On this broadcast, we explore scientific research on the Hudson River that uses soundscape recordings and acoustic technologies such as side-scan sonar, a tool inspired by echolocation. The show features excerpts from a lecture entitled Soundscape Indicators of Biodiversity, Ecosystem Function and Human Influences on the Hudson River Watershed provided for the Hudson River Watershed Alliance Breakfast Lecture Series by Aaron Rice from the K. Lisa Yang Center for Conservation Bioacoustics in June of 2021. We also hear a story from naturalist Tom Lake about Atlantic Sturgeon, a massive fish that swims in the Hudson. Music by Trio Kait, Vincent & Vonorn, Kevin Cheli & Tom Law, and DJ T-Rock & Squashy Nice.

Echolocation explores aspects of environmental art, especially the use of bioacoustics in sound art and musical composition. The show dwells at the junction between art, science and natural sound, and features works by artists working in the fields of soundscape studies, deep listening and acoustic ecology. Featured composers include R. Murray Schaffer, Doug Quin, Lisa Walker, Hildegard Westerkamp, Pauline Oliveros, and others. Each quarterly program includes news and updates from fields related to scientific and artistic studies of environmental sound. Submissions of locally recorded and produced pieces are encouraged. https://www.facebook.com/EcholocationWGXC
