Succession (Fouling) Studies June, 2006			Pearson College –EnCana-- Clean Current Tidal Power Demonstration Project

					In the spring of 2005, a set of plates made up of 5 different materials and coatings was deployed in the centre of the main channel, straight out from the docks at Race Rocks at a depth of 12 metres. This is one set of the replicates, removed one year later on June 09, 2006.. Red filamentous algae growing on the aluminum surface at the base of the stand.
		Severe pitting and build up of white crusty mounds of Aluminum oxide on the stand. Early succession of Lithothamnion and other algaes Plastic bolts Stainles steel bolts
			Plate 1 Stainless Steel. After the year of submersion, both this stainless plate and the titanium plate have minimum fouling. Grazing by small snails and chitons is evident by tracks on the plates. Plate 2 Titanium Plate 3 Plate 4 ICI Coating Plate 5 Si Coat on the white side Plate 5 Interguard coating: Showing 1cm barnacle growing on base after coating is eroded. Interguard coating.
