About This Lesson
In this episode, marine biologist Ben Williams (University College London & the Zoological Society of London) reveals how AI + bioacoustics can “listen to the reef” to detect hidden signs of recovery. Drawing on 900,000+ underwater sound detections from reefs across Australia, Indonesia, Kenya, Mexico, and the Maldives, Williams explains why crackling shrimp and fish calls can show restoration working—even where visuals fall short. Hosted by Sahil Soni of the POP Movement (India), the conversation explores 15 reef “sonotypes,” fish recruitment surges (500%+ in some cases), and the essential human judgment behind the algorithms. Recorded August 14, 2025, the episode offers science, hope, and action for youth worldwide. The production is edited by Collin Taylor.
