Sediment at Seawall Beach

At the Bates-Morse Mountain Conservation Area in September, Emily Chandler ’09 of North Yarmouth, Maine (above), with Dana Oster ’09 of Mercer Island, Wash., and Professor of Geology Mike Retelle, surveys Seawall Beach to monitor the transport and erosion of beach sediment. Here, Chandler calculates the distance from her benchmark location to the water’s edge. Researchers have noticed measurable sand transport along parts of Seawall Beach, and extensive erosion at adjacent Popham Beach.
