PNG images of each seismic profile were generated in order to enable incorporation of images of the seismic profiles into Geographic Information System (GIS) projects and data archives. The PNG images represent over 330 km of EdgeTech SB-512i chirp seismic-reflection profiles collected within and around Norfolk Canyon. These images are provided as a convenient and rapid method for viewing the seismic-reflection data.
