About Tethys

Renewable energy sources like wind, waves, and tides can be harnessed to contribute to the growing demand for energy and to power the blue economy. Potential environmental effects must be monitored and mitigated to reduce harm to animals, habitats, and ecosystems and to limit conflicts with existing ocean and land users. To support responsible development, Tethys hosts documents, information, and resources on marine energy, wind energy, and potential effects on wildlife and the environment.

Tethys Mission

Tethys aims to advance marine energy and wind energy research, development, and deployment by improving access to environmental data and information for researchers, regulators, developers, students, educators, and other stakeholders. The collection of documents on Tethys preserves knowledge as the industries progress, provides a foundation for synthesis products, and aggregates reliable information in support of artificial intelligence and machine learning.

Tethys Content

Key features of Tethys include the:

  • Knowledge Base: Documents library with journal articles, conference papers, reports, and more.

  • Map Viewer: Map with a subset of all content that can be identified with a geographic location.

  • Events Calendar: Marine energy and wind energy conferences, workshops, webinars, and more.

  • Marine Energy Metadata: Information on marine energy projects and research studies globally.

  • Offshore Wind Metadata: Information on offshore wind energy farms around the world.

  • Tethys Blast: Bi-weekly newsletter with announcements, events, new content, and news.

  • Glossary: List of terms used to tag content, including definitions and links to relevant documents.

Tethys is also home to several international and U.S. research efforts dedicated to studying marine energy and wind energy’s environmental effects and sharing the state of the science:

These groups have developed several tools and resources to support the marine energy and wind energy communities, including:

Tethys Team 

Tethys is actively curated and maintained by the Pacific Northwest National Laboratory (PNNL) and sponsored by the U.S. Department of Energy Water Power Technologies Office and Wind Energy Technologies Office. The Tethys team is supported by researchers at the National Renewable Energy Laboratory, Aquatera, and many other organizations that provide content and updates.

Website Development

Launched in 2011, Tethys is developed using Drupal, an open-source content management software, and draws on years of software and systems development expertise from the PNNL Development Team. Tethys aims to follow the FAIR (Findable, Accessible, Interoperable, Reusable) and FARR (FAIR, AI Readiness & Reproducibility) guiding principles. Tethys content is actively added and regularly reviewed, so it remains up to date and accurate. Feedback and suggestions from users are highly encouraged. 

Connection to PRIMRE Network

Tethys is one of seven knowledge hubs within the U.S. Portal and Repository for Information on Marine Renewable Energy (PRIMRE), which hosts additional marine energy data, information, and resources. Content from Tethys, Tethys Engineering, and other knowledge hubs are searchable in the centralized PRIMRE Search. Subscribe to the Tethys Blast and PRIMRE Blast newsletters to stay up to date.
