    This book discusses, among many other topics, just how well marine mammals hear, how noisy the oceans have become, and what effects these new sounds have on marine mammals. The baseline of ambient noise, the sounds produced by machines and mammals, the sensitivity of marine mammal hearing, and the reactions of marine mammals are also s: 4.   Understanding Sound in the Ocean. J Levels of underwater noise from human activities—including from ships, sonar, and drilling—have increased dramatically. Those growing levels of ocean noise affect marine animals and habitats in complex ways.

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.

For the 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.

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.

The National Research Council report, Ocean Noise and Marine Mammals, attempted to quantify the world ocean-noise budget between 1 andHz with particular attention to habitats that are important to marine mammals (NRC, b).

This book discusses, among many other topics, just how well marine mammals hear, how noisy the oceans have become, and what effects these new sounds have on marine mammals. The baseline of ambient noise, the sounds produced by machines and mammals, the sensitivity of marine mammal hearing, and the reactions of marine mammals are also examined.

This report is the third in a series by the National Research Council examining the potential effects of ocean noise on marine mammals. Although these reports evolved from very different charges and were generated by separate committees, similar research needs became evident during each study.

Richardson et al. () provided a comprehensive summary of published and gray literature data on marine mammal responses to specific noise sources. Although the literature continues to expand and many valuable new studies have appeared, most recent publications have tended to provide variations on themes rather than new data at variance with the conclusions summarized by Richardson et al.

Ocean Noise—the underwater sound from all types of noise sources, including noise from specific identified sources as well as ambient noise.

For the purposes of evaluating the potential effects of underwater sound on the marine environment, both ambient noise and the noise from identified sources must be considered.

protecting marine mammal habitat and regulating cumulative effects. One approach for protecting marine mammals might be to monitor their populations and initiate protective measures for populations in decline.

However, we cannot estimate trends precisely for most marine mammal populations, and by the time a decline is detected, it may be too late. This report is the third in a series by the NRC examining the potential effects of ocean noise on marine mammals.

Although the three reports evolved from very different charges and were generated by separate committees, many similar research needs became evident during each study.

Ocean Noise and Marine Mammals by National Research Council,available at Book Depository with free delivery worldwide. Chapter 2 describes both natural and human contributions to noise in the ocean and discusses long-term trends in noise levels.

Chapter 3 describes effects of ocean noise on marine mammals, focusing primarily on behavioral changes. Models of marine sound and its effects on marine mammals are described in Chapter 4. Although a few documents on marine mammal sound production and reception date back years, concern about the effects of man-made noise on marine mammals.

An audio collection of sounds made by marine mammals, fish, and technology. Introduction Spectrograms—shown on the right of each image below—are a way to visualize sound, and represent frequency (Y-axis) over time (X-axis). Colleagues and scientists of the Northeast's Passive Acoustic Research Group collected the sounds on this page.

Attention has been drawn to the subject of how ocean noise affects marine mammals by a series of marine mammal strandings, lawsuits, and legislative hearings, and most recently, the report from the U.S. Commission on Ocean Policy. Vessel-generated underwater noise can affect humpback whales, harbor seals, and other marine mammals by decreasing the distance over which they can communicate and detect predators and prey.

Scientists can use these maps, along with other information, to better understand what is happening underwater and where higher levels of human-produced noise overlap with the marine mammals. With these maps complete, NOAA began to push forward on a long-term visionary plan regarding ocean noise effects.

In Marine Mammals and Low-frequency Sound: Progress Sincethe committee noted that the amendments to the Marine Mammal Protection Act (MMPA) addressed some of the issues raised in the NRC report. The amendments introduced two levels of takes by harassment under the MMPA—level A and level B harassment.
