Tow icebergs to water-short areas?

The once seemingly impractical idea of towing icebergs from the Arctic and Antarctic oceans to watershort coastal areas now appears to be an ‘exciting possibility,’ according to a recently published report written by Wilford Weeks, U.S. Army Cold Regions Research and Engineering Laboratory, and William Campbell, U.S. Geological Survey, Department of the Interior. Recent developments such as the possibility of using satellite photography to locate suitable iceberg fields, the growing need to counteract thermal pollution, and the development of ‘super’ tugboats make the idea of towing and melting icebergs a more feasible and attractive means of supplying needed water in some areas.

After preliminary assessment of the availability and transportation aspects of iceberg towing, the authors feel that ‘the results of the study are very exciting and that the possibility of delivering ice to coastal sites in Australia and western South America for a cost of less than one cent per thousand gallons is certainly sufficient motivation to explore the idea is considerably more detail.’
