The Future is Now for DeepSea Mining By Maggie L. Merrill Deepsea mining for sand, gravel, diamonds, oil and gas as a byproduct of oil has been conducted for many years. In the 1980s there was a flurry of investment and excitement about the prospect of mining the sea floor for manganese nodules. It turned out that the land-based sources for the contents of the nodules was well supplied and the economics of extraction at sea was not sensible at that time, however this may change. While expensive, diamond mining off the coast of Africa is well underway and dredging operations for sand and gravel continues all over the globe driven by increasing construction activities. There is a renewed interest and investment in deepsea mineral mining. 22 MTR January 2007
