Restoring Coral Reefs Using Healthy Reef Sounds
An inventive approach to revitalize coral reef habitats involves bioacoustics—the use of natural reef sounds. Researchers play recordings of healthy reefs' unique sounds, which include clicks, pops, and rustles made by various marine creatures. These sounds act as navigational cues for coral larvae in the ocean to find suitable habitats to settle in. The deployment of these sounds in damaged reef areas can guide coral larvae to settle and grow, thereby kickstarting the rejuvenation of the ecosystems and promoting biodiversity.
Protecting Endangered Whales from Ship Collisions
Karen Bakker introduces technological strategies using sound to prevent ship collisions with endangered whales. Ships utilize bioacoustic tracking to detect "whale lanes" by listening for whale songs and determining whale population densities. Obtaining locations of whales in maritime regions such as the Salish Sea, this technology communicates real-time positions to ship captains, allowing them to adjust their courses. This vital innovation protects whale communities by reducing the risk of fatal ship encounters and is especially crucial in regions with critically endangered whale populations.
