La Minerve S647

February 2020

The French submarine La Minerve, lost to the sea in 1968, played host to the first of Caladan Oceanic’s 2020 Expeditions. The submarine, the location of which was only discovered in mid-2019, rests approximately 30 miles to the south of Toulon, France at a depth of 2,350 m (7,709 ft). The dives to La Minerve followed a series of Sea Trials designed to work-up the systems and personnel after their break from the Five Deeps and Titanic Expeditions which culminated in 2019.

Nekton Expeditions

March & April 2020

Following the cancellation of the planned Nekton Mission due to the Covid-19 pandemic, Caladan Oceanic performed detailed mapping of key points of interest in the Amirante Trench in the West Seychelles. The mapping data captured offers a dramatic improvement in resolution over the best existing data.

Five Deeps Expedition

2018 – 2019

After travelling 47,000 miles and completing 39 dives, the Five Deeps Expedition has reached its successful conclusion: the first manned descent to the bottom of each of the world’s five oceans. Numerous other firsts have been made, including the world’s deepest manned dive in history, to a new record 10,925 meters at the Mariana Trench’s Challenger Deep, as well as the first submersible and pilots to repeatedly dive to the bottom of the ocean.


Back to Titanic


The first dives to Titanic in 14 years, and the first to record the wreck in 4K Ultra-High Definition and 3D. The Expedition yielded valuable data about the current state of the wreck and the speed and nature of deterioration.
