This year’s expedition to the Antikythera shipwreck marks the experimental debut of a new robotic diving apparatus for use in marine archaeology—the Exosuit. Theotokis Theodoulou of the Ephorate of Underwater Antiquities in Greece, and co-director of the Antikythera shipwreck expedition, tries out the Exosuit, which maintains atmospheric pressure inside the suit. The Exosuit allows divers to descend to 1,000 feet, far beyond the reach of SCUBA diving. (Courtesy of Brendan Foley, Woods Hole Oceanographic Institution)
