Deep-Sea Mining May Have Deep Economic, Environmental Impacts
A new report supports the creation of a compensation fund for nations that rely on terrestrial mining, but it fails to dispel environmental concerns over deep-sea mining.
Oceanic Changes Correlate with Methane Seepage
Changes in sea level and organic carbon burial may have affected seafloor methane seepage over the past 150 million years.
Search for MH370 Revealed Ocean Crust Waves
Efforts to recover the missing airplane produced high-resolution bathymetry of the southern Indian Ocean that raises new ideas about how ocean crust forms.
Volcano Monitoring Goes Offshore
Offshore observations by cabled ocean-bottom pressure recorders have revealed details of the 2015 eruption of Axial Seamount submarine volcano in the Pacific Ocean.
The Long-Lasting Legacy of Deep-Sea Mining
New research reveals a deep-sea mining experiment that took place 26 years ago still has significant and persistent impacts on benthic life.
A New Global Map of Seafloor Fluid Expulsion Anomalies
The first open-source database of SEAfloor FLuid Expulsion Anomalies (SEAFLEASs) at a global scale reveals their distribution and physical parameters.
Sediments May Support the Mediterranean Megaflood Hypothesis
Millions of years ago, the Mediterranean Sea may have evaporated. A newly identified body of sediments could have been deposited by the giant flood that refilled the basin.
Submarine Canyons Breed Megawaves in Japan
The canyons act like a prism, focusing waves into mammoths of destruction.
