To evaluate the structure of the phytoplankton community under upwelling and non-upwelling conditions in the Colombian central Caribbean coast and to establish its conditions, compared with similar oceanographic events on a regional scale, four samples, taken between July and September 2006, two in upwelling and two in nonupwelling condition, were carried out along the water column (0-50m) following the Eurelian method. Water samples with the Van Dorn bottle and horizontal tows were taken to determine phytoplankton composition, density, dominance and diversity. It was found that dia- toms were the dominant group, specifically species of the genera Skeletonema, Chaetoceros, Bacteriastrum and Thalassionema, showing densities higher than 50cel/L.  No clear differences were detected within the specific phytoplankton composition under both oceanographic conditions, but a higher cell density was evident for the non-upwelling one. From the ecological point of view, the phytoplankton is characterized by a high species richness, a low dominance and consequently by a high biodiversity. Thus, the phytoplankton community associated to the upwelling system of central Colombian Caribbean, emerges as an analog community to that found in the huge western permanent upwelling of the western border.
