AB: Wetlands play a large role in the cycling of DOC in northern landscapes from the land surface to aquatic ecosystems and there is a strong relationship between stream DOC export or concentration and proportion of the watershed occupied by peatland. These relationships have developed through the production potential for DOC from plant tissues and peat, the hydrologic transport mechanisms and the general lack of strong retention mechanisms in peatlands and other wetlands. I examine our knowledge of the atmospheric import, internal production, adsorption by mineral soils and export of DOC in northern peatland/upland systems from Ontario, Michigan and Finland and northern Manitoba.
