These PNG images represent approximately 420 km of chirp seismic-reflection data collected by the U.S. Geological Survey during cruise 2017-003-FA along the Mississippi River Delta front offshore of southeastern Louisiana. Images of each seismic profile were generated in order to provide portable and easily viewable alternatives to the SEGY versions of the data. Each profile image can be hotlinked to its corresponding trackline navigation contained within the Esri polyline shapefile '2017-003-FA_512i_Tracklines.shp'. Shotpoint index marks along the top of the PNG images correlate to the positions of 500 shot intervals within the Esri point shapefile '2017-003-FA_512i_500sht.shp'.
