Researchers at the University of Cascadia, in Washington developed multisensors that provide details on the movement of whales. Attached to the aquatic mammals using suction cups, these devices transmit signals that indicate the depth and acceleration of the animals, thus allowing laboratory scientists to have a 3-D visual of their activities in the water.

This new device helps the study of whale behavior. The first results are already beginning to appear. For example, the sensors showed that for food the right whale dives slowly over a ten-minute period or more, while the blue whale attacks at high speed, interspersed with pauses for breathing.
