The Knowledge Base provides access to information about technical and engineering aspects of marine energy. Relevant documents from around the world are compiled into a user-friendly table that displays all content available in Tethys Engineering. Results can be narrowed using the keyword filters on the right, or with search terms entered in the text box, including targeted searches (e.g., org:DOE, author:polagye). Content may also be sorted alphabetically by clicking on column headers. Some entries will appear on the next page.
As an alternative to the Knowledge Base, check out the Map Viewer to access geotagged content in a spatial view.
