Melting ice and its effect on water levels

It makes sense that the ice cube would float higher in salt water because of the salt water's higher density. Once melted to fresh water the ice cube will take the same volume as before (10cm^3) but it was dispersing only 9.5cm^3 of space when floating so the will rise to account for the additional .5cm^3.
