The Utility of Light-Saturation Models for Estimating Marine Primary Productivity in the Field: A Comparison with Conventional "Simulated" In Situ Methods
Primary production rates derived from model photosynthesis–light (P–l) curves and daily solar radiation data were compared with direct measurements using "simulated" in situ incubations in arctic and temperate marine waters. On the average, model estimates were slightly higher in surface w...
