What is the deepest diving expedition recorded?
Bathyscaphe Trieste
Trieste is a Swiss-designed, Italian-built deep-diving research bathyscaphe, which with its crew of two reached a record maximum depth of about 10,911 metres (35,797ft), in the deepest known part of the Earth's oceans, the Challenger Deep, in the Mariana Trench near Guam in the Pacific. On 23 January 1960, Jacques Piccard (son of the boat's designer Auguste Piccard) and US Navy Lieutenant Don Walsh achieved the goal of Project Nekton.
Gary Gentile
Gary Gentile is a wreck diver. It has been suggested that Gary Gentile may be the most experienced wreck diver in the world. He has dived on the wreck of the "SS Andrea Doria" (sometimes referred to as the "Mount Everest" of SCUBA diving) over 190 times, and was the first diver to penetrate the first class dining room of the vessel. He was also part of the team of divers, along with Bill Nagle, who recovered the ship's bell in 1985.
