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"

How does seagrass impact wave energy?

This paper describes field and model data used to quantify the effects of submerged aquatic vegetation on wave propagation in a back-barrier estuary.

What's Drifting Beneath Kauai's Ocean?

Understanding just what Kauai's reefs are exposed to, and for how long, may help explain why some corals here have succumbed to black band disease.
