Underwater Signature Measurement and Control

SAES Releases Underwater Acoustic Pollution: Sources and Biological Impact Study


Humans perceive the underwater noise in a limited way, which has led him to make an abusive use of some systems that perturb the underwater environment. The main human activities that generate Underwater Noise Pollution (UNP) are dredging and construction, drilling and production of oil and gas, shipping, geophysical investigations, active sonars, underwater explosions and oceanographic research. The noise pollution affects the maritime flora and fauna since the moment that the development of habitual behaviour is altered. Pollution levels of a particular sound and its morphological and physiological impact depend on the exposure time and the intensity of the received signal as well as the species.
