So I'm trying to model the process of towing an iceberg from Antarctica to elsewhere to use for fresh water. I hit a dead end trying to find how much of the iceberg would be left. I know it takes 333 J/g to melt ice and the mass of the iceberg is 7 million tons so i know how much energy it would take in total to melt the iceberg. I have also come up with an equation T(x) that represents the temperature of water at a distance x from the equator. I however cannot find out how much heat energy the ocean provides the iceberg. A simpler way to think of this is if a cube of ice was in an open system of water where the water just keeps heating the ice without changing temperature. Any insight such as rate or anything would be really helpful.
