the rim with water.

When the ice fully melts, there is no increase in the water in the glass. The level stays the same.

Correct. Only with a glacier it is like adding more ice cubes to that glass.

Which is true if when dealing with a free floating iceberg. It is not true regarding glacial ice that is not yet free floating (an iceberg.) Volumes of glacial ice currently moving across land that enter the sea will melt and eventually increase sea levels.

Lets hope that DC returns to a muddy marsh and produces something useful, like oysters or mussels.
