This set of online oceanography activities helps students learn about ocean waves and El Niño-Southern Oscillation (ENSO). The wave module addresses wave anatomy, global and local waves and their relationship to wind, and the properties of tsunamis. Activities in the ENSO module include simple calculations, discovery learning, satellite imagery, simulations, animations and drawings to present relationships between atmospheric and oceanic processes. Multiple choice self-tests are included. Provided by California State University, Los Angeles.
