Working at a site off Oahu once used as a marine munitions dump, the Army's Roumrs ROV has cleared dozens of pieces of exploded ordnance.
An American ROV has finally retrieved the black box of an Air France jet that crashed in the Atlantic in June 2009, killing all 228 people onboard.
The probes transmitted eerie images of sunken cars, debris, and personal effects, but the Pacific did not give up any missing victims from last month's disaster.
This spectacular sequence is a closer view of the eruption with violent magma degassing events producing bright flashes of hot magma. Lava is blown up into the water before settling back to the seafloor, and large plugs of lava flow rapidly down the slope. In the foreground is the front of the Jason remotely-operated vehicle (ROV) with sampling hoses. The area in view is about 6-10 feet across in an eruptive area approximately 100 yards that runs along the summit.
