Challenger Deep is the deepest known point in the Earth’s seabed hydrosphere, with a depth of about 11,000 metres. It is found at the southern end of the Mariana Trench in the Pacific Ocean.
It is named after HMS Challenger, whose crew made the first measurements of its depth. Only four vehicles have descended into Challenger Deep: the manned bathyscaphe Trieste (1960), the unmanned Kaikō (1995), the unmanned Nereus (2009)
and the manned Deepsea Challenger (2012).
The cyanotype features some of the fauna dredged up from the sea floor by Challenger.
