Abstract
Fouling organisms were collected from a platform by divers while it was in position and subsequently by the author after the platform was removed and brought ashore. Techniques used included light and scanning electron microscopy and X-ray analysis (EDAX). Although relatively few species of algae [Amphora, Biddulphia, Coscinodiscus, Navicula and Rhaphoneis] were involved, results indicated that these might have significant effects.
