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).

This campaign, financed entirely by the Spanish administration, is part of the agreement established between the SGPM and the IEORealization of research program in the fisheries as well as the research project funded by the General Secretariat of R & D of the Xunta de Galicia: Identification of commercial products from La Raya through DNA technology, developed in collaboration with the University of Vigo and the Technological Center of the Sea (CETMAR). Currently there is a moratorium on fishing for the commercial species of the Great Bank of Newfoundland, so the results of this campaign represent a valuable information for the Spanish administration. OBJECTIVES This campaign belongs to the series destined to obtain indices of abundance and to know the structure of the populations of commercial species in the area of Regulation of the NAFO, and in particular in the divisions 3N and 3O. WORK AREA Mainly worked in the queue of the Great Bank of Newfoundland outside the Exclusive Economic Zone of Canada, in divisions 3O and 3N of the area of regulation of NAFO.
