Whales and Sonar: Environmental Exemptions for the Navy’s Mid-Frequency Active Sonar Training

open access: yes, 2008
Mid-frequency active (MFA) sonar emits pulses of sound from an underwater transmitter to help determine the size, distance, and speed of objects. The sound waves bounce off objects and reflect back to underwater acoustic receivers as an echo. MFA sonar has been used since World War II, and the Navy indicates it is the only reliable way to track ...
