Groundwater flow and dissolved carbon movement in a boreal peatland

Measurement of the groundwater flux and the consequent advection of dissolved carbon (DOC (dissolved organic carbon), CH4 and CO2) were made in a boreal peatland in northern Sweden in summer 1993. The early summer gradients in hydraulic head indicated a downward flux of water in the peatland, but after a persistent mid-summer dry period the gradients changed to produce an outward radial flow from the centre to the margins of the peatland.
