This paper takes a new look at the high-frequency range of the wave spectrum. The analysis is based on data sets from two recent field campaigns offshore Portugal and Crete carried out in the MAST II WAVEMOD project, data from the WADIC experiment in the North Sea, and deep-sea data from Haltenbanken and Vo̸ringplata˚et offshore Norway. In addition, we also show spectra obtained by spectral inversion of ERS-1 SAR imagery. The influence and calibration of wave-measuring instrumentation and the use of wavenumber spectra when comparing spectra from shallow water is emphasized.
