Files used in a Monte Carlo analysis of oil spill risks in the Salish Sea

This dataset contains input files, configuration parameters, parameter statistics, and aggregated model outputs generated for a Monte Carlo analysis of oil spill risk in the Salish Sea. The dataset was used to develop thousands of hypothetical oil spill scenarios based on observed vessel movement patterns in 2018, recorded oil transfer operations in 2018, and historical spill data. It includes sets of 10,000 synthetic spill scenarios as well as underlying data sources used to generate the statistics from which spills were derived. The files are organized into folders that include: aggregated model output from a set of 10,000 spills, sets of spill scenarios generated by our method, YAML configuration files, gridded "Vessel Time Exposure" maps in GeoTIFF format, and annotated spreadsheets with information used to inform methodology. The dataset is the result of an interdisciplinary effort to more comprehensively represent oil spill risks in the coastal waters between Vancouver Island and the mainlands of British Columbia and Washington State. It reflects a detailed integration of vessel traffic data, empirical spill records, and operational infrastructure characteristics. Due to licensing constraints, AIS ship track data from SPIRE Maritime is excluded but referenced. Please see the companion articles “A statistical representation of oil spill fate in the Salish Sea (Parts 1 & 2)” published in Marine Pollution Bulletin (Mueller et al., 2025). Source code used for simulation and analysis is openly available on GitHub (https://github.com/MIDOSS/MuellerEtAl_MIDOSS_paper) and archived via Zenodo (https://doi.org/10.5281/zenodo.10939119).
