High Latitude Silica Exports

Repository Explanation

This repository contains the code needed for one sub-project created by the Long Term Ecological Research (LTER) synthesis working group: "From poles to tropics: A multi-biome synthesis investigating the controls on river Si exports"

Script Explanations

The 'core' scripts in this repository are described below. Any script not described below is exploratory and should be treated as such.

  • 00_data-download.R - Downloads the various source data from this working group's Shared Google Drive. Note that only those with access to that Drive will be able to run the script.

  • 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.

    • Assumes you have either run 00_data-download.R or manually put the needed input files in a folder named "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

    • Assumes you have run 01_sizer-workflow.R

  • 03a_stats.R - Performs desired statistical analysis

    • Assumes you have run 02_stats-prep.R

  • 03b_explore-graphs.R - Makes exploratory (i.e., not necessarily publication-quality) graphs of extracted SiZer information. Works for annual/seasonal/monthly input data

    • Assumes you have run 02_stats-prep.R

  • 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.

    • Assumes you have either run 00_data-download.R and 02_stats-prep.R

  • 04_figures.R - Makes publication-quality figures from extracted SiZer information. Written for only annual data

    • Assumes you have run 02_stats-prep.R

  • 05_tables.R - Generates publication-quality summary tables

    • Assumes you have run 03a_stats.R
