The effect of the "Prestige" oil spill on the plankton of the N-NW Spanish coast
15 páginas, 3 tablas, 8 figuras.-- Manuel Varela . et al. Chlorophyll, primary production, zooplankton biomass and the species composition of phytoplankton and zooplankton were studied in 2003, after the Prestige shipwreck. The information obtained was compared to previous data series available for...
