Two arrays of thermistors were installed and operated off San Clemente Island, California, for several months in 1964 and from 5 August 1965 to 16 January 1966. For the latter array, thermistors at 240 and 340 were inoperative after 3 September 1965, but data are available for the thermistors at 1640 and 1740 from 5 August 1965 to 16 January 1966. Spectra of temperature fluctuations show little statistical energy at frequencies above 0.04 cycles per minute, corresponding to periods below 25 minutes. Only rarely was the frequency corresponding to 0.01Ccymin greater than .006 cpm period of 166 minutes or about 3 hours. Some peaks occasionally appear at frequencies higher than 0.04 cpm, but these are small and probably not significant. The spectra for the longest continuous records from 18 November to 27 December 1966 show two peaks, one at approximately 12 hours, and the other between 24 and 32 hours. Results of these experiments emphasize the dominance of tidal periods in thermal fluctuations and indicate that relationships between surface and internal tides should be clearly established. These results are in substantial agreement with those obtained by other investigators in the past decade. Author
