From Bats to Submarines: Sonar and Climate Change Solutions

Video 5 of the Echolocation Unit. This segment transitions from bats to human technology by explaining how sonar was developed as a form of echolocation to help ships, especially submarines, navigate in the dark depths of the ocean. Students will learn how sonar has evolved into a tool for environmental protection, helping scientists map the ocean floor, monitor coral reefs, and track fish populations affected by climate change. The segment provides examples of how sonar is used to monitor ecosystem health and guide efforts to protect and restore coral reefs.
