USGS all-terrain vehicle is equipped with GPS and collects beach topography on Rio Del Mar State Beach, Aptos, CA
October 21, 2014
Photograph shows a USGS scientist navigating an all-terrain vehicle equipped with GPS, collecting topographic data on Rio Del Mar State Beach in Aptos, California. Gathering this type of information helps USGS scientists to document the changes in beach and nearshore morphology (or form and structure), caused by seasonal variations and storms.
