USGS scientists working on FLACC study coastal change, and develop techniques and metrics to measure past, present, and future shoreline change rates along the sandy coasts of the U.S.

In collaboration with Massachusetts Coastal Zone Management Agency (MCZM), SFMG completed a geophysical survey (multibeam echosounder and chirp seismic survey) within Nantucket Sound to characterize the seafloor surface and subsurface. The effort extended coverage in Nantucket Sound along the southern shore of Upper Cape Co

An animation showing tectonic faults across the Eastern Pacific Ocean from space. The San Andreas fault in California is shown in green, and the Cascadia Subduction Zone north of it is shown in yellow. The animation ends at the location of Queen Charlotte-Fairweather fault (in yellow), displaying the latest 30-meter terrain model.

Our Nation’s coastlines are almost 100,000 miles long. These extensive coastal areas stretch from Maine’s Atlantic shores in the northeast, south along the shores of the Gulf of America and insular areas in the Caribbean.

The USGS Woods Hole Coastal and Marine Science Center Aerial Imaging and Mapping group hosted a training workshop on using small uncrewed aircraft system (sUAS) lidar technology. The workshop was taught by Mark Bauer and Matt Burgess of the USGS National Uncrewed Systems Office and Geoffrey DeBenedetto of the USGS Arizona Water Science Center.
