Data and code to accompany the manuscript Venkiteswaran, Schiff, Paterson, Flinn, Shao, Elgood. 2017. Increasing Nitrogen Deposition with low δ¹⁵N-NH₄⁺ and δ¹⁵N-NO₃^- Values at the Experimental Lakes Area, northwestern Ontario, Canada. FACETS doi: 10.1139/facets-2016-0060.

Manuscript submitted October 2016. Accepted January 2017.

The raw data and R-scripts used to perform the analyses and figures are here.

• 01-data_calculations_and_figures.R: R-script to reproduce the N deposition figures and calculations
• 02-isotope_figures.R: R-script to reproduce the isotope figures
• 03-cows_pigs_fertilizer_figure: R-script for the agriculture (cows, pigs, and fertilizer) figure
• cows fertilizer pigs.csv: agriculture (cows, pigs, and fertilizer) data
• ELA N precip data for calculations.csv: raw precipitation chemistry and depths
• lake stream survey.csv: dissolved organic matter, particulate organic matter, and zooplankton isotope data
• precip amount conc delta.csv: precipitation data with concentrations and isotopes
• precip delta NH4.csv: survey of NH4+ isotope data
• precip delta NO3.csv: survey of NO3- isotope data

The R-code for the analyses, figures, and mixing models requires (at the very least) dply, ggplot2, Kendall, reshape2, and zoo. Thanks to the authors of these packages.
