The Carbonate Chemistry of Green Lake, Jamesville, NY

Abstract

The temporal and vertical distributions of inorganic carbon and related forms were assessed for the mixolimnion of Green Lake, Jamesville, NY based on a biweekly monitoring program conducted for a 14-month period. The daily time structure of the distributions was delineated for a single diurnal cycle. Attendant [H2CO3] ([H2CO3] + [CO2 (aq)]) and calcite equilibrium conditions were determined through a solution of equilibrium equations, adjusted for temperature and ionic-strength. Inorganic carbon equilibrium conditions within the iron-rich chemocline/monolimnion were evaluated with the aid of a computer model, which incorporated ion-pair interactions, utilizing data obtained from a single sampling.
