Data holding centreProudman Oceanographic Laboratory
CountryUnited Kingdom  United Kingdom
Time periodFrom December 1987 to October 1989 (with some gaps); from April 1990 to February 1992

Spectral wave data parameters


Wave recorders; sea level recorders


One dimensional wave spectra were measured using a pressure transducer in approximately 10 metres of water at West Bexington, Chesil Beach, Dorset. The pressure transducer was mounted in a tripod, level with the seabed. The instrument cable was linked to the shore and interfaced to a small computer. Pressures were averaged every 0.5 seconds over 1024 seconds. Average water height over this period was also computed. Wave spectra were computed from the 2048 pressure readings, and corrected for pressure depth attenuation using Classical Linear Theory. This analysis was carried out every 18 minutes. Data were recorded on disk if the significant wave height was over 2.5 metres, or if the time was 0000h, 0130h (i.e. in 90 minute steps). The accuracy of the pressure readings was better than +/-1 per cent.
