Reducing underwater noise from commercial shipping
Concern has been raised that a significant portion of the underwater noise generated by human activity may be related to commercial shipping. The international community recognizes that underwater-radiated noise from commercial ships may have both short and long-term negative consequences on marine life, especially marine mammals.
What are the Effects of Underwater Noise Pollution?
In the ocean, many marine mammals and other species rely on their hearing for survival. Sound is critical for communication, navigation, locating prey, avoiding predators and finding mates.
Ocean noise from ships and other human activity is increasingly impacting our marine life. In this article, the effects of underwater noise pollution have been considered and some solutions will be proposed.
