The world’s first manned expedition to the deepest point in each of the five oceans,
and the ultimate validatation of a unique deep-sea, manned research submersible.
THE FIVE DEEPS
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 French Bathyscape L'Archimede achieved 8,300m in the Puerto Rico Trench on May 6th 1964.
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.
1 We originally reported this figure as 10,928 meters. As is common practice, following an extensive review of bathymetric data, and multiple sensor recordings taken by Limiting Factor and the three landers, we have revised this figure to 10,925 meters +/- 4m.
