This survey covers the international NAFO Regulation Area in divisions 3NO. It started in 1995 with the only purpose of collecting data for stock assessment of target species down to 700 m, but its aims and research area have widened with time

In this cruise the mooring lines deployed in April 2012 have been recovered. In addition communication between acoustic receivers and a deck unit has been tested. This is part of the international program OTN ("Ocean Tracking Network," in Spanish "Red de Seguimiento Oceánico"). This work is preparatory for the deployment of a curtain listening across the Strait of Gibraltar.

Get abundance indices of groundfish demersales species. Get the size structure of commercially exploited stocks. Collection of biological material. Prospecting deep zones. Get physical-chemical parameters of water in the study area.

This survey main goal is to achieve the complete bathimetry of the designated area using multibeam echosounder EM710. After data procesing different DTM will be produced in order to characterize the area from a geomorphologic point of view. Sound velocity profiles will be carried out in order to obtain the best accuracy on the data adquired.

The cruise RadProf201209 is part of the timeseries program from the Spanish Institute of Oceanography (IEO) following international strategies for ocean climate monitoring (CLIVAR, GOOS etc). It covers a hydrographical section westwards of Cape Finisterre in Northwest Spain along the 43ºN latitude, extending c.a. 250 nm into the western Iberia basin. The sampling includes hydrography, current velocity fields and water samples collection for biogeopchemical analysis. It is planned the deployment of a mooring line at 43ºN; 11ºW, at a site where current measurements timeseries exist. RadProf201209 adds specific sampling of biogeochemical properties, organic matter and plankton in alliance with the research project BIOPROF.

The campaign targets under INFUECO 1112, to carry on board the research vessel Angeles Alvariño, are the identification and mapping of habitats and characterization of biogenic benthic and demersal species. Specific objectives focus on the investigation of benthic Banks areas of 'Amanay' and 'El Banquete' by direct and visual methods. Specifically: · Extensive visual videogrammetry HD with sled towed "APHIA 2012". · Study epibenthic fauna through the use of beam trawl, to capture sessile and reduced mobility fauna in shallow soft bottoms and rock, and rock dredge for qualitative sampling of wildlife sessile hard bottom fauna. · Recognition with multibeam bathymetric and TOPAS parametric probe.
