I enjoyed this ~20minute documentary by CBC science reporter Monica Kid on noise pollution in the ocean. It provides a synthesis and synopsis of many of the inter-linked issues — from Navy LFA sonar and seismic air guns to boats and ships — with interviews with Arthur Popper, Alexandra Morton, Ken Balcomb, Michael Jasny, and Douglas Wartzoff.

I was particularly interested to hear about some of the potential impacts of noise on fish. It was also interesting to hear from Alexandra about the avoidance of seal harassment devices by resident killer whales in the Broughton Archipelago (2/3 drop in sighting rate) and from Ken about the Bahama strandings.

Thanks to Michael Darling of the Seattle Aquarium for letting me know about this nice piece (high-lighted on “and-the-winner-is” show).
