Tethys Engineering is a knowledge hub containing documents on marine energy research, development, and deployment. Tethys Engineering supports researchers, developers, and other stakeholders by facilitating the knowledge sharing needed to advance marine energy development. Key features include a documents library, an events calendar, and a photo library. New content is actively collected by a multidisciplinary team of curators at Pacific Northwest National Laboratory and submitted by community members so that Tethys Engineering reflects the latest research, events, and more.
