EXPEDITION

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

EXPEDITION OVERVIEW

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.

DIVE SCHEDULE

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.

Deep Dive 1 – November ’18

ATLANTIC

The first Deep dive takes us to the Dominican Deep in the Puerto Rico Trench. At over 6,000m this is our first dive into the Hadal Zone.

DEPTH: 8,408 m / 27,585 ft

Deep Dive 2 – January ’19

SOUTHERN

Deep dive two is to the South Sandwich Trench in Antartica. It is the only sub-zero Hadal Zone on Earth.

DEPTH: 8,183 m / 26,847 ft

Deep Dive 3 – March ’19

INDIAN

The Java Trench / Deep is a largely unexplored Hadal trench and is the location for our third Deep dive.

DEPTH: 7,290m / 23,917ft

May ’19

PACIFIC

Deep Dive 4

Challenger Deep in the Mariana Trench is the deepest place on Earth, considerably deeper than Everest is high. It is the penultimate Deep.

DEPTH: 10,925m / 35,843ft

August ’19

ARCTIC

Deep Dive 5

The near-freezing waters of Molloy Deep, west of Svalbard in the Abyssal Zone, will be the fifth and final Deep dive.

DEPTH: 5,573m / 18,284ft

Additional Dives

Dates to be announced

Supplemental to The Five Deeps, the crew will be taking advantage of opportunities along route to survey and dive on sites of historical importance or scientific significance. Information about these dives will be published as the Expedition progresses.
