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.

Oceanographyc survey collected in the framework of theSTOCA and INGRES3 projects. STOCA is a program conducting systematic hydrographic and plankton observations along three standard sections in the eastern Gulf of Cadiz. INGRES3 is a Spanish Ministry for Science and innovation funded project that maintains a mooring line at the Spartel sill in the Strait of Gibraltar.

The main target of the "VULcanología CAnaria submariNA, VULCANA" project, is to study from a physicochemical, biological and geological point of view underwater volcanoes and hydrothermal systems active or not in the entire Canary basin. In addition, special attention will be given to the continuity of studies carried out in the Tagoro submarine volcano on the island of El Hierro, continuing like this, with one of the Longest physical-chemical-biological time series in the Spanish territory. The specific objectives of the Vulcana-III-0421 will be: 1.- Study of the temporal variability of physical, chemical and biogeochemical properties. a) Study of the temporal variability of temperature, salinity, pH-orp inside the crater the main submarine volcano Tagoro. b) Study of the spatio-temporal variability of thermohaline, fluorescence and oxygen fields dissolved in the hydrothermal plume of the Tagoro submarine volcano. c) Study of the spatio-temporal variability of the biogeochemical cycles of nutrients majority (nitrogen, phosphorus, silicon and ammonium). d) Evaluation of the anthropogenic influence through the analysis of marine microplastic in the water column 2.- Evaluation of the impact of the eruptive process on the microbial community. a) Study of the variability of the microbial community in relation to the emission of fluids hydrothermal by the Tagoro volcano. b) Study of the variability of microbial abundance in relation to the emission of fluids hydrothermal by the Tagoro volcano. c) Study of the variability of the chlorophyll concentration in relation to the emission of fluids hydrothermal by the Tagoro volcano. d) Study of the concentration and 12C / 13C isotopic ratio of CO2 and CH4 continuously dissolved in water surface and by discrete samples at different depths in the water column.
