Although the biofouling process contributes to the productivity of coastal waters, it also leads to the unwanted accumulation of organic material on submerged surfaces that perform better or last longer when kept clean. In the past, toxic coatings were applied, but their potent indiscriminate attack on live organisms meant that many bystanders were adversely affected, mostly algae and animals living in the water or on the seafloor in harbors. The development of efficacious but environmentally friendly coatings requires a strong understanding of the biofouling process at different time scales, and adequate testing of experimental surfaces that takes into account the targeted organisms, the structures to be outfitted, and exposure to relevant environmental conditions. Current efforts in my research program aim to document the adhesion steps of micro- and macro-fouling communities. The program not only addresses the identification of organisms with traditional microscopes, it also includes the use of a molecular fingerprinting technique to differentiate microbial communities very early in the biofilm formation. This allows for the rapid screening of coatings or materials for their potential anti-fouling properties by comparison with untreated surfaces.
