Marine Mammal Populations and Ocean Noise:
Determining When Noise Causes Biologically Significant Effects

The Marine Mammal Protection Act limits noise in the ocean when it disrupts biologically significant behavior, such as reproduction, of marine mammals. This report, from the National Academies, clarifies when changes in behavior rise to the level of being biologically significant.

These series of briefings were for members of Congress and congressional staff only. The report was publicly released on November 11, 2004 and can be found, in its entirety, on the Web site of the National Academies Press.
