3. Characterization of the benthic and demersal communities
The analyses of the communities that inhabit the study areas are undertaken according to the information provided by the geophysical studies, and are mainly directed to benthic megafauna and demersal fish. In the first case we include the study of the three principal compartments of the benthic domain: the endobenthic communities of sediment bottoms and the epibenthic and suprabenthic communities, both of soft and rocky bottoms. This study will be based in the systematic determination of taxa accessible with different sampling methods and at common stations, and the joint quantitative analysis of abundance and biomass together with abiotic factors from the water column and the sediment. The integrated data treatment will allow us to obtain an overview of biodiversity of the benthic ecosystem and determine the putative environmental factors responsible for the distribution and structuring of the different community types.
