Oceanographer Scott Veirs shows us how to listen for whales in Puget Sound, identify their signature sounds and maybe help save them. If Puget Sound has an animal celebrity, it’s the orca — specifically, the southern resident population of killer whales. About 70 individuals divided into three family groups, or pods, make their home in our waters for large parts of the year. Fans from all over the world follow every movement of the southern residents; they mourn every whale death; they rejoice when a new calf joins a pod. These camper-van-sized whales subsist almost entirely on salmon, which they hunt in the murky sea, using only sound. But the clicks, whistles and honks they employ while hunting are also the building blocks of a rich language we’re only beginning to decode. Some elements are understood by whales all over the world, but each pod has its own unique dialect used only among family members.  In this episode of Crosscut Escapes, Veirs tells us about his Orcasound project, which allows anyone with an internet connection to listen for whales and even learn to identify the signature sounds of our cetacean superstars. As we listen, we’re learning more about how orcas behave when we can’t see them — and how we might save them from the human-caused noises that intrude on their watery world.  --- Credits Host: Ted Alvarez Engineering: Karalyn Smith, Piranha Partners Music: The Explorist
