Abstract or Summary
  • Headwater streams comprise nearly 90% of the total length of perennial channels in global catchments. They mineralize organic carbon entering from terrestrial systems, evade terrestrial carbon dioxide (CO₂ ), and generate and remove carbon through in-stream primary production and respiration. Despite their importance, headwater streams are often neglected in global carbon budgets primarily because of a lack of available data. We measured these processes, in detail, over a 10 year period in a stream draining a 96 ha forested watershed in western Oregon, USA. This stream, which represents only 0.4% of the watershed area, exported 159 kg C ha⁻¹ yr⁻¹, similar to the global exports for large rivers. Stream export was dominated by downstream transport of dissolved inorganic carbon (63 kg C ha⁻¹ yr⁻¹) and by evasion of CO₂ to the atmosphere (42 kg C ha⁻¹ yr⁻¹), leaving the remainder of 51 kg C ha⁻¹ yr⁻¹ for downstream transport of organic carbon (17 kg C ha⁻¹ yr⁻¹ and 34 kg C ha⁻¹ yr⁻¹ in dissolved and particulate form, respectively)
