Both of these maps were made with the GMT program using bathymetry extracted from the GMRT MapTool. The land topography in the second map is high resolution (30 m pixel) data obtained from the Shuttle Radar Topography Mission.
Here are maps showing our planned MT and seismic stations.
This map shows all the planned MT stations and the regional tectonic framework. The main marine MT profile is about 300 km long and will target the formation of melts beneath the volcanic arc as the Pacific tectonic plate subducts beneath the North American tectonic plate. The MT data will also be used to constrain the hydration state of the forearc mantle wedge and the back-arc mantle.
This map shows a close up of the MT stations on and around the island (red squares) as well as the 12 new seismic stations we will collect (white triangles). The ring of stations around the flanks of the volcano will be used to image the melt delivery to the deep crust of the volcanic arc. The stations in the caldera will be used to image melt storage in the upper part of the crust. The nonlinear color scale for the seafloor topography was used to highlight regions of shallow water, where white to magenta colors denote 25 to 0 m water depths. This was done to check that the marine stations are in deep enough water since in shallow water wave induced noise can ruin the MT recordings.
