A world 1000 meters beneath the surface: complete darkness, crushing pressure, and freezing temperatures. The deep sea, covering over 90% of Earth's habitat, remains largely unexplored – even more so than the moon. This film follows the technical, scientific, and ecological hurdles faced by deep-sea researchers. Scientists globally collaborate, using over 3000 autonomous floats to monitor the upper ocean for impacts on weather patterns like El Niño and the monsoon, and to understand its role in global climate change and potential solutions for CO2 reduction. In the Okinawa Trough, researchers search for valuable resources like oil, natural gas, and methane, while also working to catalog the millions of unique deep-sea creatures before they vanish.
