The deep sea, covering approximately 65% of Earth's surface, has long been considered a biological desert. In this extreme environment—particularly in the hadal zone at depths greater than 6,000 ...

The hadal zone, which extends from 6 to 11km (20,000 to 36,000ft), is a forbidding place, characterised by complete darkness, crushing pressure and near-freezing temperatures.

Earth’s hadal zone includes marine regions 19,700 to 36,000 feet (6,000 to 11,000 meters) below sea level. The reference to the Greek god of the underworld, Hades, is not coincidental—these ...

Life isn’t easy in the hadal zone. The deepest region of the world’s oceans—stretching more than 6,000 meters (19,700 feet) below the surface—the zone is home to pressures up to 1,100 ...
