The main objective of the project "VULcanología CAnaria submariNA, VULCANA", is assess the degree of damage and recovery on the marine ecosystem of the volcano submarine of the island of El Hierro, making it extensible to any other region sensitive to underwater volcanic activity in the archipelago. To do this, he held the monitoring of the physico-chemical, biological and geological properties of the submarine process of the island of El Hierro and other areas of volcanic interest, giving continuity to the first and only time series data of a multidisciplinary monogenetic submarine volcano in Spanish waters. 1 .- Study of the spatio-temporal variability of physical, chemical and biogeochemical. 2. Evaluation of the impact of the eruption process of trophic lower levels. 3. physiographic, morphological and structural characterization of the seabed associated emissions and adjacent offshore areas.

Main targets of PECAN 1602 are: - Setting-up of R/V Ángeles Alvariño as acoustic-fisheries prospecting vessel. - Optimizing sampling design for the systematic study and abundance estimating of Canary Islands pelagic species. - Using echo integration as a method to estimate Canary Islands pelagic species abundance.

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.

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).

Multidisciplinary cruise: Sampling physical and chemical variables that will: - Study thermohaline characteristics, kinematics, dynamics and biology of the eastern half of the Gulf of Cadiz - Study carbon fluxes between Atlantic and Mediterranean basins. - 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.

ISLAND is a research cruise that will address the above issues through the following 3 specific objectives: a) To explore how the NW Sicilian canyons evolved during the Late Quaternary (differences in style, frequencies and intensity of sedimentary flows, possible differences in forcing mechanisms) and to assess which canyon(s) is/are more “active” in the present-day conditions and why. b) To establish whether canyons displaying different morphologies and controlled by different processes may be characterized by differences in the spatial distribution and variability of benthic biomass and biodiversity (are the most active canyons always the most biodiverse?). c) To explore the role of bottom trawling fishery in shaping the morphology and governing the presentday dynamics of submarine canyons and eventually assess its impact in altering canyon biodiversity (is trawling activity affecting the natural canyon seascapes and sedimentary dynamics, inducing a change in biodiversity?).

The objective of the project RADIALES, formulated in 1990, aims at “understanding and modelling the response of the marine ecosystem to the sources of temporal variability in oceanographic and planktonic components, particularly foccusing in those factors and processes affecting biological production and potentially altering the ecosystem services”. This project represents the oldest multidisciplinary ocean observation initiative still active in Spain.
