Scientists verified the presence of sharks by lowering real-time video cameras into the water

An echosounder image shows the interface between warmer, less dense water (light blue) sitting atop colder, denser water below (dark blue)—and a possible internal wave propagating along the interface. (Jesús Pineda, Woods Hole Oceanographic Institution)

Bands of smooth water alternated with bands of rough water can indicate the presence of an internal wave.
