- Estimate the abundance of cetaceans in oceanic and shelf waters of the European Atlantic in 2016. - These estimates will give the necessary information to evaluate the good environmentla status and the conservation status of the main species of cetaceans in the Atlantic. - In addition these estimates are needed to evaluate the impact of the different anthropogenic pressures on the populations of these species.

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.

TAlPro-2016 represents the Western Mediterranean basin component of the MedSHIP initiative. The cruise will occupy two meridional sections, one across the relatively flat and deep Algero-Provencal basin, and one across the deep and rugged Tyrrhenian Sea. The data collected during these sections will allow to: 1) measure the changes in the thermohaline properties of Mediterranean water masses at the basin-scale; 2) quantify the Dissolved Inorganic Carbon (DIC) storage in the Western Mediterranean Sea; 3) quantify the uptake of anthropogenic carbon in the Western Mediterranean Sea; 4) quantify changes in the ventilation of the deep and intermediate water masses thanks to the transient tracers (CFCs and SF6).

The main objective of the Idrissi-2016 recovery cruise is to recovery the 10 Ocean Bottom Seismometers and Hydrophones (OBS/H) deployed in the ocean floor during the oceanographic mission Idrissi-2016 accomplished on September 2016. The OBS will have been acquiring earthquake data occurring in the area during 3 months under the sea. Seismic data will determine the shallow and deep crustal structure and plate geometry of the convergent system giving rise to earthquakes as the Mw 6.3 occurred on January 25th 2016, specially along the Al Idrissi fault, possibly the responsible of the geological hazards that threaten the region. In addition, the data acquired will allow improving our knowledge on the tectonics, faults parameters and landslides to define the most significant geological hazards, including large earthquakes and rarely tsunamis. Together with the OBS/H recovery, a detailed bathymetry survey of the Al Idrissi fault will be performed along the fault using hull-mounted echosounders on the vessel.

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 (fig. 1) and another perpendicular to the Guadalquivir River (Fig. 1) with a total of seven hydrographic stations for the study of the water column (Fig. 1) and two filling stations witnessed the sedimentary column in the River Guadalquivir transect (Fig. 1) .In addition be made physiography studies multibeam seabed probe. 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.
