About Annex IV
Annex IV is a collaborative project among member nations of the IEA Ocean Energy Systems (OES) to examine environmental effects of ocean energy devices and projects. There is currently a wide range of ocean energy technologies and devices in development around the world; the few data that exist on environmental effects of these technologies are dispersed amongst different countries and developers.
Annex IV member countries collaborated to create a searchable, publically available database of research and monitoring information to evaluate environmental effects. The database includes data from ocean energy projects and research studies and case study reports compiled as part of this effort. Annex IV addresses wave, tidal and ocean current energy development, but not ocean thermal energy conversion (OTEC), energy derived from salinity gradients, or offshore wind. The construction of the database will coincided with the release of the Final Annex IV report with a worldwide focus on monitoring and mitigation methods including case study's from the database, the results of two experts' workshops, and lessons learned from the project.
The U.S. led the Annex IV effort; the Department of Energy (DOE) was the Operating Agent for Annex IV, working with federal partners the Federal Energy Regulatory Commission (FERC), the Bureau of Ocean Energy Management (BOEM), and the National Oceanic and Atmospheric Administration (NOAA).

Contributing to the Annex IV Effort
Metadata on MHK projects and research studies were gathered from countries around the world, using the Annex IV Project Sites Metadata Form and the Annex IV Research Studies Metadata Form. Technology developers, utilities, project developers, researchers and others are encouraged to submit data.
Use of Annex IV
The Tethys Knowledge Base page allows users to view, filter, and further explore all the existing Annex IV sites and associated documents. The Tethys map shows Annex IV activities from around the world and allows you to view information about International MHK development activities and research studies, as obtained from the Annex IV survey forms. Note that the Tethys Map and Knowledge Base contain both Tethys and Annex IV data. If you would like to ONLY view Annex IV entries, please click on Annex IV in the Collection facet box on the right had side of the screen.
