Microphytobenthos potential productivity estimated in three tidal embayments of the San Francisco Bay system
Jean-Marc Guarini, James E. Cloern, Jody L. Edmunds, Philippe Gros
2002, Estuaries (25) 409-417
In this paper we describe a three-step procedure to infer the spatial heterogeneity in microphytobenthos primary productivity at the scale of tidal estuaries and embayments. The first step involves local measurement of the carbon assimilation rate of benthic microalgae to determine the parameters of the photosynthesis-irradiance (P-E) curves (using non-linear...
