aphotic

At roughly 3,300 feet below the surface — about 2,000 feet above the sunken ship’s location — even the faintest light has faded, leaving a sunless realm known as the aphotic zone.

The depth is known as the aphotic zone — a part of the ocean where there is little-to-no sunlight, and where there is less marine life than layers above, she said.

The dark aphotic zone is home to plankton and other organisms that could potentially get trapped in filters or experience long-term effects from the brine.

“But I think all in all, they’re getting some net benefits by being deep and out in that aphotic zone,” he said.
