Bikini Seafloor Hides Evidence of Nuclear Explosions
Seafloor mapping has revealed a crater and several shipwrecks persisting 73 years after the world’s first underwater nuclear test.
Scientists Rescue Historical Data Taken on Floating Ice Island
A never-before-published data set from the Cold War could help scientists unravel the mysterious western Arctic Ocean.
How Did We Get Here?
With a discovery made from fossils in the seabed, paleoceanographers and paleoclimatologists began tracing the delicate path between ancient eras and our future.
Tiny Marine Shells Reveal Past Patterns in Ocean Dynamics
A 400,000-year calcium carbonate record from the ocean floor sheds light on deep-ocean circulation and on mechanisms driving climate patterns and atmospheric carbon dioxide concentrations.
Audio Reveals Sizes of Methane Bubbles Rising from the Seafloor
A sensitive underwater microphone captures the sounds of methane, a potent greenhouse gas, escaping into waters off the coast of Oregon. Using this sound, researchers can estimate the bubbles’ sizes.
How Offshore Groundwater Shapes the Seafloor
The MARCAN project, launched last January, is working to fill a gap in our knowledge of how freshwater flowing underground shapes and alters the continental margins.
Seafloor Activity Sheds Light on Plate Tectonics
Scientists in Japan study stress released by oceanic earthquakes in newborn sections of seafloor.
Keeping Our Focus on the Subseafloor
Hard-pressed funding agencies wonder whether marine seismic facilities are worth the investment. A recent survey gives a resounding yes.
Microbes May Thrive in Subsea Permafrost Long After Flooding
Two cores from the East Siberian Arctic Shelf reveal how microbial communities develop over thousands of years as submarine permafrost slowly thaws.
