“The process of marine fouling upon submerged surfaces usually begins with the formation of a microorganismal biofilm ‘slime’ that has been shown to influence the subsequent development of macrofouling communities, including algae and invertebrates. This study seeks to understand the relationships between microbial components in slime communities that develop on man-made surfaces. The focus will be on biofilms formed on marine antifouling coatings as unlike natural surfaces, these materials have been chemically defined and are economically important.

Copper-based paint is the most commonly used antifouling strategy for the shipping industry, but in recent years there has been a move towards non-biocidal materials featuring a variety of foul-release and anti-fouling surface chemistries and microtopographies.  This project will observe the development of the early biofilm community upon these surfaces in both static and shear conditions, the effect of diatom Halamphora coffeaeformis on biofilm development, and the subsequent interaction between these biofilms and settlement of model fouling organisms – barnacle Amphibalanus amphitrite and tubeworm Spirobranchus kraussii  – with and without the presence of H. coffeaeformis.”
