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. Go ahead and click on the boat to start an animation. |
