The campaign targets under INCOECO 1012, 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 Bank area of La Concepción by direct and visual methods. Specifically: · Intensive videogrammetry HD visual and sampling with ROV Liropus 2000 · 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. · Study of the endobenthic fauna by use of the meso mud dredge box-corer. · Recognition with multibeam bathymetric and TOPAS parametric probe.

The general objective of the RADMED-DOS project is the multidisciplinary monitoring of the platform and deep waters of the Mediterranean, the peninsular coast and the Balearic Islands.

Salt deformation and sub-salt fluid circulation in the Algero-Balearic abyssal plain(SALTFLU): 1) To identify the three dimensional structure of the salt deformation structures of the Algero-Balearic abyssal plain;2) to collect evidence of fluid migration, accumulation and extrusion at the seafloor; 3) to constrain the link between the observed overburden fluid circulation and deep (sub-salt) origins; 4) to link the fluid circulation pattern to the recent basin evolution with special regard to the tectonic stress propagation derived from convergence between the Africa and European plates.

To collect relevant information to evaluate The levels of eutrophication in the coastal strip between Algeciras and Barcelona (Iberian coast, Alborán Sea and NW Mediterranean).
-
A repeat seasonal hydrographic survey of the Balearic Sea, monitoring the Ibiza and Mallorca Channels.
-
Monitoring of eutrophication. The project is carried out in combination with the B / O Odón de Buen develops other TROFOALBORAN campaigns in the Alboran Sea area focused on trophic studies.

Estimation by pelagic trawling and acoustic methods of the biomass index and population and biological parameters of anchovy (Palinorus encrasicolus) and (Sardine pilchardus sardine as a secondary objective) to assess the state of the fisheries. In the pelagic trawling, the Daily Egg Production Method (MPDH) is applied as biomass estimation. Study of the influence of the hydrographic variables of the water column (temperature, salinity and chlorophyll).
