New research shows ship noise is disrupting harbour porpoises in busy Danish waters 🇩🇰🐬
Their signature “buzz” clicks can be almost halved during periods of heavy boat traffic. Meaning they spend much less time hunting and socializing.

🦭 We have a new paper out! We developed an accessible framework for assessing the risk of collision between seals and operating tidal turbines.
⏭️ We found that most seal tracks moved near the turbine without collision.
