ABSTRACT 
Temperature records have been obtained at depths 
of 130, 150, 170, 190, and 250 ft from five buoys in- 
itially separated from one ancther by six miles. Each 
record had a duration of about one day and records for 
three successive days were taken. These records have heen 
analyzed for autocorrelation and power spectrum. The 
power spectrum for a typical record is (180 £°)geg?/eph 
in the frequency range from 0.5 to 12 cph. No lines were 
observed in the spectrum, showing that the temperature re- 
cord cannot be synthesized by a linear combination of 
a few simple harmonic waves.
