Zona costera, diatomeas, dinoflagelados, cianobacterias, hidrografía. Zona costeira, diatomáceas, dinoflagelados, cianobactérias, hidrografia. In order to study the phytoplankton structure in the gulf of Papagayo, 2 sampling cruises were conducted in February and June of 2017, and hydrographic information was additionally analyzed. The phytoplankton composition was dominated in both months by diatoms, dinoflagellates, cyanobacteria and flagellates. The fraction of diatoms contributed mainly to the phytoplankton structure with 41 taxa, followed by dinoflagellates with 20 taxa. In diatoms, the genera with the greatest contribution to diversity and frequency were Rhizosolenia sp., Guinardia sp., and Thalassiosira sp. In the case of dinoflagellates, Tripos furca predominated in station 20 located in Culebra Bay, while Gyrodiniumspirale was frequent, as well as genera Gymnodinium sp., Gyrodinium sp., and Amphidinium sp. Cyanobacteria were mainly composed by genera Analysis sp. and Chroococcus sp. and haptoficeas and flagellates, by the Coccolitoforids and the genus Chrysocromulina sp., respectively. In February the phytoplankton concentration varied between 326 and 1063 cells mL-1, and in June between 653 and 1041 cells mL-1, with mesotrophic characteristics in both seasons. The gulf’s hydrography is regulated by the annual rainfall cycle and the seasonal coastal upwelling of Papagayo. In February, as opposed to October, surface temperature decreased by 3°C, salinity increased by 2 and chlorophyll-a concentration increased by 0.5 mg .m-3. Warmer waters, with lower saline and chlorophyll-a concentrations in October (T > 29°, S < 32.2, Chl-a < 0.5 mg m-3) are opposed to February results. Con el propósito de estudiar la estructura de la comunidad fitoplanctónica en el golfo de Papagayo, se realizaron 2 muestreos en febrero y junio del 2017, y se analizó adicionalmente información hidrográfica. Su composición estuvo dominada, en ambas épocas, por diatomeas, dinoflagelados, cianobacterias y flagelados. La fracción de diatomeas aportó mayoritariamente a la estructura del fitoplancton con 41 taxa, luego los dinoflagelados con 20. En las diatomeas, los géneros más abundantes y con mayor frecuencia de aparición fueron Rhizosolenia sp., Guinardia sp. y Thalassiosira sp. En los dinoflagelados, Tripos furca predominó en la estación 20 en Bahía Culebra y resultó frecuente Gyrodiniumspirale, así como y los géneros Gymnodinium sp., Gyrodinium sp. y Amphidinium sp. Las cianobacterias estuvieron representadas, principalmente, por formas chroocoides de los géneros Anacystis sp. y Chroococcus sp., al igual que las haptoficeas y los flagelados, por los coccolitoforidos y el género Chrysocromulina sp., respectivamente. En febrero, la concentración fitoplanctónica varió entre 326 y 1063 cél mL-1, y en junio entre 653 y 1041 cél mL-1, con características mesotróficas en ambas épocas. La hidrografía estuvo regulada por el ciclo anual de precipitaciones y el afloramiento estacional costero de Papagayo. En febrero, respecto a octubre, la temperatura superficial descendió 3°C, la salinidad ascendió 2 y la concentración de clorofila-a aumentó en 0.5 mg .m-3. Aguas más cálidas, menos salinas y con menores concentraciones de clorofila-a en octubre (T > 29 °C, S < 32.2, Chl-a < 0.5 mg m-3) contrastan con lo observado en febrero. A fim de estudar a estrutura da comunidade fitoplanctônica no Golfo de Papagayo, foram realizadas 2 amostragens em fevereiro e junho de 2017, e as informações hidrográficas foram adicionalmente analisadas. Sua composição foi dominada, em ambos os períodos, por diatomáceas, dinoflagelados, cianobactérias e flagelados. A fração de diatomáceas contribui principalmente para a estrutura de fitoplâncton com 41 táxons, em seguida, os dinoflagelados com 20. Nas diatomáceas, os géneros mais abundantes, e que apareceram com mais frequência, foram os Rhizosolenia sp., Guinardia sp. e Thalassiosira sp. Nos dinoflagelados, os Tripos furca predominaram na estação 20 na Baía Culebra e resultou ser frequente o Gyrodiniumspirale, como também os gêneros Gymnodinium sp., Gyrodinium sp. e Amphidinium sp. As cianobactérias foram representadas, principalmente, pelas formas cocóides do gênero Anacystis sp. e Chroococcus sp., bem como pelas haptoficeas e flagelados, pelos cocolitoforídeos e pelo gênero Chrysocromulina sp., respectivamente. Em fevereiro, a concentração de fitoplâncton variou entre 326 e 1063 células mL-1 e, em junho, entre 653 e 1041 células mL-1, com características mesotróficas nas duas épocas. A hidrografia foi regulada pelo ciclo anual de chuvas e pelo afloramento costeiro sazonal de Papagayo. Em fevereiro, em relação a outubro, a temperatura da superfície diminuiu 3 ° C, a salinidade aumentou 2 e a concentração de clorofila-a aumentou 0,5 mg / m3. Águas mais quente, menos solução salina e com concentrações mais baixas de clorofila- a em outubro (T> 29 ° C, S <32,2, Chl- a <0,5 mg de m-3) contrastam com o observado em fevereiro.
