The Triton Initiative is researching various environmental monitoring technology and methods to understand how different types of stressors caused by marine renewable energy devices can be tested. The research focuses on the known environmental stressors identified in the State of the Science Report produced by PNNL’s OES-E team. The stressors include collision risk, underwater noise, electromagnetic fields, or changes in habitat. The information gleaned from this research will produce a set of recommendations to inform regulators on how to safely permit marine renewable energy devices bringing the nation closer to meeting climate change goals and reducing dependency on fossil fuels.
