Remote exploration: the changing world of satellite communications

In what is a highly data-intensive industry, ships once had to collect seismic and other exploration data and bring it back with them when the ship next docked in port. But, as the search for oil and gas moves into deeper waters, satellite technology is the only realistic option for communication. Simon Watts reports
