“Deep Ocean Search, led by British expert John Kingsford, employed groundbreaking techniques, including powerful sonar and robotics, to locate and recover the £34 million Nazi-sunken silver coin hoard from a record depth of 17,000 feet. The challenging mission, contracted by the UK Ministry of Transport, involved a team of 20 French oceanographers and faced difficult conditions such as deep waters, adverse weather, swells, and currents, with the presumed site located 1,000 miles from the nearest land in the foothills of the mid-Atlantic ridge. The ship, found broken in two and buried deep in seafloor silt, presented additional challenges with layers of mud heaped upon it.”

Uпderwater compaпy Deep Oceaп Search, which iпclυded 20 Freпch oceaпographers, was coпtracted by the UK Miпistry of Traпsport to recover the coiпs from a record depth of 17,000ft – 4,500ft deeper thaп the Titaпic
“Maintaining Secrecy: Although the recovery mission occurred in 2013, it has only now been disclosed to the public. The successful search was conducted by the salvage ship SV John Lethbridge, equipped with a submarine that transmitted the initial images of the wreck after two hours of underwater descent. Oceaneer Maeva Onda, part of the salvage team, described the moment as incredible. The confirmation of the find came when the robot surfaced with coins stamped with the Crown. However, the team encountered serious challenges in recovering the bulk of the hoard due to the unprecedented depths involved. Operating at such depths led to technical difficulties, including pressure, temperature, and repeated dives, causing system breakdowns not previously experienced at depths of 3,000 to 4,000 meters. Despite the challenges, the recovery, commemorated by a plaque left on the seabed, ultimately succeeded.”
