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.

In January 2012, a physical-geological mooring was installed to the East of Elephant Island onboard the RV Hesperides. The mooring was constituted by current meters, temperature, conductivity, and pressure sensors located at selected depths. The mooring was deployed for one year period, and successfully recovered on January 23rd 2013 during the Hesperides Antarctic Survey 2012-2013. The goal of the experiment is to monitor the presence / absence of the Antarctic slope front over the southern slope of the South Scotia Ridge. The addition of a sediment trap will allow to identify the terrigenous / biogenic composition of the flow suspended particles. In an international context, the collected data will be used to optimize the MITgcm Antarctic regional model (ECCO2/ECCO3 project, JPL/Caltech).
