Large scale diffraction
While viewing a lake, there was a fallen tree in it and waves heading perpendicular to it. It left a pattern behind it which looked like light diffraction, which is the cause of iridescence and coronae. Diffraction is when waves bend around an obstacle and interfere with other light waves, some cancel each other out and others amplify each other.

I wonder whether such patterns can be seen on an even larger scale at sea by satellite? I'm thinking of where two opposing currents meet around a headland or similar. Wonder whether there is anything on Google Earth?
