Most energy from ocean waves and tides is ultimately transmitted to the coastal periphery or nearshore zone. The dissipation of this energy creates a complex environment characterized by intense interactions between waves, currents, and sediments. A data acquisition system, using digital techniques, has been designed and used in the laboratory and field; it provides instantaneous-synoptic measurements of the nearshore environment. Using modern computer techniques, the system can efficiently acquire and analyze a tremendous volume of data. Special sensors of the system include: a digital wave gage with self-contained logic circuitry; a vibrating-wire transducer to measure pressures on the bottom; a Savonius current meter; and a photography technique for estimating the density of suspended sediments.
