Five Deeps Mission


The Five Deeps Expedition is the first to attempt to reach the deepest point in each of the Earth’s five oceans: the Puerto Rico Trench in the Atlantic, South Sandwich Trench in the Southern Ocean, Java Trench in the Indian Ocean, Challenger Deep in the Pacific and Molloy Deep in the Arctic.

  • The expedition will traverse 40,000 nautical miles / 74,000 km in 11 months.
  • By the end of the expedition the sub will have descended through at least 72,000 m / 236,220 ft of water.
  • Up to 50 scientific lander deployments will be undertaken alongside the submersible dives.
  • No human has ever been to the bottom of the Java, Puerto Rico* or South Sandwich trenches.
  • No one has ever been to the bottom of Molloy Deep.
  • No manned submersible has ever been to Challenger Deep more than once.
  • No person has ever been to the summit of Mount Everest and also been to the bottom of the ocean at Challenger Deep, which could occur on this expedition.

The Five Deeps Expedition includes dives to the deepest point in each of the five oceans.

Along the route, we’ll be taking opportunities to dive areas of scientific interest or historical importance. Further information about additional dives will be announced over the course of the expedition.

The Five Deeps include

  1. Peurto Rico Trench – Atlantic Ocean
  2. Java Trench/Deep – Indian Ocean
  3. Challenger Deep – Pacific Ocean
  4. Molloy Deep – Arctic Ocean
  5. South Sandwich Trench/Deep – Southern Ocean
