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. ¿ 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.

· Ampliación de la formación de los técnicos, en especial en el uso de rosetas/CTD, SBL y sondas. · Familiarización de los técnicos con el buque Ángeles Alvariño y su equipamiento. · Comprobar el funcionamiento de los equipos electrónicos/informáticos del buque. · Realización de los ejercicios de seguridad mensuales, incluyendo nocturnos, que se intercalarán entre las pruebas de equipos.

The main objective is to characterize the water masses in the region from the surface to 5000m. This transect is part of a serie of hidrographic cruises that since 2003 are developed as part of the core program of the IEO.

The main objective is that students of MIOUCA become familiar with some of the techniques that can be used aboard a research vessel. To do this, aboard the "B / O Angeles Alvariño" of the Spanish Institute of Oceanography (IEO), students will perform a series of activities that will enable the characterization of the water column and seabed, from a point of view multidisciplinary and integrative (biological, physical, chemical and geological), along two radial one perpendicular to the Cape Trafalgar and another perpendicular to the Guadalquivir River. To obtain the information necessary to perform this study different sampling techniques will be used, and data acquisition and analysis, and ship with their own computers. In this way the campaign will contribute to a comprehensive education of students in the multidisciplinary study of an oceanic region, with the participation of teachers in different areas of knowledge.

Recent geomorphological studies in the Alboran Sea using multibeam data and seismic profiles have revealed the presence of 4 fields of mounds, probably formed by ecosystem-engineering species, in the upper slope of the Spanish Margin, close to the shelf edge. These fields are located between 160 and 320 m depth, in a sedimentary context that belongs to a contouritic terrace, previously defined by Ercilla et al. (2016) in the upper slope of the northen Alboran sea. This terrace is formed by turbulent processes associated with the interface of the Surficial Atlantic water and the Mediterranean Intermediate water masses, as well as with their oscillation during quaternary glacial and interglacial periods. These mounds are located at the proximal side of the terraces, close to the shelf break, and are exposed to the Western Intermediate Water and Modified Atlantic water masses based on previous studies using CTD data. The main aim of this project is to characterize the habitats and associated biota, focusing especially on the dominant habitat-forming species of these mounds, as well as to define the geological and oceanographic factors that may modulate their development.
