    Multidisciplinary cruise: Mooring,sampling physical and chemical variables that will: - Study thermohaline characteristics, kinematics, dynamics and biology of the eastern half of the Gulf of Cadiz - Study of carbon flows between the Atlantic and Mediterranean watershed. - Establish relationships between climate, hydrology and hydrodynamics and the early stages of development of the species associated with the platform, with emphasis on species of commercial interest in a space/time. - Provide data to feed global and regional numerical models. - Generate and distribute a database for the evolution of the marine climate and its resources.

    The marine ecosystem of the island of El Hierro, one of the richest and most sensitive of the spanish region, is experiencing the consequences of the first recorded underwater eruption in the Canary Islands in the last 500 years of volcanological history. The principal objective of VULCANO is to characterize the marine ecosystem from a physical-chemical-biological approach in order to quantify the environmental impact caused by the eruptive process. This main aim splits into five particular objectives: 1) to characterize the ecosystem before and after the eruption process, 2) to study the spatio-temporal variability of physical, chemical and biogeochemical properties, 3) to evaluate the impact of the eruptive process on lower trophic levels and 4) Characterization of the physiographic, morphological and structural changes on the seafloor associeted to submarine eruptions and 5) the data integration in existing databases, SIG implementation and dissemination by viewers. These objectives will be accomplished through the development of a multidisciplinary working plan which includes the realization of 3 oceanographic cruises and satellite observations.

    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, mass transport, heat and nutrients and interannual variability. • Characterize the different modes of variability of heat and mass transport in easternorth atlantic subtropical gyre. • To determine the correlation between heat and mass transport with the NAO atmospheric and oceanic index. • 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) and bottom waters of the Canary Basin, in based on temperature, salinity, nutrients and oxygen. • Characterize the zooplankton in the waters of the Canary archipelago, including biomass, abundances and taxonomy, as well as its metabolism: respiration, growth, excretion, ingestion, etc.

    Pelagic trawl estimation and acoustic methods of the biomass index and population and biological parameters of anchovy (Engraulis encrasilocus) and sardine (Sardina pilchardus) as a secondary objective to assess the state of fisheries. In pelagic trawling, the Daily Egg Production Method (MPDH) is applied as an estimate of biomass. Study of the influence of the variables of the water column (temperature, salinity and chlorophyll).
