Does the Sverdrup critical depth model explain bloom dynamics in estuaries? Does the Sverdrup critical depth model explain bloom dynamics in estuaries?
In this paper we use numerical models of coupled biological-hydrodynamic processes to search for general principles of bloom regulation in estuarine waters. We address three questions: what are the dynamics of stratification in coastal systems as influenced by variable freshwater input and tidal stirring? How does phytoplankton growth respond to these dynamics? Can the classical Sverdrup...

An empirical model of the phytoplankton chlorophyll : carbon ratio-the conversion factor between productivity and growth rate An empirical model of the phytoplankton chlorophyll : carbon ratio-the conversion factor between productivity and growth rate
We present an empirical model that describes the ratio of phytoplankton chlorophyll a to carbon, Chl: C, as a function of temperature, daily irradiance, and nutrient-limited growth rate. Our model is based on 219 published measurements of algal cultures exposed to light-limited or nutrient-limited growth conditions. We illustrate an approach for using this estimator of Chl: C to...
