Beach Profiles for Fire Island Updated January 2017

Elevation data along beach profiles have been measured quarterly since Hurricane Sandy made landfall in 2012.

New Mapping Technology

New technology allows amazingly accurate maps to be made from a collection of images taken with a digital camera mounted on an unmanned aerial vehicle

Severe West Coast Erosion During 2015-16 El Niño

USGS scientists and colleagues document how the winter featured one of the most powerful El Niño climate events of the last 145 years.

Gas Hydrates and Climate

Gas Hydrate Breakdown Unlikely to Cause Massive Greenhouse Gas Release

Advances in Topobathymetric Mapping

Special Issue highlights recent research for understanding the dynamic coastal environment

Storms Batter Santa Cruz, California

A Silver Lining: Atmospheric river brought beneficial sand to beaches

​Do tsunamis pose a threat to the U.S. eastern and gulf coasts?

​Submarine l​andslide tsunamis likely constitute the most frequent and largest amplitude tsunami hazard to the Atlantic and Gulf of Mexico coasts.

Long-lived boulder corals: an oceanic counterpart to tree rings.

Corals help reconstruct historic ocean temperatures, forecast future trends

New Technique Quickly Predicts Salt Marsh Vulnerability

If coastal salt marshes are like savings accounts, with sediment as the principal, Atlantic and Pacific coast salt marshes studied are "in the red"
