The objective of the project RADIALES, started in 1990, aims at “understanding and modelling the response of the marine ecosystem to the sources of temporal variability in oceanographic and planktonic components, focusing on those factors and processes affecting biological production and potentially altering the ecosystem services”. This project is the oldest multidisciplinary ocean observation initiative still active in Spain.

El objetivo de la campaña es conocer el estado de las poblaciones de las especies objetivo: su abundancia, biomasa y estructura demográfica, y las condiciones oceanográficas en el Banco. Este objetivo implica las siguientes acciones: • Prospectar el área de Flemish Cap, División 3M de NAFO hasta profundidades de 1460 m (800 brazas) mediante un muestreo aleatorio estratificado, haciendo 181 pescas válidas de arrastre con un arte Lofoten, diurnas: entre las 6.00 y las 22.00 horas, y una duración efectiva de arrastre de 30 minutos. • Realizar en cada pesca un muestreo biológico detallado de la captura para cada una de las especies objetivo, que incluya muestreos de talla, sexo, peso, otolitos y gónadas. Para las demás especies sólo se hará muestreo de tallas y muestreos talla-peso. • Análisis de los contenidos estomacales de las principales especies capturadas, a realizar cada dos años. • Identificación y registro de todas las especies de invertebrados presentes en las capturas. • Registrar las condiciones oceanográficas en el banco haciendo estaciones de CTD para cubrir un retículo con 15 millas de separación, tanto en longitud como en latitud.

Getting the spatial distribution and abundance indices of benthic and demersal fauna of the continental shelf of Galicia and Cantabrian Sea. Hydrographic survey of the neritic zone led to its influence on the distribution of species. Sampling using a box corer to obtain granulometrics indices of sediment.
