The U.S. Offshore Wind Synthesis of Environmental Effects Research (SEER) effort, led by the National Renewable Energy Laboratory (NREL) and Pacific Northwest National Laboratory (PNNL) with support from the U.S. Department of Energy's Wind Energy Technologies Office, is continuing its free, public webinar series to share the latest research on the potential environmental effects of offshore wind energy development. During the webinar, speakers will introduce the offshore wind siting and permitting process in the U.S. Gulf of Mexico, as well as the potential technologies and infrastructure likely to be introduced. Speakers will also describe the potential environmental effects of offshore wind energy development in the U.S. Gulf of Mexico and discuss monitoring and mitigation methodologies, and remaining knowledge gaps and data needs. The webinar will include brief presentations, panel discussions, and audience Q&A.
