A submersible that vanished in waters off Canada during a tourism expedition to explore the Titanic could have as little as 70 hours of oxygen left, with a British billionaire among those on board.
In a 2022 interview with CBC News, OceanGate CEO and Founder Stockton Rush said the goal of the repeated subaquatic expeditions is to offer researchers an opportunity to analyze changes surrounding the sunken ship, including the development of coral reefs, decay of the ship’s metal and changes to the ocean’s current.
