Audio: Armed with Science 64: Studying the Effect of Sonar on Marine Mammals
Audio by John Ohab
This edition features a discussion with Dave Moretti of the Naval Undersea Warfare Center in Newport, R.I., the principal investigator for the Marine Mammal Monitoring on Navy Ranges program sponsored by the Chief of Naval Operations Environmental Readiness Division. Moretti will discuss ongoing Navy-funded studies into the effects of sonar on marine mammals based on research gathered from Navy ranges where populations of sonar-sensitive whales have been identified. Researchers are analyzing data from prototype passive acoustic tools designed to monitor these animals before, during and after active sonar operations, then combining it with visual and tag data to better understand animals' reactions to sonar.
