Their cruise was to test three new deep-sea landers, one uncrewed search submersible and the new Rainbow Fish 11,000-meter manned deep submersible, all capable of diving to 10,000 meters. From 25 to 27 December, three deep-sea landing devices descended into the trench.
The outside water pressure increases with depth and so the stresses on the hull also increase with depth. Each 10 metres (33 ft) of depth puts another atmosphere (1 bar, 14.7 psi, 101 kPa) of pressure on the hull, so at 300 metres (1,000 ft), the hull is withstanding thirty standard atmospheres (30 bar; 440 psi; 3,000 kPa) of water pressure.
Challenger Deep in the Mariana Trench, located in the northwestern Pacific, is the deepest known point in the world, reaching a depth of 10,928 meters (35,853 feet). [4] The Pacific also contains the deepest point in the Southern Hemisphere, the Horizon Deep in the Tonga Trench, at 10,823 meters (35,509 feet). [5]
Whereas the Water Cube pool used for the 2008 Olympics was 3 metres (9 ft 10 in) deep, the temporary pool used in 2024 was only 2.2 metres (7 ft 3 in), which commentators suggested made for slower race times. [4] A simplified diagram of the FINA long course swimming pool standard.

The 10-meter dive began in the 1908 Olympics. Diving for women started in the 1912 Olympics, with the 10-meter dive. In 2016, dives performed by competitors in 10-meter world competition included a 3-½ somersault tuck, a 3-½ somersault pike, a 2-½ somersault with 2½ twist, a forward 4-½ somersault, and a forward reverse 3½ somersault.
