In general, the coarsest mean sizes occur in the channels scoured by dredging or tidal action, and the finest in areas where no dredging has occurred and where tidal velocities are at a minimum. Purpose: The purpose of this data layer is to release a digital version of the grain-size data released in the publication Mencher et al. (1968).
