Abstract

A photosynthetic quotient (PQ) for Narragansett Bay, RI, USA was calculated using concurrent 14C and oxygen lightdark bottle primary production estimations. The current PQ (1.42 ± 0.09) was elevated over the PQ (1.24) calculated in a 1980s mesocosm experiment, stimulating a sensitivity analysis of physiological drivers of the PQ. We speculate that the factor that altered the PQ between surveys was wastewater treatment facility upgrades increasing NO 3- effluent proportion from 10 to 40. © 2012 The Author.
