On August 9, National Geographic Channel is airing a 'virtual expedition miles below the ocean surface' with Drain the Ocean. The two-hour special, narrated by Star Trek: Deep Space Nine's Avery Brooks, uses CGI and state of the art ocean mapping tech to recreate wondrous geological formations lying below the ocean's surface. These include the Mid-Ocean Ridge (a 40,000-mile-long mountain range that circles the globe) and the Marianas Trench, the deepest place on the planet at 36,000 feet below sea level. The show is produced by Burning Gold Productions for National Geographic Channel.
