Popis: Recordings of bottom‐pressure fluctuations were made in San Diego Bay in April 1960 and in January 1961 to study the seiche phenomenon. A solion infrasonic hydrophone was utilized as a bottom‐pressure transducer to detect pressure fluctuations over the range of 5‐ to 1600 sec periods. Analysis of the bottom‐pressure records consists of computing relative power spectra estimates and autocorrelation functions after the raw pressure data are handpass filtered. From the relative power spectra and limited theoretical considerations, it was determined that there is an active longitudinal seiche with a second harmonic period of 1450 sec. A description of the solion infrasonic hydrophone is presented along with the recording and analysis system.
