The surveys on NAFO Regulatory Area of Div. 3L (Flemish Pass) were initiated by Spain in 2003. The surveys were carried out by the R/V 'Vizconde de Eza' following the same procedures and using the same bottom trawl net type Campelen.The main objectives of this survey time series are: a) to obtain abundance indices of the main exploited species, b) to study the structure and distribution of these demersal species in the area.

The survey in Div. 3NO of NAFO Regulatory Area was initiated by Spain in 1995. Until 2001, the survey was carried out in spring (May), on board the Spanish vessel C/V Playa de Menduiña (338 GT and 800 HP) using bottom trawl net type Pedreira. Since 2001, the R/V Vizconde de Eza replaced the C/V Playa de Menduiña as the research vessel for the survey, and Campelen net replaced Pedreira net as survey gear. The main objectives of this survey time series are: a) to obtain abundance indices of the main exploited species, b) to study the structure and distribution of these demersal species in the area.

Coinciding with the development of the project, Friday, April 2, 500 days have passed since a 26-year-old monocoque tanker, loaded with 77,000 tons of fuel, split in two. The Prestige sank 260 km from the Cies Islands, in the Vigo estuary, generating a first spot of 5,000 tons of fuel. This campaign analyzes the effects produced by the spillage of the Prestige hydrocarbon on the ecosystem of the continental shelf of Galicia. OBJECTIVES Multidisciplinary campaign that monitored the impact of oil spills on demersal and benthic communities in funds between 70 and 500 m. Likewise, the geophysical study of the worst known areas of the platform was undertaken, such as the rocky areas, which are, nevertheless, of great ecological and commercial importance, and possible areas of sedimentary deposit that can be points of accumulation and retention of fuel

From day 12 to day 31 of the month of April the B / O Vizconde de Eza made the first of a series of multidisciplinary campaigns aimed at improving knowledge of El Cachucho fishing ground, located on the Asturian marginal shelf within the Spanish EEZ. Morpho-sedimentary study of the "El Cachucho" fishing ground and adjacent area. Dynamics and characteristics of water bodies. Characterization of benthic and demersal communities.
