The Ría of Vigo (Galicia, NW Spain) is an estuary located in the northern boundary (42–43°N) of the eastern North Atlantic upwelling system. Since 1994, the Instituto Español de Oceanografía (IEO), as part of RADIALES program, has been monitoring, in a monthly basis, a hydrographic standard section composed of 4 oceanographic stations located in the inner, medium and outer part of the ría. In addition to hydrographic profiles, biogeochemical and plankton samples have been collected. The average values of the main nutrients in the study area and its inter- and intra-annual variability in relation with the oceanographic features are represented in order to establish reference and range values for the different seasons.
