Description:
Understanding linkages between river chemistry and biological production in arctic coastal waters requires improved estimates of riverine nutrient export. Here we present the results of a synthesis effort focusing on relationships between watershed slope and seasonal concentrations of river-borne dissolved organic carbon (DOC), dissolved organic nitrogen (DON), and nitrate ( ##IMG## [http://ej.iop.org/images/1748-9326/13/10/104015/erlaae35dieqn1.gif] {${{{\rm{NO}}}_{3}}^{-}$} ) around the pan-Arctic. Strong negative relationships exist between watershed slope and concentrations of DOC and DON in arctic rivers. Spring and summer concentration-slope relationships for DOC and DON are qualitatively similar, although spring concentrations are higher. Relationships for ##IMG## [http://ej.iop.org/images/1748-9326/13/10/104015/erlaae35dieqn2.gif] {${{{\rm{NO}}}_{3}}^{-}$} are more variable, but a significant positive relationship exists between ...
