Abstract
Sound is omnipresent in the underwater environment and can be produced by natural (waves, weather, animals) and man-made (shipping, wind farms, oil and gas activities) sources. For marine animals, such as whales, fish and even invertebrates, the auditory senses are very important. To evaluate the soundscape and to manage the marine environment with respect to underwater noise monitoring is very important. For management the impact of noise some options are available. These options need further consideration to be implemented effectively.
