Description In March of 2009, the U.S. Geological Survey and Texas A&M University at Galveston conducted geophysical surveys to investigate the shallow geologic framework from Sabine Pass to Galveston, TX, as part of the USGS's Coastal Change and Transport (CCT) study. This report serves as an archive of unprocessed digital Chirp sub-bottom profile data, trackline maps, navigation files, GIS information, FACS logs, observer's logbook, and formal FGDC metadata. Gained digital images of the sub-bottom profiles are also provided. The archived trace data are in standard SEG-Y format (Barry and others, 1975) and may be downloaded and processed with commercial or public domain software such as Seismic Unix (SU). Example SU processing scripts and USGS software for viewing the SEG-Y files (Zihlman, 1992) are also provided. For more information on the seismic surveys see These data are also available via GeoMapApp ( and Virtual Ocean ( earth science exploration and visualization applications. [More]
