Fitoplancton e condicoes oceanográficas em areas de ressurgencia do Perú (invierno de 1987 e 1988)

During winter periods in 1987 and 1988, corresponding to the Pós-Niño and "La Niña", respectively, 182 water samples were collected for phytoplankton qualitative and quantitative analysis. The samples were taken from perpendicular transects ot the coast of peru, between 4° and 12° S. The results were related to temperature, salinity, water density, inorganic nutrients (nitrate, silicate and phosphate), phytoplanskton biomass (Chl a) and peruvian anchovy (Engraulis ringens J.) date used to explain the results.
