His lab’s sound research has become the groundwork powering Whale Safe, a new mapping and analysis tool launched in September of 2020 that overlays whale and ship location data to reduce fatal collisions. We sat down with Baumgartner to discuss how passive acoustics studies have evolved over the years at WHOI, and how Whale Safe is a great way to utilize this research. How does your passive acoustics data help Whale Safe work? How will Whale Safe mitigate animal mortality from ship strikes? Whale Safe is a concept that hasn’t been tried anywhere before.
