The Boomer and the Pinger probe sonar seismic systems which are used for subsurface investigations in water-covered areas are described. The Boomer is used for deep sediment penetration studies, and the Pinger probe is used for detailed, high-resolution, shallow penetration work. The Boomer produces a low-frequency, high-energy pulse using a high-voltage discharge into an electromechanical transducer which produces an eddy-current plate repulsion. A continuous recording process produces a record of the reflections from the water-bottom and sub-bottom interfaces. The Pinger probe employs a short, high-intensity 12-kc pulse from a crystal transducer. Recording is accomplished by a small, high-resolution Alden helix recorder. A number of examples of records are presented from each system.
