Abstract : A simple system was designed to collect wide-angle reflection records in order to investigate the interval sound speeds of the sediment layers in the ocean. The system consisted of a frequency modulated receiver, a cut-to-channel Yagi antenna, and a sonobuoy, used in conjunction with a precision sonic profile recorder and a triggered sound source. A computer routine for reducing the data was obtained and modified for compatibility with the system and use on the IBM 360/67 computer. The system was designed to be both inexpensive and simple to use without any loss of accuracy. (Author)
