Evaluating long-term change in river nutrients and stoichiometry

Script Explanations

All scripts listed below assume that you have run the preceding number script. Scripts with both numbers and letters all require that you run the preceding numbered script but do not have requirements of the other letters that use the same number (i.e., 03a and 03b both require that you have run 02 but don't require one another).

• 01_sizer-workflow.R - Runs SiZer workflow to identify changes in slope for WRTDS time series. Works for monthly, seasonal (averaged across sub-season months), and annual input data.
• 02_stats-prep.R - Combines various data files and calculates covariate columns likely to be useful in the analysis script. Just like 01_sizer-workflow.R, works for annual/seasonal/monthly input data
• 03a_stats.R - Performs desired statistical analysis
• 03b_explore-graphs.R - Makes exploratory (i.e., not necessarily publication-quality) graphs of extracted SiZer information. Works for annual/seasonal/monthly input data
• 03c_site-map.R - Creates a map of the sites with an included permafrost raster for additional context. Also points are colored by mean Si concentration
• 03d_land-rock-graphs.R - Makes simple graphs of element concentration against lithology/land cover categories
• 03e_figures.R - Makes publication-quality figures from extracted SiZer information
• 04_tables.R - Generates publication-quality summary tables
• 06_network-position.R - Calculates each site's downstream position in the HydroRIVERS network. Methods, outputs, and column definitions are in README_network-position.md.
