Objective The INTRIGAS I cruise specifically aimed to: describe the population structures of benthic invertebrates and demersal fish for the main hydrological and sedimentary units in the Bay of Biscay (in terms of species present, abundance and biomass) and define the network of biotic interactions with and between these two populations. (Which are the structuring species? What are the resource species? What tropic types are predominant? Do prey species condition the type and abundance of their predators?). The INTRIGAS cruises fall under the Bay of Biscay study in the national coastal environment programme (PNEC), Benthic ecosystems project: natural and anthropogenic impacts, Strand 1 Dynamics and anthropogenic forcing on benthic populations of the Bay of Biscay: the case of the Grande Vasière mudflat. The cruise had 2 legs: 10-11 September and 11-13 October.
