Το
βαθυσκάφος Deepsea Challenge αναπτύχθηκε από Αυστραλούς μηχανικούς και ήταν ίσως το μόνο που μπορούσε να αντέξει την άβυσσο της τάφρου -σε βάθος 11 χιλιομέτρων, η πίεση φτάνει τις 1.000 ατμόσφαιρες.

submersible into the Pacific and support divers had detached flotation devices, he began sinking fast, and the cockpit, balmy at launch, began to cool. In the sunless depths about 13,000 feet (3,960 meters) down, bioluminescent creatures likely began flickering into view like living constellations.

submersible is a small vehicle designed to operate underwater. The term submersible is often used to differentiate from other underwater vehicles known as submarines, in that a submarine is a fully autonomous craft, capable of renewing its own power and breathing air, whereas a submersible is usually supported by a surface vessel, platform, shore team or sometimes a larger submarine. In common usage by the general public, however, the word submarine may be used to describe a craft that is by the technical definition actually a submersible. There are many types of submersibles, including both manned and unmanned craft, otherwise known as remotely operated vehicles or ROVs. Submersibles have many uses worldwide, such as oceanography, underwater archaeology, ocean exploration, adventure, equipment maintenance/recovery or underwater videography.
