a, Silicate10versus OCpetroweathering fluxes and their net values. Basins that produce a net source of CO2are shown in the shaded half of the plot, with the net magnitude of the weathering CO2flux illustrated by the symbol colour (in MtC yr−1).b,c, Net weathering balance versus basi...
Carbon dioxide flux was measured in March 2007 at the surface of the volcanic lake of El Chichón volcano, Mexico using the floating accumulation chamber method. The results of 162 measurements and the application of a standard statistical approach developed for these studies showed that the total ...
During the 5 years of grazing, the CO2emissions rate changed greatly among the different grazing treatments (Fig.1C). Over time, the CO2flux of the grasslands decreased significantly with increased grazing intensity. Relative to the control, the CO2fluxes under different grazing intensities decreased...

Lake Taihu is a significant CO2 source with an annual CO2 flux of 0.7 ± 0.3 Tg yr1. The highest CO2 level occurred in eutrophic zone and low in non-eutrophic zone. The annual lake CO2 dynamics highly sensitive to human-induced external input. Abstract Inland lakes receive growing attentions...

allowed identifying a deep CO2flux of ~10 Mt yr−1. The origin of this CO2discharging in central Italy is still debated: Marini and Chiodini8and Chiodini et al.3proposed a mix of mantle and a crustal-derived components; Minissale9favored a mantle-derived CO2origin; Italiano et al.10...
