Abstract
THIS communication deals with some very distinctive formations originally noticed during routine investigations on seasonal fouling in the Menai Straits. The investigations were part of a project based on regular observations of the marine growths attaching to ‘Tufnol’ panels exposed for various time intervals from an anchored raft. Kite brand ‘Tufnol’, a paper based phenol-formaldehyde bonded material, is used in the investigation. The panels are exposed parallel to the direction of the main flow of current, which attains a velocity of 90 cm/sec on spring tides. The turbidity of the water varies from a Secchi disk extinction of 0.5 m to 5.0 m corresponding to 0.5 mg/l. to about 40 mg/1. ash weight of suspended material, the heaviest loads being carried in winter1.
