RADIAL FLOW CHAMBER

The Radial Flow Chamber was used to determine the attachment strengths of four marine diatoms common on the hulls of in-service shipping. The influence of incubation times (1 to 96 h) and surface roughness (smooth and two grades of surface roughness) on the attachment strength of the diatoms was investigated. The diatoms showed marked variation in their relative strength of adhesion. For all diatoms there was an increase in attachment strength with incubation time, although marked differences were observed in the rate of increase. By providing protection from fluid flow, the two roughened surfaces increased the attachment strength of all diatoms throughout the incubation period. There appeared, therefore, to be a direct relationship between the morphology and adhesive strength of the diatoms. These results appeared to correlate well with the abundance and observed distribution pattern recorded for these genera on in-service shipping.
