Today we will concentrate on Marine Debris and Noise Pollution
Marine animals, particularly marine mammals and fish, use sound for reproduction, feeding, predator avoidance, and navigation (Popper 2003).
Marine life uses sound because sound travels 5 times the speed of sound in air. Vision is only useful for tens of meters underwater, yet sound can be heard for hundreds, even thousands of kilometers.
Noise pollution is any man made noise that might be louder
than the natural sounds in the ocean!!!
