Abstract : The naval importance of knowledge of short-period variations in ocean thermal structure is exemplified by the effect of internal waves upon underwater sound propagation patterns. This thesis describes an investigation undertaken to examine some of the characteristics of short-period (.071-.01 cycles/sec) variations of thermal structure in the vicinity of Monterey Bay. Time series bathythermograph observations at 7.0 minutes' interval and to ten hours duration were collected at a position in 65 fathoms near the shoulder of the Monterey submarine canyon. The depths of one-half degree Fahrenheit isotherms were analyzed for power spectral distribution, and comparison of the individual time-series' spectra was made. Variance of depth of selected isotherms over 140-minute intervals was compared with tidal phase, showing maximums of variation occurring immediately after tidal extremes. (Author)
