You’re out to sea on a 355 foot platform, and suddenly one end begins to slowly tip underwater. Should there be a call for evacuation? Are you sinking? Not if you’re on FLIP – the FLoating Instrument...
A candy basslet ( Liopropoma carmabi ) was just one of the specimens Smithsonian scientists collected from the deep reefs of Curaçao , in the southern Caribbean. To study biodiversity far below the...
To explore the deep ocean, scientists rely on numerous pieces of high-tech equipment . This photo gallery showcases some of the remotely operated vehicles (ROVs), submersibles, and other devices that...
A hybrid underwater vehicle combines the best features of an ROV (remotely operated vehicle), which is connected to a ship in order to transmit data and video feeds, and an AUV (autonomous underwater...
This autonomous operated vehicle, known as an ABE (autonomous benthic explorer), will map sites where seafloor earthquakes have occurred—enhancing our understanding of these catastrophic events.
On her maiden voyage the Royal Mail Ship Titanic struck an iceberg in the North Atlantic just before midnight on April 14th, 1912. Dr. Robert Ballard first discovered the ship's wreckage in 1985...
