Cover Story

USGS Images Gas Hydrates with 2,000 Kilometers of New Seismic Data on the U.S. Mid-Atlantic Margin
In August 2018, the USGS Coastal/Marine Hazards and Resources Program completed the Mid-Atlantic Resource Imaging Experiment, a three-week cruise that acquired more than 2,000 kilometers of multichannel seismic data between Hudson Canyon and Cape Hatteras on the U.S. Atlantic margin.


Large Underwater Experiment Shows that “Turbidity Currents“ are Not Just Currents, but Involve Movement of the Seafloor Itself
This dramatic discovery, the result of an 18-month-long, multi-institutional study of Monterey Canyon, could help ocean engineers avoid damage to pipelines, communications cables, and other seafloor structures.


Life in Total Darkness–Investigating Underwater Cave Ecosystems
Scientists are using sophisticated cave diving techniques and sampling devices created at the USGS to learn more about what types of life exist in underwater caves along limestone and volcanic coastlines.

Recent Fieldwork
USGS scientists visited more than 20 coastal and offshore locations, studying deep corals off the East Coast, restored beaches and dunes in New Jersey, mine tailings in Lake Superior, and much more.

The Development and Demise of Florida’s Coral Reefs
USGS scientists published a new study in the journal Global Change Biology suggesting that unlike most other reefs, the geological decline of Florida’s reefs preceded modern coral-reef degradation by at least 3,000 years.
