The Coherent Acoustic Sediment Profiler (CASP) was developed under Army Corps of Engineers funding to make cm-scale measurements of 3 component velocity vectors and sediment mass profiles to study sediment transport dynamics in the nearshore environment. The instrument was successfully deployed at the Duck94 nearshore experiment at Duck, NC to determine turbulent properties of the wave and mean current forced bottom boundary layer. The CASP was mounted on an instrumented sled which was moved across the nearshore each day, defining the vertical structure of the mean currents and wave-forced sediment transport.
