Abstract
Analysis of tide records from Monterey Harbor for the three-year period 1964-1966 showed that two types of sub-tidal oscillations occur in the harbor having mean periods in the range of 19 to 39 minutes and 1.5 to 2.0 minutes. Their heights, recorded on the tide records, varied from 0.2 to 0.4 foot and from 0.1 to 0.5 foot, respectively. The longer waves occur in trains having durations from a few hours to several days, and have a well-defined seasonal and diurnal frequency of occurrence, being most common during July and between the hours of 1200 and 1600. The shorter waves are recorded almost continuously. The long period waves probably are progressive waves produced by air-pressure fluctuations or by resonance with the ordinary surface waves associated with the coastal sea breeze. The short period waves appear to be either natural oscillations of the harbor or surf beat accompanying swell arriving from the open ocean.
