23 January 1960: the Bathyscaphe Trieste just before the record dive. Behind her is the USS Lewis Don Walsh and Jacques Piccard inside the Bathyscaphe Trieste. Project Nekton was the codename for a series of very shallow test dives (three of them in Apra Harbor) and also deep-submergence operations in the Pacific Ocean near Guam that ended with the United States Navy-owned research bathyscaphe ...
Sonar mapping of the Challenger Deep by the DSSV Pressure Drop employing a Kongsberg SIMRAD EM124 multibeam echosounder system (26 April–4 May 2019). Challenger Deep (CD) is the deepest known point in the Earth's seabed hydrosphere, a slot-shaped valley in the floor of Mariana Trench, with depths exceeding 10,900 meters. [1]
General arrangement, showing the key features. Trieste was designed by the Swiss scientist Auguste Piccard, based on his previous experience with the bathyscaphe FNRS-2.The term bathyscaphe refers to its capacity to dive and manoeuvre untethered to a ship in contrast to a bathysphere, bathys being ancient Greek meaning "deep" and scaphe being a light, bowl-shaped boat.

Kelly Walsh dived 11,000m under the ocean to Challenger Deep, 60 years after his father Don Walsh made the journey. He tells Bevan Hurley he’s watched the Titan rescue in ‘horror and sadness’
The deepest point of the trench is more than 2 km (1.2 mi) farther from sea level than the peak of Mount Everest. [a] At the bottom of the trench, the water column above exerts a pressure of 1,086 bar (15,750 psi), more than 1,071 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%.
Examine the book of spiders on the chair to see that the spider's favorite food is the house fly. Use the crowbar on the closed glue can on the table to open it. Use the dry brush on the open glue ...
Jacques' father Auguste twice beat the record for reaching the highest altitude in a balloon, during 1931–1932. [2] The Piccard family thus had the unique distinction of breaking world records for both the highest flight and the deepest dive.

On May 7, 2019, Vescovo and Jamieson made the first human-occupied deep submersible dive to the bottom of the Sirena Deep, the third deepest point in the ocean lying about 128 miles northeast from Challenger Deep. The time they spent there was 176 minutes; among the samples they retrieved was a piece of mantle rock from the western slope of the ...
