Highlights
Marine Mammals & Noise
LGL and associates literally "wrote the book" on effects of noise on marine mammals. After years of studies of the effects of industrial disturbance on whales and other marine mammals in the Atlantic, Pacific and Arctic oceans, LGL scientists compiled their information with collaborating partners to publish a comprehensive treatise on the subject (Marine Mammals and Noise, 1995, Academic Press).
