Test panels were held in racks
and hung on AR20
in January 1999. They were retrieved quarterly and the
last one was retrieved in January 2001. Fouling organisms on the
were examined and compared.
1. Season and length of submersion had strong
influence on the totalbiomassand community structure.
2. Type of substratum had very little impact on the total biomass or
structure and of benthiccommunity.
3. Season of submersion determined species composition of newly submerged
surfaces. In spring and summer, tubeworms
were the most abundant. In autumn and winter, barnacles
4. Community succession was not obvious in the first year of submersion
as it was intermingled with strong seasonal settlement, growth and death
5. In the second year of submersion, green
mussels and tunicates
settled and grew to occupy most of the panel surface, forming an
assemblage characteristic of climax communities in local subtidal
