After this beaked whale was tagged, the device recorded and stored data about the animal's behavior and information about the surrounding ocean environment. Beyond time, depths, and sounds, the tag records temperatures in the ocean surrounding the whale, and the whale?s pitch, roll, speed, and direction. It records sound 192,000 times per second and other information 50 times a second. After 18 hours, the tag automatically pops off the whales and floats to the surface for the researchers to collect.
