Sand and rocks at the beach are always moving and changing the shape of our coast, whether quickly during storms or more slowly during seasonal cycles. One simple way to track these changes is through beach profiling, where the slope of the beach is measured perpendicular to the water line. Sara spoke to Annie O'Connell from the UMass Stone Living Lab, who coordinated a volunteer beach profiling effort along the eastern Massachusetts coast, and also some of the volunteers that have been measuring the slope of Duxbury Beach on a regular basis.
