Abstract
As a member of research team of the Hawaii National Marine Renewable Energy Center, the author of this report (Dr. Guangyi Wang, Department of Oceanography) collaborated with Dr. Lloyd Hihara (Hawaii Corrosion Laboratory, Department of Mechanical Engineering) to work on the center's project topic "increased reliability and survivability of marine and hydrokinetic renewable energy technologies, including development of corrosive-resistant materials". This report summarizes test results of antifouling coating and antifouling activity screening of natural compounds derived from marine algae and sponges.
