Polymetallic nodules containing minerals essential to energy storage lie at the bottom of the Pacific Ocean. In deep-sea mining, a collector vehicle is sent to pick up these nodules from the deep seabed. The vehicle creates a sediment cloud known as a 'collector plume,' seen here in the foreground, that is then carried away by ocean currents.
