Ocean Twilight Zone

The twilight zone stretches around the world’s ocean, from the Arctic to the Antarctic, just beyond the reach of sunlight. At approximately 200 to 1000 meters deep, it’s cold year-round and the pressures are extreme—as much as 1,500 pounds per square inch. The twilight zone is also one of the largest living spaces on the planet, making it a difficult place to study and understand.
