Abstract:	Development of the oil sands has led to increasing atmospheric N deposition, with values as high as 17 kg N ha^-1 yr^-1; regional background levels <2 kg N ha^-1 yr^-1. Bogs, being ombrotrophic, may be especially susceptible to increasing N deposition. To examine responses to N deposition, over five years, we experimentally applied N (as NH₄NO₃) to a bog near Mariana Lakes, Alberta, at rates of 0, 5, 10, 15, 20, and 25 kg N ha^-1 yr^-1, plus controls (no water or N addition). Resin tubes filled with mixed-bed ion exchange resin were swapped in and out at each collection/deployment date (mid-May and mid-October of each year). Upon collection, resins were extracted with 1M KI and analyzed for inorganic N concentrations. Deposition of NH₄ ⁺-N, NO₃ ^--N, and DIN averaged 187 ± 11, 237 ± 13, and 426 ± 19 μg m^-2 da^-1, corresponding to 0.68 ± 0.04, 0.87 ± 0.05, and 1.55 ± 0.07 kg N ha^-1 yr^-1, with no significant differences between open and throughfall collectors for any of the three measured parameters (p >= 0.63). Deposition of NH₄ ⁺-N was significantly higher during the growing season (averaging 240 μg m^-2 da^-1) than during the winter months (averaging 121 μg m^-2 da^-1) (p = 0.0004), while NO₃ ^--N and DIN deposition did not differ significantly between winter and summer (p = 0.06 and 0.13, respectively).

Methods and protocols used in the collection of this data package

Description:

We quantified atmospheric N deposition using ion exchange resin tube collectors (Fenn et al. 2003, Wieder et al. 2016b), filled with mixed bed cation/anion exchange resin (Amberlite IRN 150) that had been rinsed with deionized water prior to deployment in the field. We placed five collectors in the open and five beneath clumps of Picea mariana trees (throughfall). In addition, 2 resin tubes, sealed at the top, and placed in the field within PVC sleeves, served as blank controls. A plastic funnel with a collection area of 400 cm² channeled precipitation into the resin tubes. We collected and replaced tubes in mid-May and mid-October. For the October-May periods, we affixed a 1-m extension tube to each collection funnel to capture snowfall, which upon melt would drain into the resin tubes.

We extracted retrieved resins with 1 M KI and analyzed the extract solutions for NH₄ ⁺-N (phenate method) on a Seal AA3 AutoAnalyzer and for NO₃ ^--N by ion chromatography (Dionex ICS 1500). We subtracted volume-weighted concentrations in blank resin tube extracts from concentrations in extracts from exposed resin tubes and corrected deposition values for laboratory-determined extraction efficiencies (96.9 and 98.2 % for NH₄ ⁺-N and NO₃ ^--N, respectively; Wieder et al. 2016b).
