Are offshore wind farms detrimental to marine mammals? What happens when we industrialise our seas with massive turbines? Can we balance the urgent need for renewable energy with protecting marine life? These questions take centre stage in our conversation with marine ecologist Dr Stephen Comerford, who is the ORE Marine Biodiversity Officer at the Irish Whale and Dolphin Group. Stephen has years of experience working with both the oil and gas industry and offshore renewables, which makes him the perfect guest to discuss this important topic.

In this episode, we discuss the critical issue of underwater noise during wind farm construction. Stephen explains how pile driving - the process of hammering massive steel tubes into the seabed - creates intense underwater noise that can harm marine mammals. However, there's hope in the form of various noise reduction technologies, from bubble curtains to innovative pile installation methods, though implementing these solutions comes with significant costs and technical challenges.

Looking to the future, Stephen shares his perspective on how offshore structures might create novel marine ecosystems and discusses the crucial role of citizen science in monitoring marine mammals. While acknowledging the environmental pressures our seas face, he highlights how Ireland's new focus on marine planning and management, driven by offshore wind development, could lead to better protection of our oceans. The episode offers a balanced view of how we can pursue essential renewable energy goals while safeguarding marine life.
