In light of the growing concern about the relationship between human-made noise and the behavior of marine mammals, which can lead to mass strandings and fatalities, this book provides an objective and responsible analysis of the challenges associated with regulating underwater noise. It highlights the existing regulatory gaps and the scientific uncertainties that exist in this field. The book is aimed at a broad audience, including policymakers, acousticians, biologists, environmental activists, legal experts, oceanographers, as well as professionals from the shipping, engineering, and offshore industries. It is an essential work for government agencies, regional institutions, universities, and international organizations.
