Potential mobilization and transport of Dissolved Organic Carbon (DOC) in subarctic river basins towards the oceans is enormous, because 23-48% of the worlds Soil Organic Carbon (SOC) is stored in northern regions. As climate changes, the amount and composition of DOC exported from these basins are expected to change. The transfer 5 20 concentration found in streams. As climate changes, also flowpaths of water through soils may change, especially in tundra caused by thawing soils. Therefore,

To better understand the process of DOC ad-and de-sorption in soils, process based soil chemical modelling, which could bring more insight in solution speciation, mineral solubility, 25 and adsorption reactions, is appropriate. 3190 BGD
