Spatiotemporal Patterns in pCO₂ and Nutrient Concentration: Implications for the CO₂ Variations in a Eutrophic Lake.

ABSTRACT: Lakes are considered sentinels of terrestrial environmental change. Nevertheless, our understanding of the impact of catchment anthropogenic activities on nutrients and the partial pressure of carbon dioxide (pCO₂, an important parameter in evaluating CO₂ levels in water) is still restrained by the scarcity of long-term observations. In this study, spatiotemporal variations in nutrient concentrations (total nitrogen: TN, total phosphorus: TP, nitrate: NO₃^--N, and ammonium: NH₄⁺-N) pCO₂ in Taihu Lake were analyzed from 1992 to 2006, along with the gross domestic product (GDP) and wastewater discharge (WD) of its catchment. The study area was divided into three zones to characterize spatial heterogeneity in water qu
