Short summary
In this paper, we focus on key, poorly understood properties of carbonate geochemistry in one of the largest estuaries in North America. We explore how varying environmental factors impact estuarine inorganic carbon fluxes and seasonal net ecosystem production. Comparisons with long-term records highlight the significance of tributary inputs as well as a regional shift towards increased riverine bicarbonate concentrations.
