1. So, for example, if you could drag an iceberg to a port that needs  fresh water (before it melts completely) you might have quite a source of fresh water (if you could do this and capture it somehow before it melts. In Canada when my older children were young (they are now 43 to 46 years of age) we went to Banff and Jasper in Canada camping together one summer and we drank fresh melted glacier water that had been frozen for thousands of years. it was really amazing tasting by the way.

    Icebergs form from a variety of processes, yet even though they may be found floating in salty seawater, they are primarily fresh water.
    Icebergs form as a result of two main processes, producing a freshwater iceberg:
    1. Ice that forms from freezing seawater typically freezes slowly enough that it forms crystalline water (ice), which does not have room for salt inclusions. These ice floes are not truly icebergs, but they can be extremely large chunks of ice. Ice floes typically result when the polar ice breaks up in the springtime.
    1. Icebergs are "calved" or form when a piece of a glacier or other land-based ice sheet breaks off. The ​glacier is made from compacted snow, which is fresh water.
