Bright narrow V-shaped wakes observed by the NASA/JPL AIRSAR during the Loch Linnhe experiment 1989

During an experiment conducted in 1989 in Loch Linnhe, Scotland, a multifrequency synthetic aperture radar (SAR) image containing several bright narrow V-shaped wakes was obtained during a period of low wind speed. One of the imaged wakes is found to be associated with internal waves generated by a ship that was participating in the experiment. Three other wakes were also imaged which were generated by fishing vessels. The wakes of the fishing vessels are different in appearance to the internal-wave wake generated by the experiment ship. The fishing vessel wakes observed at two different radar frequencies can be explained by the mechanism proposed by Munk et al. (1987)
