Squid Tracking -- How Do We Do It?

To track squid we use a sophisticated sonar device that emits sound waves down into the ocean from the surface. The sound waves will either bounce off the ocean floor or bounce off the squid if they get between the emitting boat and the ocean floor. We get very precise images of each squid that gets in the way of the sound waves. In fact, we can identify each squid as an individual unique from all squid we have catalogued.
