The Acquisition and Analysis of Wave Data Recorded on a Spar-Bouy Mounted Digital Cassette Recorder.
Abstract
This report concerns the design, fabrication, and operation of a wave measurement system. The system was required to operate without tethering, telemetering, or support from either a vessel or the sea floor. Another requirement was a rapid data processing ability, with a reliable spectral analysis of the wave height data taken during each of several operations. The damped spar buoy which served as the platform for the wave height sensors is described in the report. The wave height sensors were of the capacitor type and their associated electronic circuity is also given in the report. The wave height data was recorded on board the spar on a miniature digital cassette recorder. At the conclusion of each field test, the cassette containing the wave data was returned to the Ocean Engineering (URI) Laboratory for spectral analysis. The report contains an extensive presentation of the computer processing procedures (Fast Fourier Transform, window shading, power spectral density, frequency averaging, etc.).
