Some deserts have fresh water and others have salt water. Some deserts have both.
It depends on the temperature of the water. If the fresh water is warmer, then it will melt quickest in the fresh water. If the saltwater is warmer, then it will melt quickest in the saltwater. If the water is frozen (regardless of saltwater or freshwater), the ice won't melt at all.
It doesn't make a difference weather it is saltwater or freshwater because they will cool at the same rate it is just that when saltwater evaporates it will leave the salt particles behind.
