Abstract :
A multifrequency, multibeam acoustic system for tethered near-bottom sediment concentration and size profile measurement in the ocean has been developed. EXADAC, the data acquisition and control section of the system, is described. The system operates with four acoustic beams and three frequencies: 1.0, 2.25, and 5.0 MHz. The data acquisition system consists of a CAMAC crate, a PC/AT-compatible microcomputer, and a 9-track streaming tape drive. The system has been used in two field experiments. Typical data are presented
