In this video, Princeton researchers Frederik Simons, associate professor of geosciences, and Guust Nolet, the George J. Magee Professor of Geoscience and Geological Engineering, Emeritus, discuss the origins and development of MERMAID and Son-O-Mermaid, instruments that detect and record sound waves in the ocean created by distant earthquakes. Just as a CAT scan can enable physicians to "see" inside the human body, geologists can use earthquake data to survey the interior structure of the planet. With two-thirds of the Earth covered by water, MERMAID and Son-O-Mermaid are among the few instruments able to record earthquakes in the ocean.
