Jim worked with Hans Van Tilburg of NOAA and Terry Kerby of the University of Hawaii's Undersea Research Lab to make dives in July 2013 that discovered the long-lost, 1946 scuttled wreck of the Japanese aircraft carrier submarine I-400. Here he takes a quick moment to pose inside the Pisces submersible during the dive with Terry Kerby at 2,300 feet (Hans Van Tilburg).
