> Ice is less dense than water and as it melts there is a volume decrease, so one would expect a decrease in the ocean level. Ignoring thermal issues and salt/freshwater, floating ice melting won't do anything to the sea level. It's lower density, but it's floating in such a way that it's only displacing a volume of water which weighs as much as it does.
