PNG images of each chirp seismic profile were generated to integrate the seismic profiles into Geographic Information System (GIS) projects. The PNG images represent approximately 1920 km of EdgeTech SB-512i chirp seismic-reflection profiles collected south of Marthas Vineyard and north of Nantucket, Massachusetts. Each profile image can be hotlinked to its corresponding trackline navigation contained within the Esri polyline shapefile '2013-003-FA_512i_shottrack.shp'. Even 500 shot index markers along the top of the PNG images correlate to the positions of 500 shot intervals within the Esri point shapefile '2013-003-FA_512i_shot500.shp'.The trackline and shotpoint shapefiles can be found online at http://pubs.usgs.gov/of/2016/1168/ofr2016-1168-data_catalog.html
