Boreal river systems play a crucial role in high latitude change as they carry the highest terrestrial input of all aquatic flow to the sea, including a massive dissolved organic flux. All is injected directly into the climatologically sensitive Arctic Ocean. We performed reduced kinetic modeling for organic matter evolution along an idealized Siberian river. We studied reactivity, networking, and fate for the major macromolecular groups based on their diverse structures; sugar, protein, lipid, heteropolycondensate and humic substance are all considered. Reaction rates and concentrations for carbon compounds, which depend on upstream Arctic ecosystems, will be presented. Finally, biophysical impacts along coastlines will be estimated and discussed.
