| Popis: | Data on excess carbon dioxide partial pressures (EpCO2) in 15 major rivers and tributaries entering the North Sea are presented and compared with basin-wide information for the Humber region. Large variations are observed with values ranging from less than a tenth to over a hundred times saturation. There is a marked geographical change with median concentrations typically increasing from north (EpCO2 100 mmol/m2/day but reaching over 1000 mmol/m2/day at times. This loss is compensated for by tributary inputs and in-stream generation such as respiration of labile organic compounds derived from effluents, thus explaining the good correlation between dissolved organic carbon and EpCO2. |
