The deepest regions of Earth’s oceans, known as the abyssal and hadal zones, lie at least as far under the water’s surface as Mount Rainier’s peak rises above the land surface. These great depths of 4,000 or more meters make up one of Earth’s least explored frontiers and are home to some of its most extreme environments and habitats.
