The deep sea bed is the last great unexplored realm on our planet. Scientists have begun to find extraordinary ecosystems of creatures down there which exist nowhere else. These develop around submarine hydrothermal vents where mineral-rich water erupts from the seafloor at a temperature of 400 degrees Celsuis. These conditions allow unique and bizzare life forms to thrive but they also create rich mineral resources – such as high concentrations of copper, nickel and gold in the rock. In theory, around the world, trillions of dollars’ worth of metal ores lie on the deep sea bed. That is why a growing number of mining companies are exploring the ocean floor.
In Discovery the BBC’s Science Editor David Shukman joins a team of scientists on the British research vessel, the James Cook. They are investigating a newly discovered life- and mineral-rich ecosystem, five kilometres beneath the Caribbean sea with a robotic submarine.
David talks to some of the mining companies with a
