Race to develop Deepsea manned Submersibles for mineral exploration and Naval Surveillance

The mineral scarcity and rising prices of gold, copper and rare earth minerals is creating great interest among many nations for deep ocean mineral mining. The oceans, which cover seventy percent of our earth’s surface are believed to be able to satisfy our need of minerals like gold, copper, silver, zinc, cobalt and manganese for the next hundred years. There is enough gold on the seafloor to give every person alive nine pounds, scientists estimate. That would be worth about $150 trillion, or $21,000 a person.
