An instrument, the Cyclesonde, is described which consists of a buoyancy driven platform with a recording package containing sensors for pressure, temperature, current speed, and current direction. The Cyclesonde makes repeated automatic round trips

Directional reflectors for use with commercial omnidirectional underwater acoustic transducers are described herein. The reflectors are easy to construct, inexpensive, and exhibit none of the ringing characteristics found so frequently with metallic

This paper presents some recent results of experiments conducted to investigate nonspecular acoustic echoes from the edges of underwater objects. When energy is incident at the critical angle, it has been found that ordinary refraction theory can be
