Remotely Sensed Wave Spectra from Joint North Sea Experiments II.

Abstract:

The amount of available remotely sensed wave data, obtained by a Helium-Neon laser profilometer in Joint North Sea Experiment II JONSWAP II, has been quite limited because the signal emitted from the laser profilometer, to say the least, was very noisy throughout the whole airborne experiment. Fortunately, among the very few flights whose data was relatively less noisy, steady offshore wind conditions were found to exist for the single flight on September 19, 1973. Wave spectra calculated form wave data obtained by this particular flight are presented in this report. Due to the lack of strong current gradients in the experiment area, the feasibility of inferring currents by using the technique proposed by Huang, et al. 1972 could not be appropriately investigated. However, this particular technique has been included in this report as an Appendix for reference purposes. Author
