Zooplankton composition and distribution off the coast of Galicia, Spain

During June and September 1984, zooplankton samples were collected with other hydrographic and biological data along the Galician coast (NW of Spain). In June copepods contributed -60% to the total zooplankton community, with larvaceans, siphonophores and cladocerans also abundant. In September >...
