New Seafloor Map Only 25% Done, with 6 Years to Go
Beneath the waves, the vast majority of the ocean is unknown. Seabed 2030 is using cutting-edge technologies to fill in the bathymetric blanks and fully map the seafloor.
Mars as a Driver of Deep-Sea Erosion
An analysis of breaks in deep-sea sediment links the geological record to a 2.4-million-year cycle that heats Earth and ventilates our oceans.
What’s Hot in Iceland? A Close Up View of Hotspot-Ridge Interaction
New seafloor magnetic data help scientists retrace the evolution of the Reykjanes Ridge, lending insights into the effects of a mantle plume on mid-ocean ridge organization and evolution.
Submarine Avalanche Deposits Hold Clues to Past Earthquakes
Scientists are making progress on illuminating how undersea sedimentary deposits called turbidites form and on reconstructing the complex histories they record. But it’s not an easy task.
Scientists Quantify Blue Carbon in Bahamas Seagrass
The island nation’s underwater fields store huge reserves of carbon, though not as much as scientists thought.
