Des matrices d'émission d'excitation (EEM) ont été utilisées dans la modélisation des facteurs parallèles (PARAFAC) pour déconstruire et identifier les composants fluorophores individuels du DOM. Les résultats du modèle de cette analyse PARAFAC peuvent être consultés en ligne à l'adresse www.openfluor.org. \n\nLe débit du cours d'eau a été mesuré en développant des courbes de débit d'étage à une station hydrométrique fixe à proximité de la sortie. Le flux de COD a été estimé à l'aide de plusieurs méthodes de régression dans l'ensemble R le plus rapide en combinant les concentrations de COD avec un débit continu de 15 minutes de chaque bassin versant.

Samples were run for analysis of dissolved organic carbon (DOC), iron (Fe), and optical characterization of dissolved organic matter (DOM) using spectrofluorometry. Excitation emission matrices (EEMs) were used in parallel factor modeling (PARAFAC) to deconstruct and identify individual fluorophore components of DOM.  Model output from this PARAFAC analysis can be found online at www.openfluor.org. \\n\\nStream discharge was measured by developing stage discharge rating curves at a fixed hydrometric station in proximity to the outlet. DOC flux was estimated using multiple regression methods in the R package rloadest by combining DOC concentrations with 15-minute continuous stream discharge from each watershed. Loads for October 1, 2015 through April 30, 2016 are presented for each watershed in average kilograms per day. Further details on the development and analysis of stage discharge rating curves and multiple regression models used for estimating DOC flux can be found in Oliver et al. 2017\\n\\nOliver, A.A., S.E.

Chemistry and discharge data were collected from the stream outlet stations of the seven focal watersheds at the Hakai watersheds observatory on Calvert and Hecate Islands, British Columbia Central Coast.\n\nBrief summary of methods\nFor detailed information on sample collection and methods of analysis please refer to Oliver et al. 2017.\n\nStream water grab samples were collected every 2-3 weeks (or ~monthly in winter) from May 2013 to July 2016 (n= 402) from stream outlets of the seven focal watersheds monitored within the Kwakshua Channel watersheds. Samples were run for analysis of dissolved organic carbon (DOC), iron (Fe), and optical characterization of dissolved organic matter (DOM) using spectrofluorometry. Excitation emission matrices (EEMs) were used in parallel factor modeling (PARAFAC) to deconstruct and identify individual fluorophore components of DOM.  Model output from this PARAFAC analysis can be found online at www.openfluor.org. \n\nStream discharge was measured by developing stage discharge rating curves at a fixed hydrometric station in proximity to the outlet. DOC flux was estimated using multiple regression methods in the R package rloadest by combining DOC concentrations with 15-minute continuous stream discharge from each watershed. Loads for October 1, 2015 through April 30, 2016 are presented for each watershed in average kilograms per day. Further details on the development and analysis of stage discharge rating curves and multiple regression models used for estimating DOC flux can be found in Oliver et al. 2017\n\nOliver, A.A., S.E.

Les données sur la chimie et le débit ont été recueillies auprès des stations de sortie des cours d'eau des sept bassins versants focaux de l'observatoire des bassins versants Hakai sur les îles Calvert et Hécate, sur la côte centrale de la Colombie-Britannique.\n\nBref résumé des méthodes\nPour des informations détaillées sur le prélèvement d'échantillons et les méthodes d'analyse, veuillez consulter Oliver et al. 2017.\n\nDes échantillons prélevés au prélèvement d'eau des cours d'eau ont été prélevés toutes les 2 à 3 semaines (ou ~ tous les mois en hiver) de mai 2013 à juillet 2016 (n = 402) dans les points de sortie des sept bassins versants focaux surveillés dans les bassins versants du chenal Kwakshua. Des échantillons ont été analysés pour l'analyse du carbone organique dissous (COD), du fer (Fe) et la caractérisation optique de la matière organique dissoute (DOM) par spectrofluorométrie. Des matrices d'émission d'excitation (EEM) ont été utilisées dans la modélisation des facteurs parallèles (PARAFAC) pour déconstruire et identifier les composants fluorophores individuels du DOM. Les résultats du modèle de cette analyse PARAFAC peuvent être consultés en ligne à l'adresse www.openfluor.org. \n\nLe débit du cours d'eau a été mesuré en développant des courbes de débit d'étage à une station hydrométrique fixe à proximité de la sortie. Le flux de COD a été estimé à l'aide de plusieurs méthodes de régression dans l'ensemble R le plus rapide en combinant les concentrations de COD avec un débit continu de 15 minutes de chaque bassin versant. Les charges pour la période du 1er octobre 2015 au 30 avril 2016 sont présentées pour chaque bassin versant en kilogrammes moyens par jour. De plus amples détails sur le développement et l'analyse des courbes d'évaluation du débit des étages et des multiples modèles de régression utilisés pour estimer le flux de COD peuvent être trouvés dans Oliver et al. 2017\n\nOliver, AA, SE Tank, I.
