Cetaceans and Naval Sonar: Behavioral Response as a Function of Sonar Frequency
This is an international cooperative research program to quantify the behavioral reactions of cetaceans and herring to controlled presentations of military sonar signals at 2 different frequencies (LFAS:1-2 kHz and MFAS:6-7 kHz), and relevant control sounds within Norwegian waters. The ultimate goal...
