This dataset contains shotpoint and trackline navigation, profile images, and raw SEG-Y trace data for approximately 222 km of EdgeTech 512i chirp seismic-reflection data collected by the U.S. Geological Survey during USGS field activity 2017-002-FA (also referred to as HRS1713) along the U.S. Atlantic continental shelf break and upper continental slope between Accomac and Keller Canyons. Images of each seismic profile were generated in order to provide portable and easily viewable alternatives to the SEG-Y versions of the data. Each profile image can be hyperlinked to its corresponding trackline navigation contained within the Esri polyline shapefile '2017-002-FA_SB512iTracklines.shp'. Shotpoint index and tick marks along the top of the PNG images correlate to the positions of 100 shot intervals within the Esri point shapefile '2017-002-FA_SB512i_sht100.shp'. This information allows for spatial correlation of chirp seismic-reflection profiles images with other geophysical and sample data for investigating sea-floor morphology and stratigraphy in the area.
