A thin line to a deep trench.
Marianas Trench—The cable is nearly as thin as a strand of human hair (inset photo shows a human hair, top, and the cable) and stretches 20 miles (32 kilometers) long, far enough to reach into Earth’s deepest seafloor trench. On an April 2006 expedition to the Marianas Trench, WHOI engineers were set to give the new cable its first test in extreme depths. Ultimately, the cable will be used to relay real-time data and communications between shipboard researchers and a deep-sea vehicle under construction called the Hybrid Remotely Operated Vehicle (HROV). Just 250 microns in diameter, the cable will allow HROV to maneuver at depths of 36,000 feet (10,972 meters) without the drag of heavy cables on traditional deep-sea vehicles.
