Data on carbon, nitrogen, and phosphorus forms in a north temperate river, Rivière du Nord [Québec, Canada, 2017-2019]

Sites are numbered by river kilometer (RKm) with the outlet being RKm 0. The dataset includes concentrations (ug/L or mg/L as noted) of total organic carbon, dissolved organic carbon, particulate organic carbon, total nitrogen, total dissolved nitrogen, nitrate, ammonium, dissolved organic nitrogen, total phosphorus, total dissolved phosphorus and particulate phosphorus.

It also includes fluorescence metrics derived from PARAFAC EEMs: fluorescence intensities (in Raman units) of 5 dissolved organic matter components (C1-C5), and 5 indices (SUVA-254, CDOM, FI, b:a, HIX). We sampled an additional 12 sites to act as endmembers (5 mainly forested sites, 5 mainly agricultural sites, and 2 wastewater treatment plant measures). Data were used to calculate C:N:P stoichiometry in the paper "Different forms of carbon, nitrogen, and phosphorus influence ecosystem stoichiometry in a north temperate river across seasons and land uses" (doi.org/10.1002/lno.11960).
