Aluminum anodes operating in seawater environments may become biofouled. This paper presents results of field studies that measured the change in performance of Al-Zn-Hg sacrificial anodes with respect to cover by marine growths. Electrochemical data showed that encrusting growths on anode surface increased resistance values and reduced anode current output. Loss of anode performance was greater on nonworking than working anodes. Biofouled nonworking anodes will become active and were capable of providing cathodic protection (CP) when connected to a steel cathode but a current densities below theoretical values.
