Autonomous Undersea Technologies to Vie for New XPRIZE
The competition aims at improved health and understanding of Earth's oceans by spurring teams to devise better robotic technologies for seafloor mapping and exploration.
Antarctic Sediment Plume Disrupts Deep-Water Community
Increased sedimentation from a melting glacier inhibits filter feeders in an Antarctic fjord.
Rising Temperatures Release Methane Locked in the Seabed
New research shows that when ice in the seafloor melts, single-cell organisms metabolize the methane released, preventing the greenhouse gas from reaching the atmosphere.
Researchers Track Underwater Avalanches Like Never Before
Using beach ball–like detectors, researchers set out to determine how sediments, which could contain toxic contaminants, travel through submarine canyons to greater depths.
A Magmatic Seafloor Source at an Ultraslow-Spreading Ridge
An ultraslow-spreading stretch of the Southwest Indian Ridge is thicker than expected: both tectonic and volcanic processes may be feeding the growing seafloor there.
New Insights from Seafloor Mapping of a Hawaiian Marine Monument
New surveys help untangle the complex geologic history of the Hawaiian Archipelago and provide hints about where to seek marine life.
Deep Atlantic Conduit Boasts Longest Billow Train
Some 4000 meters below sea level, swirling patterns of more than 250 consecutive breaking waves up to 100 meters tall stretch through the Atlantic Ocean's Romanche Trench.
Rapid Gas Hydrate Forms Pockmarks in Nigeria's Seafloor
The seafloor in deep water regions off the coast of Nigeria is speckled with pockmarks that scientists suggest were mainly made by the rapid formation of gas hydrate.
Seafloor Changes Above the Tohoku-Oki Earthquake Rupture Zone
Three years after the devastating earthquake, transponders record afterslip deformation on the seabed above the Tohoku-Oki rupture zone.
