The video explores the collaboration between Jacques Cousteau and NASA in the 1970s to use Landsat satellites for measuring water depth from space. This partnership aimed to improve navigation safety by mapping marine landscapes and identifying hazards. The expedition team, including Cousteau, NASA scientists, and divers, conducted experiments in the Bahamas, demonstrating that satellite-derived bathymetry could accurately measure depths up to 72 feet. This work laid the foundation for the field of satellite-derived bathymetry, enhancing maritime safety and contributing to environmental conservation efforts.
