This 144-page case study summarizes the 5-year experimental phase of the San Onofre Nuclear Generating Station’s artificial reef project whose overall goal is compensation for the loss of kelp bed resources impacted by the station’s operation. These include giant kelp, understory algae, invertebrates and fishes. The book includes a brief history of the mitigation project and components, details of its administration, and artificial reef design recommendations, based on the coauthors’ findings.
