Part of: Ocean Wave Measurement and Analysis


A new correction procedure for Shipborne Wave Recorder (SBWR) wave height and spectral data is described. The method is based on a reassessment of the available frequency response measurements using a Froude type frequency scaling. The paper discusses the direct application of the correction function to spectral data as well as describing a method of applying the correction to archive SBWR data which consists of Hs and Tz only. It is found that the new correction gives a considerable improvement in accuracy. This work may be seen as a sequel to the paper by van Aken and Bouws presented at Waves 74 which was based on a more limited data set.
