1. Story
2. American investor, former US Navy officer and explorer who financed and led the Five Deeps Expedition, reaching the deepest point of all five oceans in DSV Limiting Factor. His Challenger Deep dives - four between 28 April and 5 May 2019, then further dives including June 2020 transects - are what complicate the question 'who went deepest'. Because he dived repeatedly, and because pressure-derived depths depend on the sound-velocity and datum corrections applied, his reported maxima have been quoted variously (about 10,925 m and about 10,928 m appear in expedition material). Not a place.

9. Evidence
10. DSV Limiting Factor (Triton 36000/2) completed four dives to the bottom of the Challenger Deep between 28 April and 5 May 2019 and one dive to the Sirena Deep on 7 May 2019, with maximum depths reported in expedition material as about 10,925 m and about 10,928 m. The vehicle was designed for repeated full-ocean-depth dives.
11. Submersible transects conducted in June 2020 yield a revised Challenger Deep floor depth of 10,935 m (+/- 6 m at 95 percent confidence) below mean sea level. Earlier direct measurements include DEEPSEA CHALLENGER at 10,908 +/- 3 m and its landers at 10,918 +/- 3 m (2012).
