Industrial legacies in a rapidly changing Arctic

<strong>Database and source codes used to investigate the impact of permafrost thaw on industrial legacies in the Arctic:</strong> The file <em>Industrial_Sites.zip</em> includes geospatial data (point shape file) on the location of industrial sites above 55°N. The data synergizes data from OpenStreetMap (OSM) and the Nordregio Atlas of population, society and economy in the Arctic from 2019. The file <em>Contaminated_Sites_Program_Alaska.zip</em> includes geospatial data extracted from the database of the Contaminated Sites Program in Alaska. The data set contains location, associated industrial sector, first date of registration, and associated chemical substances. The file <em>Contaminated_Sites_Canada.zip</em> includes geospatial data extracted from the database of the Federal Contaminated Sites Inventory (FCSI) of Canada. The data set contains besides location and the local permafrost probability, additional information on contamination type and the treatment status. The file <em>Contaminated_Sites_Russia.zip</em> contains geodata about industrial contamination events in Russia. The dataset was created based on a Google search using keywords in Russian ("загрязнение" - pollution; "разлив нефтепродуктов" - oil spill; "техногенная авария" - industrial accident or disaster; "Арктика" - Arctic; "мерзлота" - permafrost) and a search of several online media (including local and federal news portals). The database includes the locations of contamination events, the date, and information about the type of event, as well as the link to the media source. In some cases, the contaminated area and volume of the spill are also provided. The file<em> Point_Process_Modeling.zip</em> contains geospatial data of industrial sites and contaminated sites in Alaska and Canada and an R script used to fit two point process models to the data. The results deliver intensity maps of contaminated sites in the Arctic permafrost region. The file <em>PanArctic_Simulations.zip</em> includes the source code of the CryoGrid permafrost model (Julia Language v. 0.6.4) and a start script with all parameters and forcing data (JSON) required to run the model for industrial sites located in the Arctic permafrost region. The file<em> Analysis_Industrial_Contaminated_Sites_Arctic.zip</em> contains data and scripts to analyze permafrost degradation at industrial sites and contaminated sites in the Arctic following the simulations performed with PanArctic_Simulations.zip and the site locations contained in <em>Industrial_Sites.zip</em> and the intensity map derived by <em>Point_Process_Modelling.zip</em>. The file<em> Geospatial_DataCollection.zip</em> contains the complete database <em>used to analyze and visualize the occurences of industrial contaminations in the Arctic</em>. The file<em> Visualization_Geospatial_DataCollection.zip</em> contains a collection of additional python scripts used to plot data and analysis results contained in <em>Geospatial_DataCollection.zip</em>. Please note that all paths pointing to the datasets used in the scripts have to be changed accordingly.
