Short summary
Air-water CO2 fluxes were monitored in Guanabara Bay (Brazil), a tropical eutrophic coastal embayment. In contrast to other estuaries worldwide, Guanabara Bay behaves as an annual CO2 sink (-9.6 to -18.3 molC m2 yr) due to the concomitant effects of strong radiation, thermal stratification, and high availability of nutrients, which promotes huge phytoplankton development and autotrophy. Our results show that CO2 budget assertions still lack information on tropical marine-dominated estuaries.
