Cousteau and two technicians spent 31 days living and working underwater at Aquarius Reef Base. Filmmakers and researchers from Florida International University, Northeastern University and MIT also joined him for two-week-long stretches during the expedition.

The 460-square-foot pressurized lab sits 63 feet below the ocean’s surface in the Florida Keys National Marine Sanctuary with bunks for six. It’s owned by the federal government and operated by Florida International. It allows its inhabitants to scuba dive for up to nine hours without needing to resurface or undergo decompression.
