Temporal variability of primary productivity, chlorophyll and seston in Bahia de Los Angeles, Gulf of California

With the aim of studying the short variability of seston, chlorophyll a and primary productivity of phytoplankton, water samples were taken in Bahía de los Ángeles during nine days of February and March, 1987. Chlorophyll a had higher values during spring tides, with variations between 0.25 to 9.70...

Chlorophyll a had higher values during spring tides, with variations between 0.25 to 9.70 mg·m–3. Total seston was mainly formedby organic matter, almost without an inorganic contribution, except when the speed of the wind was >8 m·s–1. Primary productivity increased from spring tides to transitional and neap tides, with 115, 243 and 337 mg·Cm–2·h–1, respectively. A linear relationship was found between primary productivity (P) and chlorophyll a concentration (Cla): P = 4.76Cla-0.91. Horizontal advection and vertical mixing both originated from the wind effect and appear to be the main processes that determine variability of phytoplankton biomass and primary productivity in the bay La concentración de clorofila, el seston y la productividad primaria del fitoplancton se muestrearon durante nueve días de febrero y marzo de 1987, para describir su variabilidad en un punto de la Bahía de los Ángeles. La clorofila a tuvo mayores concentraciones en mareas vivas, con un intervalo de variación en la serie de tiempo entre 0.25 a 9.70 mg·m–3. El seston estuvo principalmente compuesto por material orgánico, sin una contribución aparente de material inorgánico, excepto cuando la velocidad del viento fue mayor a 8 m·s–1. La productividad primaria se incrementó de mareas vivas, transicionales a mareas muertas, con valores de 115, 243 y 337 mg·Cm–2·h–1, respectivamente. Debido a las condiciones hidrográficas de la bahía se determinó una relación lineal entre la productividad primaria (P) y la concentración de clorofila a (Cla) de la forma: P = 4.76 Cla -0.91. El transporte horizontal y la mezcla vertical originadas por el efecto del viento parecen ser los factores principales que regulan la variabilidad de la biomasa y la productividad primaria del fitoplancton en la bahía.
