I think it would go down... here's why.
When water freezes, it expands. That's what full bottles in a freezer burst, as do pipes in winter. So 1 gram of water occupies less space in the glass (1 ml) than 1 gram of ice.
According to Archimedes' Principle, a floating object will displace precisely as much water as its weight. Which is why a log of wood floats - the water it displaces weighs more than the wood itself.
If 1 gram of ice is floating, it means it has already displaced 1 gram of water. When 1 gram of ice becomes 1 gram of water, it will occupy less space.
As the ice melts, the level of water comes down.

- randallsquared 13y agoYes, it does. As long as it's not resting on the bottom, the bouyancy of the ice underneath the top ice will push a little more of the top ice out of the water. The amount of ice matters for how far out it sticks, but the number of pieces it's divided into doesn't matter.
