The goals of this survey are framed within the educational activity of the Faculty of Marine Sciences ULPGC to give the possibility of a complete oceanographic study (Physical , Chemical , Biological and Geological Survey ) in the south of Gran Canaria students of Degree, Bachelor and Master , the convergence zone between the area and the trail of the island and the presence of permanent rotation south of it. Thus this survey will contribute to a comprehensive training for students in oceanographic study of an oceanic region may  Determine the structure of water bodies, the effects of convergence and divergence to the passage of the Canary Current across the channels between islands, mass transport , and nutrients.  Determine the distribution of chemical species , including oxygen and carbon dioxide system and quantify the transport of CO2 in the atmosphere-ocean study area , the effect of micro and mesoscale phenomena in their distribution.  To characterize the effect of the wake , turns and other mesoscale structures in the distribution of species of phytoplankton and zooplankton.

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.

The EU funded MIDAS RTD project (7th FP, gran agreement 603418) overarching objective is to determine the impact of deep-sea mining on deep marine ecosystems. The eruption of the submarine volcano of El Hierro in 2011_12 and its impacts on the ecosystem are, in some aspects, a possible analog of deep ocean mining. The was focused on the research of the effects on the seabed and benthic and pelagic ecosystems of nepheloid layers and acidic waters resulting from the eruption. Inspection tasks has been carried out and, when possible, sampling of rocks, sediments and water by the ROV "Liropus 2000. Sampling of surface sediments through multicore, box-corer and Van Veen grab, and profiling and sampling of the water column, especially near the bottom, using CTD with rosette. The areas studied are the slope where the eruption and sectors more or less close with varying degrees of involvement took place, including sectors not affected in both flanks of El Hierro. Work out bathymetric mapping and seismic profiling also are been made.

The campaign targets under TASIFE 0414, to carry on board the research vessel Angeles Alvariño, are the set up and maintenance of equipment deep underwater photography TASIFE 2013. Specific objectives focus on the investigation of benthic Banks areas of 'Reserva Marina de La Palma' and 'ZEC Franja Marina Teno-Rasca (Tenerife)' by direct and visual methods. Specifically: · Extensive visual videogrammetry HD with sled towed "NEXUS". · Recognition with multibeam bathymetric probe.

Oceanographic survey collected in the framework of the following research project: ¿Métodos de Producción de Huevos. Estimación de la biomasa de especies pelágicas de interés comercial: sardina, anchoa, caballa y jurel (ICTIOEVA)¿. This Project is funded by the Instituto Español de Oceanografía and the main scientific objective the survey is to produce an index and a direct estimate of the spawning stock biomass of Sardine (Sardine pilchardus) in the Cantabrian Sea and Bay of Biscay (to 45ºN) using the Daily Egg Production Method (DEPM). Specific aims:a) To estimate the spawning area distribution of sardine and the daily egg production. b) To collect adults to obtain fecundity estimation c) Distribution and abundance of other commercial species of interest: mackerel, horse mackerel and anchovy.d) To describe the oceanographic and meteorological character of the area of study with the aim of relating environmental conditions (temperature, salinity, currents) with the spatial distribution of the ichthyoplankton

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.
