Cape Canaveral, Florida, seismic chirp collected in 2016 by Coastal Carolina University

The naming convention used for each subbottom line is as follows: CC##, where '##' are the last two digits of the track line number. The seismic source utilized during the Coastal Carolina University survey consisted of an EdgeTech 512i chirp towfish running DiscoverSB v. 4.09 acquisition software and towed about 2 meters (m) below the surface, while being floated on poly balls approximately 20 m behind the vessel. The Global Positioning System (GPS) antenna was located approximately 5.5 m above the water surface and approximately 13 m fore of the stern of the vessel. The data were acquired using a frequency sweep of 2 to 12 kilohertz (kHz), a 46 kHz sample frequency, a 20 milliseconds (ms) sweep length, and an original record length time window of 0-0.15 seconds The survey speed ranged from 4.5 to 5 knots. The binary portion of the unprocessed seismic data is stored in the Society of Exploration Geophysicists SEG Y rev. 0 (Barry and others, 1975), IEEE floating format, which is a standard digital format that can be read and manipulated by most seismic processing software packages; the first 3,200 bytes of the file header are in in American Standard Code for Information Interchange (ASCII) format instead of Extended Binary Coded Decimal Interchange Code (EBCDIC) format. The SEG Y formatted trace files have a .sgy extension. The SEG Y files may be downloaded and processed with commercial or public domain software such as Seismic Unix (SU) (Cohen and Stockwell, 2010). Also provided are printable Joint Photographic Experts Group (JPG) images of each profile. Note, file CC38.jpg doesn't exist as it is a very small file (27 traces, in a 309 KB file). The line may have been terminated for acquisition issues.
