In spite of the high nutrient supply, phytoplankton growth was limited by a reduced light penetration related to concentrations of suspended particles.El fitoplancton fue estudiado mensualmente desde junio 1995 a mayo 1996, en 16 estaciones que reciben diferentes descargas, en el sector oriental del Golfo de Cariaco. Sólo la clorofila, las abundancias de diatomeas, dinoflagelados y totales sufrieron un efecto diferencial con la profundidad. La salinidad y el oxígeno sufrieron diferenciación con la ubicación de las estaciones. Los máximos de fitoplancton de noviembre-diciembre, se relacionaron con bajos niveles de nutrientes nitrogenados y temperatura, elevados niveles de fosfato, clorofila y oxígeno disuelto. De junio a octubre predominaron temperaturas cálidas, bajas concentraciones· de nutIientes; oxígeno y abundancia del fitoplancton. En general la abundancia del fitoplancton fue baja. Las diatomeas dominaron durante el período analizado, pero los micro flagelados y dinoflagelados lo hicieron ocasionalmente. Los máximos de fitoplancton presentaron relación con los incrementos de fósforo y desfases con los máximos de nitrógeno. A pesar del elevado aporte de nutrientes, el crecimiento del fitoplancton fue limitado debido a la gran cantidad de partículas en suspensión, que reducen la penetración de luz.Universidad de Costa Rica1999-03-01info:eu-repo/semantics/publishedVersionArticleartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdfhttps://revistas.ucr.ac.cr/index.php/rbt/article/view/26141Revista de Biología Tropical; Vol. 47 No. S1 (1999): Volume 47 – Supplement 1 – March 1999: Latinamerican Planctology; 57–63Revista de Biología Tropical; Vol. 47 Núm.

Phytoplankton was sampled monthly during the lune 1995-May 1996 period, at 16 stations of the eastern Gulf of Cariaco. This area receives different wastes. Only chlorophyll and diatoms, dinoflagellates, and total density of phytoplankton varied by depth. Only salinity and oxygen showed horizontal spatial differcl1tiation. Phytoplunkton maxima in November- December, were related with low nitrogenous nutrients and temperature, high phosphate, chlorophyll, and dissolved oxygen. The June-October period was characterized by high temperature, low oxygen, nutrient concentrations and phytoplankton abundance. Overall, phytoplankton abundances were low. Diatoms dominated during the sampling period, but microflagellates and dinoflagelates did occasionally. Phytoplankton density was positively correlated with phosphate and negatively with nitrogen.
