    Algunas características del florecimiento del fitoplancton en el frente del Río de la Plata. I. Los sistemas nutritivos
    (Mar del Plata: Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP), 1986) Negri, R.M.; Carreto, J.I.; Benavides, H.R.
    During the spring (H-04/82: october 11-27, 1982) carried out by the Fishery Research Vessel "Dr.E.Holmberg", the distribution of temperature, salinity, nutrients concentration and photosynthetic pigments were studied at the "Rio de la Plata" maritime front. The presence of Sub-Tropical coastal waters in only station did not allow its characterization. Low Chlorophyll a concentration were noted, in association with scarce concentrations of nutrients and high Margalef index values.
