When pulsed active sonar was found to cause mass strandings of whales, researchers turned to the quieter continuous active sonar for underwater monitoring. In this episode, Brian K. Branstetter (Naval Facilities Engineering Systems Command Pacific) shares his work to find out how this sonar affects killer whales. Associated paper: Brian K. Branstetter, Michael Felice, Todd Robeck, Marla M. Holt, and E. Elizabeth Henderson.
