Seismic Data

This page contains GIF thumbnail images for all the seismic profiles collected during Cruise 99SCE01. To view a full size version of the profile just click on the desired thumbnail and a full size GIF image will appear. These profiles were produced using SU software. These data were processed using a bandpass filter of 300-500-2500-3000 Hz followed by an automatic gain (AGC). However, the SEG-Y files contained on these discs are unprocessed field records. The SU processing scripts used to process these profiles are located in the SEISUNIX subfolder of the SOFTWARE folder located at the top level of the CD-ROM. These are provided for example purposes only. They may not run on every Unix or Linux platform.
NOTE: The actual SEG-Y data files are too large to fit on one CD-ROM, so we have distributed the SEG-Y data files in sequential order by complete trackline, as shown in the table below.

Disc 1: SEG-Y files for tracklines: sc9968_1 - sc9968_5

Disc 2: SEG-Y files for tracklines: sc699_6 - sc699_13

Disc 3: SEG-Y files for tracklines: sc699_14 - sc699_19

Disc 4: SEG-Y files for tracklines: sc699_20 - sc699_26

Disc 5: SEG-Y files for tracklines: sc699_27 - sc699_31

Note: The web version of this archive does not contain the SEG-Y Trace files. These files are very large and would require extremely long download times. To obtain the complete CD-ROM archive, contact USGS Information at (888) ASK-USGS.

NOTE: Data was not collected for tracklines 7, 8 and 9.
WARNING: The acquisition system used to collect the seismic data presented in this report, may have added 6 ms to the top of each seismic trace. However, since no bathymetric data was simultaneously collected with the seismic data we have no way of proving that the added 6 ms does exist for this data set.
