The Bathysphere on display at the National Geographic museum in 2009. The Bathysphere (from Ancient Greek βαθύς (bathús) 'deep' and σφαῖρα (sphaîra) 'sphere') was a unique spherical deep-sea submersible which was unpowered and lowered into the ocean on a cable, and was used to conduct a series of dives off the coast of Bermuda from 1930 to 1934.
Established reports and manufacturer's claims indicate that a handful of submarines are capable of speeds exceeding 30 knots (56 km/h; 35 mph). In 1960, HMS Explorer S30 achieved an underwater speed of over 30 knots. [1]
One of the first unmanned deep sea vehicles was developed by the University of Southern California with a grant from the Allan Hancock Foundation in the early 1950s to develop a more economical method of taking photos miles under the sea with an unmanned steel high-pressure 3,000 lb (1,361 kg) sphere called a benthograph, which contained a ...

One such device is the Cerberus system. AN/PQS-2A handheld sonar, shown with detachable flotation collar and magnetic compass
Sinking rates have been measured in the project VERTIGO (Vertical Transport in the Global Ocean) using settling velocity sediment traps. [13] The variability in sinking rates is due to differences in ballast, water temperature, food web structure and the types of phyto and zooplankton in different areas of the ocean. [ 13 ]
The bird that can achieve the greatest airspeed is the peregrine falcon (Falco peregrinus), able to exceed 320 km/h (200 mph) in its dives. [ 1 ] [ 2 ] A close relative of the common swift, the white-throated needletail ( Hirundapus caudacutus ), is commonly reported as the fastest bird in level flight with a reported top speed of 169 km/h (105 ...
