Annual variation of phytoplankton productivity in Estero de Punta Banda, B.C.

Annual variation of phytoplankton productivity in Estero de Punta Banda, B.C.

Eleven time series were carried out at one station in Estero de Punta Banda, from June 1987 to May 1988. The samples were taken during the day at spring and neap tides and the following variables were analysed: temperature, salinity, concentration of phosphates, nitrates, silicates and chlorophyll a...

Variación anual de la productividad del fitoplancton en el Estero de Punta Banda, B.C. Muñoz-Anderson, MA Millán-Núñez, R Eleven time series were carried out at one station in Estero de Punta Banda, from June 1987 to May 1988. The samples were taken during the day at spring and neap tides and the following variables were analysed: temperature, salinity, concentration of phosphates, nitrates, silicates and chlorophyll a. Two primary productivity experiments were conducted with the carbon-fourteen method for each sampling. The maximum temperature, 22.16ºC, occurred in summer and the minimum, 16.33ºC, in winter. Both the amplitude of variation and the chlorophyll a concentration were higher in summer. The average of the concentration of nitrates and phosphates of each sampling was very similar throughout the year, except in January due to a storm that caused mixing and homogenization in the water column of the bay, causing the concentration to increase during the flow of the tidal current in the Estero. Primary productivity was higher during the summer months, reaching values of up to 68.32 mgC/ms/h, and lower in autumn and winter with values of 3.57 mgC/m3/h. High assimilation ratio values are reported during neap tides.  Se realizaron 11 series de tiempo en una estación del estero de Punta Banda, de junio de 1987 a mayo de 1988. Se muestreó en el día en mareas vivas y muertas, analizando las siguientes variables: temperatura, salinidad, concentración de fosfatos, nitratos, silicatos y clorofila a. Se realizaron dos experimentos de productividad primaria con el método de carbono catorce en cada muestreo. La temperatura presentó sus valores máximos en verano con 22.16º y un mínimo en invierno de 16.33ºC. Tanto la amplitud de variación como la concentración de clorofila a fue mayor en verano. El promedio de la concentración de los nitratos y fosfatos de cada muestreo fue muy similar durante todo el año, excepto en enero debido a la tormenta que provocó mezcla y homogeneización de la columna de agua de la bahía, incrementándose la concentración durante el flujo de la corriente de marea en el estero. La productividad primaria fue mayor en los meses de verano, alcanzando valores hasta de 68.32 mgC/ms/h y mínimos en otoño e invierno con valores de 3.57 mgC/ms/h. Altos valores de razón de asimilación se reportan durante las mareas muertas.
