Detailed Description

USGS scientists use specialized equipment to measure sediment dynamics in nearshore and coastal systems. Access by boat is limited in these areas, so personal watercraft are equipped with GPS and echosounders to collect bathymetric data. Seismic sleds are pulled along transects from the beach across the water to measure changes in sediment type below the water.
