Corrosion behaviour and biofouling characteristics of mild steel in three different coastal locations in the Gulf of Mannar,India have been studied over a period of 24 months. Oyster fouling was predominant at Open sea - Tuticorin, while barnacle fouling was dominant at both Mandapam and Harbour - Tuticorin. The rate of corrosion for 24 months exposure period was highest at Mandapam, where fouling was minimal. The surface of the mild steel was characterized by etchings & crevices beneath the hard foulers attached on it, at all the test locations. The depth of crevice caused by hard foulers was higher at Open sea - Tuticorin followed by Harbour - Tuticorin and Mandapam. The loss in ultimate tensile strength was more in Open sea - Tuticorin than the other two locations. Corrosion behaviour of mild steel is discussed based on the variation in the biofouling assemblage at the three test locations.
