Man Made Impacts to Man Made Impacts to the Open Oceanthe Open Ocean

There are many kinds of impacts or threats to the open ocean. Some are

natural, like storms, and some are man

made, like pollution. The pictures below show some impacts

of both kinds.

Today we will concentrate on Marine Debris and Noise Pollution

Noise PollutionNoise PollutionNoise PollutionNoise Pollution Marine animals, particularly marine mammals and fish, use sound Marine animals, particularly marine mammals and fish, use sound

for reproduction, feeding, predator avoidance, and navigation for reproduction, feeding, predator avoidance, and navigation (Popper 2003).(Popper 2003).

Marine life uses sound because sound travels 5 times the speed of Marine life uses sound because sound travels 5 times the speed of sound in air. Vision is only useful for tens of meters underwater, sound in air. Vision is only useful for tens of meters underwater, yet sound can be heard for hundreds, even thousands of yet sound can be heard for hundreds, even thousands of kilometers.kilometers.
