Cover Story

Seafloor Erosion in Coral Reef Ecosystems Leaves Coastal Communities at Risk
A new USGS study of changing sea depths at five large coral reef tracts in Florida, the Caribbean, and Hawai'i, found the seafloor is eroding in all five places, placing coastal communities protected by the reefs at increased risk from storms, waves, and erosion.

Subsea Permafrost and Associated Methane Hydrate on the U.S. Arctic Ocean Margin
A new publication by USGS and BOEM provides the most complete information to date about the seaward extent of remaining subsea permafrost and possible relict gas hydrate beneath the U.S. Beaufort Sea margin at the edge of the Arctic Ocean.


Recent Fieldwork
USGS scientists studied eight locations in California, Florida, Massachusetts, and Panama in the past month, investigating wetland changes after a winter storm, coral reefs, peat cores, and much more.


Coastal and Marine Geology is Airborne!
A number of Coastal and Marine Geology researchers have completed the Unmanned Aerial Systems certification classes held by the Department of Interior Office of Aviation Safety and the USGS Unmanned Aerial Systems program, creating a fast and inexpensive way to make accurate three-dimensional maps and take aerial photos.
