The technique of digital particle image velocimetry (DPIV) and the related technique of particle tracking velocimetry (PTV) are described. These techniques were extended and applied by the author to the study of surface active chemical films on the mechanics of capillary-gravity waves. The two custom-made facilities for these studies are described along with specialised image processing software developed by the author. Finally, results from a series of experiments are presented which detail the damping of wind waves by surface active films, measurements of wind induced surface drift and the alteration of surface particle trajectories. Results from all three experiments were compared with theoretical predictions.
