“…Xiangxi Bay of TGR has an approximate CH 4 flux to the Middle Yangtze River 24 , both of which are in the subtropical climate zone. CH 4 fluxes in the TGR are much smaller than those data from water bodies of tropical zone such as Petit Saut and Miranda 33 34 , but larger than those from the reservoirs in temperate zone and frigid zone such as Quebéc and Lokka 6 11 . This verifies that CH 4 emissions were correlated to latitude 3 .…”

Indoor simulation experiment was carried out to evaluate the formation and consumption rates of methane (CH4) in Xiangxi Bay of the Three Gorges Reservoir (TGR), China. The results show that both the CH4 formation and consumption rates were significantly positively correlated with temperature. CH4 efflux decreased with rising temperature due to its potential increasing oxidation rate. CH4 oxidation in surface sediments accounted for 51.8% of the total production and it even reached to 77.4% at 35°C. The methane oxidation rate in water column ranged from 1.26 to 4.65 mg/(m2h), of which the average and greatest rate accounted for 46.7% and 73.9% of CH4 production respectively under the condition of 30 m water column and 35°C. The methane oxidation may increase by 41.04 mg/(m2h) under average water level of TGR (160 m), and most methane resulted from sediments can be oxidized in the water column.

“…Hydroelectric reservoirs do not have a negligible carbon footprint, in other words, they are not carbon-free 3 . CH 4 emissions from hydroelectric reservoirs might have an influence on the anthropogenic CH 4 4 5 6 7 8 9 10 11 . Moreover, some reservoirs emit more carbon than fossil-fuel based electricity 12 .…”

“…CO 2 and CH 4 emissions are known to increase rapidly after flooding, generally to about five times the values measured in natural aquatic ecosystems. Within a period of 10 years for CO 2 and five years for CH 4 , the emission rates decrease rapidly to values typical of natural aquatic ecosystems (5,6,16). Because flooded trees decompose very slowly, emitted CO 2 and CH 4 are due primarily to the decomposition of the fraction of the labile organic matter in flooded soils.…”

Growing concern over the contribution of freshwater reservoirs to increases in atmospheric greenhouse gas (GHG) concentrations and the relevance of long-term continuous measurements has led Fisheries and Oceans Canada, in conjunction with Manitoba Hydro, to develop continuous GHG monitors. Continuous water pCO(2), pCH(4), and pO(2) measurements were gathered to estimate gas fluxes in one temperate reservoir (Riviere-des-Prairies) and two boreal reservoirs (Eastmain-1 and Robert-Bourassa) in Quebec, and in four boreal reservoirs (Grand Rapids, Jenpeg, Kettle, and McArthur Falls) in Manitoba, Canada. Mean daily CO(2) fluxes ranged between 7 and 14 mmolCO(2)*m(-2)*d(-1) in Manitoba and between 15 and 55 mmolCO(2)*m(-2)*d(-1) in Quebec. Summertime episodes of water undersaturation in CO(2) were observed at Jenpeg, Kettle, and McArthur, suggesting higher productivities of these systems compared to the other systems studied. Mean daily CH(4) fluxes ranged between 0 and 69 micromolCH(4)*m(-2)*d(-1) in Manitoba and between 9 and 48 micromolCH(4)*m(-2)*d(-1) in Quebec. Comparisons of results obtained in the Eastmain-1 area using automated monitors, floating chambers or dissolved gas analyses over multiple-station field campaigns demonstrated that a continuous GHG monitor at a single sampling station provided representative and robust results.

“…Whereas CO 2 concentration increased from 280.0 to 389.0 ppm from 1800 to 2010 (Tarasova et al 2012), CH 4 increased from approximately 0.7 to 1.8 ppm from 1999 to 2005 (Forster et al 2007). Global warming due to increasing concentrations of LLGHGs in the atmosphere is likely to affect ecosystem structure and functioning, and many studies have focused on CO 2 and CH 4 fluxes across the water−air interface in aquatic ecosystems, including oceans, rivers, reservoirs, and lakes (Smith et al 2000, Huttunen et al 2002, Bange 2006, Hirota et al 2007, Zhang et al 2008, Tremblay & Bastien 2009, Koné et al 2010. Although several studies have considered CO 2 and CH 4 fluxes across the sediment− water interface in these aquatic systems (Moosavi et al 1996, Liikanen & Martikainen 2003, Adams 2005, Huttunen et al 2006, data on freshwater aquaculture ponds are still limited.…”

Benthic fluxes of carbon dioxide (CO 2 ) and methane (CH 4 ) were evaluated in grass carp Ctenopharyngodon idella (G), silver carp Hypophthalmichthys molitrix (S), and bighead carp Aristichthys nobilis (B) polyculture systems, to which topmouth culter Erythroculter ilishaeformis (T), Pacific white shrimp Litopenaeus vannamei (P), or common carp Cyprinus carpio (C) were added. These systems, GSBT, GSBP, and GSBC, respectively, were monitored over 5 mo (May to September 2014). The presence of L. vannamei and C. carpio increased CO 2 and CH 4 emissions in GSBP and GSBC, respectively. From June to August, CO 2 and CH 4 fluxes increased in the 3 systems, and in July and August these fluxes were significantly higher in GSBC than in GSBP and GSBT, and significantly higher in GSBP than in GSBT. The metabolisms of L. vannamei and C. carpio contributed to decrease dissolved oxygen, pH, and oxidation−reduction levels, and the bioturbation of the upper sediment layers caused by these species increased organic matter degradation rate, resulting in a significant increase in particulate and dissolved organic carbon in the overlying water. Our results indicate that improving feeding efficiency and reducing organic carbon accumulation on the bottom of aquaculture ponds, as well as increasing dissolved oxygen and decreasing bioturbation across the sediment−water interface during farming seasons, is likely to reduce CO 2 and CH 4 release from aquaculture pond sediment, especially in July and August.
