Dataset and Markdown codes for article "Long-term nitrogen burial exceeds denitrification in global fjords"

This repository contains the compiled dataset of new and referenced observations of fjord nitrogen loss processes, and the R Markdown files required to conduct spatial weighted bootstrap analyses.

The dataset (in data_file) includes empirical observations in global fjords of geochemical characteristics and processes (NAR_data.csv), microbial nitrogen cycling rates (N2_data.csv), as well as sediment nitrogen cycling rate measurements in seasonal hypoxic fjord - Gullmar Fjord, Sweden (gullmar_data.csv). Units and remarks of each dataset are found in the corresponding *_metadata.csv files. These dataset were used to generate figures in the article and to perform all statistical analyses.

Shapefiles (in shp_file) are used to generate base map and highlight major fjord regions in plots.

The R code used to perform spatial weighted bootstrap analyses (in spatial_weighted_bootstrap) is available in R Markdown format and rendered as HTML and PDF files. Data and shape files that required to perform the analyses and the visualization can be found in data_file and shp_file.
