Abstract

Artificial structures such as wave and tidal energy devices provide surfaces and structures that are naturally colonised by marine flora and fauna. Properties of the building material, surface texture and structural complexity of the infrastructure will determine the suitability as a habitat for mar...

description Artificial structures such as wave and tidal energy devices provide surfaces and structures that are naturally colonised by marine flora and fauna. Properties of the building material, surface texture and structural complexity of the infrastructure will determine the suitability as a habitat for marine organisms.

Here we explore opportunities to not just tolerate the colonisation of marine infrastructure, but to design and manipulate features that would deliberately attract and host marine organisms.
