For the 119 species of marine mammals, as well as for some other
aquatic animals, sound is the primary means of learning about the
environment and of communicating, navigating, and foraging. The
possibility that human-generated noise could harm marine mammals or
significantly interfere with their normal activities is an issue of
increasing concern. Noise and its potential impacts have been
regulated since the passage of the Marine Mammal Protection Act of
1972. Public awareness of the issue escalated in 1990s when
researchers began using high-intensity sound to measure ocean
climate changes. More recently, the stranding of beaked whales in
proximity to Navy sonar use has again put the issue in the
spotlight. Ocean Noise and Marine Mammals reviews sources of noise
in the ocean environment, what is known of the responses of marine
mammals to acoustic disturbance, and what models exist for
describing ocean noise and marine mammal responses. Recommendations
are made for future data gathering efforts, studies of marine
mammal behavior and physiology, and modeling efforts necessary to
determine what the long- and short-term impacts of ocean noise on
marine mammals. Table of Contents Front Matter Executive Summary 1.
