Knowledge Base

The Knowledge Base provides access to information about the environmental effects of marine and wind energy, supporting OES-Environmental and WREN initiatives. Relevant documents and OES-Environmental metadata forms are compiled into a user-friendly table with advanced filtering. Filters may be selected on the right, or keywords entered in the Search Text box. Content may also be sorted alphabetically by clicking on column headers. More entries will load as you scroll down.


As an alternative to the Knowledge Base, check out the Map Viewer to access geotagged content in a spatial view.
