CODAR data in the form of vector displays overlaid on top of maps
of the coverage area. They also merge satellite-derived sea surface
temperature images with surface current maps and provide these
images online as well. This site contains an excellent tutorial
covering the principles of surface current measurement through
This site contains animations of recently measured CODAR vectors
