Annually, the European Union develops two research campaigns in the area of NAFO (North Atlantic Fisheries Organization), one in the 3NO division and another in the 3M and 3L (Flemish Cap Series). This campaign is part of a historical series in order to provide indices for the evaluation of the stock of halibut and other groundfish species in the area such as flounder, redfish, grenadier, cod or shrimp. The Flemish Cap bank is an isolated bank of the American coastal platform with an area greater than 10,000 square miles and is located outside of the Exclusive Economic Zone of Canada. The exploitation of the resources of this area is regulated by the international agreements of NAFO. GOALS Estimation of abundance and biomass indices of the target species, as well as the study and analysis of the demographic structure of their populations and the oceanographic conditions in the Bank.

The oceanographic vessel Vizconde de Eza developed its first research campaign in Galicia as a result of the unfortunate accident and sinking of the Prestige oil tanker. In January of 2003, this project was undertaken to estimate the impact produced by the discharge of hydrocarbon on the demersal communities on the continental shelf of Galicia, in soft bottoms between 90 and 500 m, testing new acoustic methods for the detection of fuel the depths fixed. This multidisciplinary campaign took place over eight days on board the B / O Vizconde de Eza in the area of the continental shelf between the Ría de Muros and La Coruña. The study of the main members of the bottom communities (infauna, epifauna, suprabenths and benthic and demersal macrofauna) was included, for which 20 sampling stations were established located in the three strata of the standardized trawl campaigns (70 - 120, 121 - 200 and 201 - 500 meters).
