A DIGITAL ANALYSIS OF INTERNAL WAVES AT OCEAN STATION 'P'.
Abstract
Methods of investigating internal waves from bathythermograph information are discussed. A series of 651 hourly observations taken at Ocean Station 'P' is analyzed by two methods to determine the characteristics of the internal waves present. One method involves a study of the fluctuations in depth of six selected isotherms; the other involves a study of the fluctuations in depth of the top, center, and bottom of the thermocline. An objective method is used to determine the depths of these features from the bathythermograph data. Spectra of these features are calculated by Fast Fourier transform, hanned and smoothed, and these spectr are compared with previously published results obtained from a difference method of analysis of the same time series.
