Unformatted text preview: ediments: ~66% Organic Carbon: “CH2O” (Living + Dead Biomass; ~2%) Inorganic Carbon: primarily HCO3- (bicarbonate; ~97%) What kind of C is in each reservoir? Atmosphere: Carbon Dioxide: CO2 (>99%) Methane (CH4) (most of remainder) Land Biosphere: Hydrosphere: (oceans) Lithosphere: Organic Carbon: “CH2O” (Note – this is simplified formula for biomass. Biomass is organic carbon.) Living Biomass: ~33% Dead Biomass in soils & sediments: ~66% Organic Carbon: “CH2O” (Living + Dead Biomass; ~2%) Inorganic Carbon: primarily HCO3- (bicarbonate; ~97%) Organic Carbon: (sedimentary organic carbon, coal, tars, oils, natural gases. < 25%) Inorganic Carbon: (carbonate rocks: CaCO3 (limestones) (Ca,Mg)CO3 (dolomites)) > 75% Nine Fluxes: What are they? 1a: 63 Gt/y 8 7 land bioshpere (2200 Gt) 6 atmosphere (800 Gt) lithosphere (78,000,000 Gt) 1b: 4 5 Gt/ y 2b hydrosphere (38,400 Gt) 1a: Photosynthesis (land): CO2 + H2O à༎ CH2O +...
