Popis: A deep draft fishing boat was used to generate internal waves in a glacially-fed Norwegian fjord during August 1995. Data from a CCD camera, and X-band delta-K radar were used to compute the internal wave dispersion relation. The optically derived dispersion relation agreed with theoretical calculations based on nearby CTD casts. The radar observations also showed good agreement with the CTD casts but in addition exhibited a nondispersive feature which may be attributed to nonlinear scattering of the radar signal from the surface roughness.
