21. BIOFiltration & AQuaculture: an evaluation of hard substrate deployment performance with mariculture developments

1. To quantify the effectiveness of the biofilters in reducing the impacts of mariculture across Europe from both an economic and environmental perspective. 2. To determine the best design and placements of the biofilters, accounting for differences in geography, hydrology, nutrient input etc. between countries. 3. To examine the environmental and regulatory options governing the use of the biofilters at the end of their life-span and to provide detailed economic analyses of biofilter use compared to existing filtration methods.

22. Marine artificial habitat manipulation: predicition and measurement of environmental impacts

1. To establish an environmental monitoring regieme during and following the period of reef complex construction using, where possible, the same static monitoring sites and transects established during the pre-deployment research, in addition to new stations 2. To develop and test models that will predict ecosystem changes caused by artifical habitat manipulation. The main model will examine whole ecosystem changes. Other models will examine hydrological profile alterations, habitat fractal dimensions and socio-economic cost benefit analysis.

23. Diversity and function of the bacterial flora of the toxic alga Gymnodinium catenatum Graham

1. To descirbe and compare the phylogenetic diversity and distribution of the total bacterial flora associated with G catenatum cysts and vegetative cells. 2. To culture and identify bacteria from G catenatum, and identify/characterise any bacteria capable of autonomous PST production in G. catenatum 3. To examine the effect of cyst surface sterilisation and re-introduction of bacteria on PST production in G catenatum 4. Survey bacteria for quorum sensing capability (cell signaling) and detect in situ quorum sesing in xenic G. catenatum cultures, relating to toxicity development. 5. Develop molecular markers of cross species quorum sensing, facilitating analysis of quorum sensing in uncultivated bacteria.

25. Atlantic Coral Ecosystem Study (ACES)

Objective 1: To map the structural and genetic variability, the framework-constructing potential, and the longevity of Deep Water Coral (DWC) ecosystems Objective 2: To assess hydrographic and other local physical forcing factors affecting Benthic Boundary Layer (BBL) sediment particle dynamics and POC supply in the vicinity of DWC ecosystems Objective 3: To describe the DWC ecosystem, its dynamics and functioning; investigate coral biology and behaviour and assess coral sensitivity to natural and anthropogenic stressors Objective 4: To assign a sensitivity code, identify the major conservation issues (and increase public awareness), and make recommendations for the sustainable use of the DWC ecosystem
