Oceanography student uses crashing waves on shorelines to study Earth's interior

Scientists have long used the speed of seismic waves traveling through the Earth as a means of learning about the geologic structure beneath the Earth's surface, but the seismic waves they use have typically been generated by earthquakes or human-made explosions. A graduate student is using the tiny seismic waves created by ocean waves crashing on shorelines around the world to learn how an underwater plateau was formed 122 million years ago.
