None more deep.

New Scientist has a picture taken by the world’s deepest-diving robot:

“Nereus is like no other deep submergence vehicle,” says oceanographer Tim Shank of WHOI.

“It allows vast areas to be explored with great effectiveness. Our true achievement is not just getting to the deepest point in our ocean, but unleashing a capability that enables deep exploration, unencumbered by a heavy tether and surface ship, to investigate some of the richest systems on Earth.”

“With a robot like Nereus, we can now explore virtually anywhere in the ocean,” adds project manager Andy Bowen.

It went down to the bottom of the Marianas Trench and did stuff. By itself. Including filming the whole thing.
