Fabrizio Logiurato, a postdoctoal physics researcher at the University of Trento in Italy, proposed using Google Earth for teaching wave phenomena in a paper published on the arXiv preprint server. Logiurato argues that real-life examples engender more enthusiasm from students compared to traditional drawings of waves.

So take a look for yourself on Google Earth. Scouring the satellite images will reveal many different kinds of waves due to the ocean's interactions with boats, islands and coastlines.
