Satellite derived coastlines in western Alaska, collected as part of the USGS Typhoon Merbok Disaster Emergency Recovery Efforts.

Perspective view of horizon mapping and fault attribute detection on two combined three-dimensional (3D) volumes located in the Santa Barbara Channel, offshore southern California. The horizons show various marker beds mapped throughout the volumes, providing insights into the 3D deformation patterns.

Map search display filtered to show recently added three-dimensional (3D) surveys, acquired between 1996 and 1998 within the Gulf of America. These surveys were permitted over 25 years ago and are therefore eligible for public release. The Bureau of Ocean Energy Management protraction areas are labeled.

Scientists at the USGS are installing sensors in Wellfleet MA, part of the Cape Cod National Seashore to evaluate the long-term and short-term chemical and geomorphic changes within wetlands. 

As sea-level rise accelerates, vegetation transitions are increasingly observed and USGS scientists are busy assessing those changes. Shoreline at the Cape Cod National Seashore in Wellfleet, MA.
