Delicate Maneuver

February 23, 2019

Alvin Expedition Leader Todd Litke maneuvers the submersible off the deck of the research vessel Atlantis while the ship’s chief engineer, JT Walsh, looks on. The large A-frame on Atlantis is specially designed to lift the sub’s 40,000-pound bulk off the deck, swing it out over the water, and gently lower it down—and to reverse the process at the end of a dive.
