Sort of, but you have to remember than when the ice below the surface melts the water it turns back into will actually occupy less volume than the ice did. This means that the amount of water being displaced by the ice is greater than the amount of water contained within it. Ergo (I hate it when people use that word
) the level of water in the sea
should fall.
But, as you say, there is the ice
above the surface to take into account so it should all even itself out
