To provide the digital chirp seismic-reflection profile data in SEG-Y format which provides information about the sub-surface geology in the survey area as well as being able to be used in conjunction with the continuous resistivity profile (CRP) data.

The navigation system used was a Lowrance 480M with an LGC-2000 Global Positioning System (GPS) antenna. The antenna was located above the seismic towfish tow point. The system towfish was attached by a short line to a cleat on a 2 x 6 board that was clamped across the bow of the boat. The towfish was on the starboard side of the boat, approximately 0.5 meters below the water surface. GPS data are assumed to be accurate to within 10 meters.
Although bathymetry was not recorded directly with this system, bathymetry can be derived by tracing the seafloor reflector in the seismic-reflection profiles. The seismic towfish was attached to a cleat by a short line on the starboard side of the boat. The transducer draft was approximately 0.5 m below the water surface. The draft offset was not included in the data acquisition.
A SEG-Y format data file is available for every seismic-reflection profile line collected on this cruise.

The data are available in the SEG-Y format. The user must have software capable of reading this format. The online linkage is to the folder containing the SEG-Y data. The separate zip file provides the FGDC metadata. Due to the large file sizes, the SEG-Y files are only available individually from a download folder. To further reduce filesize, these SEG-Y files have been compressed, so the user must have the capability of uncompressing a zip file.
