This third investigation of the spillage of fuel in waters of Galicia and the Cantabrian Sea intended to continue the study of the impact of oil spills. In this edition, the monitoring of the process of recovery of ecosystems and exploited resources involved a study during spring flowering, period of higher production, to quantify the changes in the patterns of distribution and abundance of the communities. This campaign of 'evaluation of the impact of the Prestige discharges on the ecosystem of the platform and its fishing resources in spring time' was attended by researchers from the IEO, SGPM and CSIC. GOALS The general objective was to estimate the impact produced by the Prestige discharge on the demersal and benthic communities present on the continental shelf of Galicia, in soft bottoms between 35 and 500 meters. These communities are subject to considerable fishing exploitation and sustain the economy of numerous coastal towns of Galicia and the Cantabrian Sea. At the same time, geophysical studies were included, aimed at improving the knowledge of the funds of the internal platform, essential for carrying out sampling operations. The study was articulated around the following objectives: WORK AREA A multidisciplinary campaign of 16 days was proposed in the area of the platform between the Ría de Vigo and the mouth of the Bidasoa river. The study was conducted in affected areas of the continental shelf of Galicia and the Cantabrian Sea in funds between 35 and 500 m. To this end, a series of sampling stations arranged in radials and located in five geographical sectors and three depth layers (71-120, 121-200 and 201-500 m) were established, which corresponded to those of the historical series of survey campaigns. of the IEO (following figure). In areas of special interest due to the importance of the discharges, hauls were made at less than 70 m.
