Tethys Environmental Impacts Knowledge Management System

The U.S. Department of Energy partnered with the International Energy Agency's Ocean Energy Systems initiative to create Tethys, a database and knowledge management system that provides access to information and research about the potential environmental effects of offshore wind and marine and hydrokinetic development.

Tethys also hosts data from Annex IV, an international collaboration to gather information on MHK environmental research worldwide.
