Webyears the second largest component is the loss of DOC from the peat profile (+39 Mg C/km2/yr). Direct exchanges of C with the atmosphere average −89 Mg C/km2/yr in the catchment. Extrapolating the general findings of the carbon budget across all UK peatlands results in an approximate carbon balance of −1.2 Tg C/ WebThis study uses long-term water chemistry records for a circum-neutral peat stream to reconstruct a 7-year record of dissolved CO 2 and DIC flux from the catchment. Combining catchment flux with a knowledge of in-stream metabolism and gas evasion from the stream surface enables an estimate of the dissolved CO 2 content of water emerging from the …

WebThis study considers three long records of dissolved organic carbon (DOC) flux from two catchments with peat-covered headwaters. The catchments vary in size from 11 to 818 km 2 and the records are at least 12 years old, with one record going back to 1965. WebAug 1, 2003 · The carbon budget of upland peat is viewed as a summation of the following fluxes ( Fig. 2 ); Inputs: – CO 2 sequestration from the atmosphere by primary production; – input of DOC and inorganic carbon as part of rainwater; and – input of inorganic carbon from weathering of underlying strata. Outputs: –
