The Tethys team has partnered with IEA Wind’s WREN Initiative to collect information, or metadata, on environmental monitoring conducted at offshore wind energy projects around the world. By making this information widely available, Tethys and WREN aim to advance global understanding of these effects and progress the industry in an environmentally responsible manner. Annual updates are sought from project developers to ensure the information is reliable and accurate. If you would like to submit a project, please fill out an Offshore Wind Metadata Questionnaire and send it to tethys@pnnl.gov.
