Flooding from Below: The Unseen Risks of Sea Level Rise
Researchers demonstrate a method for assessing how rising seas could raise groundwater levels, potentially transmitting flood hazards far inland.
Two ROVs to Join the U.S. Academic Research Fleet
The midsize remotely operated vehicles, supported by federal grants, will help meet growing demand for submersible research vehicles.
Tiny Icequakes Ripple Through Greenland’s Largest Ice Stream
Seismologists made an accidental discovery on the Northeast Greenland Ice Stream, changing the way glaciologists understand how ice moves.
Great Barrier Reef Corals Hit Hard by Marine Heat Wave
Extreme heat pushed even resilient corals in the Great Barrier Reef to the brink, limiting recovery.
A Seafloor Spreading Slowdown May Have Slashed Sea Levels
Between 15 million and 6 million years ago, a drop in ocean crust production may have lowered sea level by 26–32 meters.
Coastal Dynamics Revealed by Satellite Salinity Data
One decade of high-quality satellite salinity observations provide valuable insights into the complex dynamics in the Mid-Atlantic Bight.
Arctic Ice Is Getting Smoother and Moving Faster
A decrease in pressure ridges over the past 3 decades is making the ice more uniform, with unclear consequences.
Ancient Climate Reconstruction Links Past and Future
A new map of climate conditions during the Pliocene epoch—the last time Earth’s carbon dioxide concentrations hit 400 parts per million—could offer clues about possible climatic changes in store for the 21st century.
An Upgraded Alvin Puts New Ocean Depths Within Reach
The newly retooled submersible, which has already returned fascinating new findings from Earth’s watery depths, is opening more of the deep ocean to direct human exploration.
