Caracterización estacional y espacial de los parámetros fotosintéticos del fitoplancton del Golfo de California J. Eduardo Valdez Holguín Charles C. Trees Saúl Álvarez Borrego Ciencias de la Tierra fitoplancton Golfo de California parámetros fotosintéticos Se analizaron datos de la relación fotosíntesis/irradiancia y de absorción del fitoplancton del Golfo deCalifornia, así como datos publicados, con el objetivo de proponer valores promedio de los parámetros fisiológicos para estimar productividad primaria en escalas grandes de tiempo y espacio. Por el momento no es posible predecir variaciones de los parámetros fotosintéticos en las escalas espaciales y temporales finas. Se recomiendan los siguientes promedios para todo el Golfo de California y para condiciones de invierno (TºC superficial <22ºC): un P*max = 9.6 ± 2.4 mgC mgChl1 h1 (número de asimilación) superficial, con una variación lineal entre éste y 3.7 ± 0.3 en la mitad de la zona eufótica (ze), y luego un valor constante para aguas más profundas; un solo valor de α*inc = 0.029 ± 0.004 mgC mgChl1 h1(µmol cuanta m2 s1)1 (pendiente inicial de incubador); y φmax = 0.06 ± 0.01 molC (mol cuanta)1 (eficienciacuántica de la fotosíntesis). Para condiciones de verano se recomiendan: un P*max = 3.7 ± 0.3superficial, con una variación lineal entre éste y 1.5 ± 0.2 en la mitad de la ze, y otra variación lineal entre la última y 0.4 ± 0.1 en el fondo de la ze; una α*inc = 0.013 ± 0.001 superficial, con una variación linealentre ésta y 0.001 en el fondo de la ze; y un solo valor φmax = 0.014 ± 0.002. Se presenta un procedimientopara corregir α*inc por la distribución espectral de la luz in situ y obtener α*in situ. 1999 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48025401 es http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.4 Vol.25
