U.N. Study: The Human Effect Of Noise Pollution On The Ocean

Aug 23 2011

The United Nations recently announced that they have started a 10 year study on the possible human effect of noise pollution on the ocean.

The study will look into the possible effects of human noise pollution on marine wildlife, seeing that human activity in the water has grown significantly in recent decades, causing a rise in ocean noise levels. The experiment, starting on August 30, 2011 in Paris, will seek to answer the question of whether or not noise pollution is effecting marine species in a variety of ways, seeing that not a lot of research has been conducted in this field.

It is known that many marine species use sound as a source of communication under the depths of the ocean water. The International Quiet Ocean Experiment (IQOE) will research whether or not a growing suspicion that increasing noise levels cause alternative behavior in marine animals and reduce their quality of life is true, and to what effect.

Research previously estimated that ocean noise has increased by 10 decibals (ten times increase in sound) between 1950 and 1975, leading researchers to wonder what type of increase has occurred since then until now. The increase in underwater noise is understandable, especially considering the fact that sound travels four times faster in water than in air. To what extend manmade sounds are negatively effecting impacting the oceans is not fully known, and thus will be researched in this project.
