The Port of Vancouver has a program designed to study the impact of shipping noise on the local population of southern resident killer whales; this includes trials to slow down ships and see if that lowers the noise and helps the whales to find food.
This is a fantastic resource to dive into the specifics of how noise travels underwater, and how it impacts marine life. Click on their "audio gallery" to get a sampling of what typical ocean noises sound like, from snapping shrimp to air gun blasts.
This is the nonprofit research initiative co-run by Rob Williams, one of the scientists featured in this TED Talk. They have a focus on how ocean noise affects whales and dolphins in British Columbia. Their website features a video narrated by author Douglas Coupland.
This talk was presented at an official TED conference. TED's editors chose to feature it for you.
