Abstract

In a new application of stereophotography, the three components of the surface current can be obtained directly. The method does not require the deployment of an instrument in the water, or extrapolation of a subsurface measurement to the ocean surface. The method is applied to data collected in the North Sea and the results are shown to be in good agreement with the predictions of linear theory for surface waves. It is anticipated that the technique will have useful applications for measuring surface drift and currents induced by the orbital velocities of breaking waves, which play an important role in air-sea interaction at the ocean surface.
