Cal Poly focused on biological assessments of nontoxic, foul-release and anti-fouling coatings to expedite the down-select process of new coatings. We utilized a suite of field tests to assess the performance of coatings provided to us from collaborators within the coatings testing program . Additionally, we participated in the intersite calibration study and collected ocean water quality parameters to be used to better characterize the biofouling community in relation to coatings and their performance. During the last grant period we tested 37 coating formulations and provided 16 technical reports about the performance of these coatings. Our water quality station has been functional for nearly the entire grant cycle. We are working to test the relationships between the recruitment of fouling organisms to intersite panels and water quality parameters. The static immersion site operated by Cal Poly provides a unique temperate marine environment for the testing of novel coatings within the coatings testing program.
