Identification of benthic communities. During the cruise is intended to cover the following targets: - Identify the benthic habitats and their spatial distribution by direct sampling (epibentonic trawl) and indirect (ROV, sled). - Complete the floristic and faunistic inventory. - Characterize the sediment (grain size and organic matter). - Multibeam bathymetric survey. Further analysis of this information will give us to : - Perform a bionomic map of marine benthos, representing the bottom type and the biological community that inhabits it. - Estimate the benthic biodiversity. - Estimate the abundance of the most characteristic species. - Mapping the main habitats of interest. - Get a sedimentary map. - Complete the geomorphology of the study area.

The campaign targets under INFUECO 1112, to carry on board the research vessel Angeles Alvariño, are the identification and mapping of habitats and characterization of biogenic benthic and demersal species. Specific objectives focus on the investigation of benthic Banks areas of 'Amanay' and 'El Banquete' by direct and visual methods. Specifically: · Extensive visual videogrammetry HD with sled towed "APHIA 2012". · Study epibenthic fauna through the use of beam trawl, to capture sessile and reduced mobility fauna in shallow soft bottoms and rock, and rock dredge for qualitative sampling of wildlife sessile hard bottom fauna. · Recognition with multibeam bathymetric and TOPAS parametric probe.
