Ex-US navy commander Victor Vescovo has become the first person to reach the bottom of all four of the world’s deepest ocean trenches.

Victor Vescovo, a former US Navy commander touched the bottom of the Kermadec Trench in the South Pacific Ocean, which is the fourth deepest ocean trench. In his latest adventure on December 13, Vescovo reached a depth of 10,012 meters in an expedition that lasted for nine hours.

Vescovo made the dive inside the DSV Limiting Factor, a dual-seated module developed by Triton Submarines, a company based in Florida. The 55-year-old shared glimpses of his expedition through Twitter where he shed some light on the geology and the marine life in the deepest waters.

With the Kermadec Trench being his newest achievement, Voscovo has also visited the Earth’s deepest point- Challenger Deep in the Mariana Trench (10,925 metres), Horizon Deep in the Pacific’s Tonga Trench (10,817 metres), and the Emden Deep in the Philippine Trench (10,045 metres), the third deepest point.
