Introduction

This repository contains source code for the paper:

Geyman, B.M., D.G. Streets, C.I. Olson, C.P. Thackray, C.L. Olson, K. Schaefer, D.P. Krabbenhoft, and E.M. Sunderland (2025). Cumulative Anthropogenic Impacts of Past and Future Releases on the Global Mercury Cycle. Environmental Science & Technology

Anthropogenic emissions/releases and compiled seawater mercury data used in the analysis are stored separately on Harvard Dataverse and can be downloaded to the repository directory using fetch_data.sh. Code to support box modeling is located in a separate GitHub Repository and can be installed through the method outlined below.

The script install_environment.sh creates a conda environment called pyboxey_env that installs python and all dependencies needed to run the code. The script call_all.sh executes the complete analysis in sequence.
