PNG images of each chirp seismic profile were generated to integrate the seismic profiles into Geographic Information System (GIS) projects and are used to define the river-bed morphology as part of a mapping project in the Connecticut River. The PNG images represent approximately 230 km of EdgeTech 424 chirp seismic-reflection data collected by the U.S. Geological Survey during USGS survey 2012-024-FA in the Connecticut River.

These data can be viewed with any PNG image viewing software. The zip files must be uncompressed in order to view the PNG images. The zip file also contains associated metadata. The user must have software capable of uncompressing the zip file and displaying the PNG images. To use these images in conjunction with geospatial data (e.g. hotlinked to the seismic tracklines data in ArcGIS), a geospatial data viewer must be used.
