• Abstract: Step-by-step instructions walk users through working with data from a seismic wave model in a freely available GIS (geographic information system) program, ESRI's ArcVoyager SE. Users generate and examine maps and produce graphs to explore variations in seismic wave velocities at depths of 28 and 100 km below Earth's surface. By examining and analyzing GIS-ready data, users visualize density changes and earthquake distributions near a spreading center and two subduction zones. Finally, users will infer the location (depth) of the upper mantle under ocean basins and under continents from their analyses.
