Spanish Porcupine bottom trawl survey aims to collect data on the distribution and relative abundance, and biological information of commercial fish in Porcupine bank area (ICES Division 7b-k). The primary target species are hake, monkfish, white anglerfish and megrim, which abundance indices are estimated by age, with abundance indices also estimated for Nephrops, four-spot megrim and blue whiting. Data collection is also collected for several other demersal fish species and invertebrates.

Get more information regarding the characteristics and distribution of benthic habitats present inside the Columbretes Islands Marine Reserve with the objective of Develop a bionomic map that covers the total extent. The complementary objective is the realization of the benthic cartography. It is intended to achieve location and subsequent georeferencing of the upwelling of gases present in the environment of the volcanic archipelago that forms The study area of ​​this campaign. Associated with this objective is intended to know the Bacterial community in the area of ​​gaseous upwellings and a physicochemical characterization of these areas.

Water masses distribution and effect of the upwelling system in the local ecosystem of the Canary Archipielago

To collect relevant information to evaluate The levels of eutrophication in the coastal strip between Algeciras and Barcelona (Iberian coast, Alborán Sea and NW Mediterranean).

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 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.

· 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.

Prácticas dirigidas a los alumnos de las asignaturas Ecología Acuática y Biología Marina de la UIB, con el objetivo de trabajar in situ las principales técnicas oceanográficas para la adquisición de información de la columna de agua y la obtención de muestras de agua y organismos del plancton y del bentos.

Main targets: · ESTOC Observatory service - FixO3. · ESTOC time-series - Winter sampling. · Coastal observatory sampling. · Time Serie for environmental control of the PLOCAN test bed.

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.
