The goals of this campaign are framed within the objectives of the overall project 'Radial Profunda de Canarias', being the experimental cruise of the proposal. Thus, this cruise will help to: • Determine the structure of the current when it reaches the Canary Islands, of the Outcrop Current and the polar counterflow of slope in its passage through the Canary Archipelago and the African slope, stimating its mass transport, heat and nutrients. • Characterize the different modes of variability of heat and mass transport in easternorth atlantic subtropical gyre and the oucrop in northwest African coast. • Characterize the annual cycle in the physical conditions of the surface layers and mixture to where the seasonal cycle is significant, relating it to the meteorological forcings. • Characterization of changes in water masses, mainly in the North Atlantic Central Water (NACW), in Antarctic Atlantic Intermediate Water (AAIW) in Mediterranean Water (MW), bottom waters of the Canary Basin and the oucrop in northwest African coast, in based on temperature, salinity, nutrients and oxygen. • To characterize the zooplancton and micronecton deep communities. • To charactereze the microbian and heterotrophic communities.

Getting the spatial distribution and abundance indices of benthic and demersal fauna of the continental shelf of Galicia and Cantabrian Sea. Hydrographic survey of the neritic zone led to its influence on the distribution of species. Sampling using a box corer to obtain granulometrics indices of sediment.
-
Study of strategies to reduce discards and unwanted species: selectivity and survival in trawling in Cantabrian-Northwest zone.
-
Acoustic evaluation and mapping of neritic pelagic resources and oceanographic and biological conditions of the continental shelf of the Gulf of Cadiz.
-
Estimating the abundance and population structure of the target species of the trawl fishery in the Mediterranean, identified in the MEDITS project (Annex I), studying the biology of exploited communities on the shelf and upper slope of the study area and the impact of fishing on ecosystems.
-
Estimation by acoustical methods stock biomass of anchovy (Engraulis encrasicolus) and sardine (Sardina pilchardus) Spanish Mediterranean.

Estimating the abundance and population structure of the target species of the trawl fishery in the Mediterranean, identified in the MEDITS project (Annex I), studying the biology of exploited communities on the shelf and upper slope of the study area and the impact of fishing on ecosystems.
-
Get abundance indices of groundfish demersales species. Get the size structure of commercially exploited stocks. Collection of biological material. Prospecting deep zones. Get physical-chemical parameters of water in the study area.
