Subbottom Profile data files: Subbottom Profiler

NCEI maintains a large volume of both analog and digital seismic reflection data. Currently only a limited number of lines are available online. Digital data include SEGY files and scanned images of the full-scale section as well as shot point navigation. Additional digital seismic reflection data are available on request and can be searched for (along with other underway geophysical data) using GEODAS. Analog data are available on microfilm or as either paper/Mylar full-scale sections. A search for seismic reflection data using GEODAS will determine what data exist in a region.

This file contains US Geological Survey Open File Reports for Marine Seismic-Reflection data. The majority of these data are available on mylar/black line full-size sections. Lines may be obtained for the entire Open File Report or by individual line. Shot-point navigation maps usually accompany the sections and digital navigation is also available.

This data set contains single channel seismic reflection profiles as provided to NGDC by Lamont Doherty Earh Observatory (LDEO). The profiles were originally provided as 8x10 negatives, but were scanned and now available as digital images. Images were scanned at 400 dpi using 8-bit grayscale and are in jpg format.

These data are stacked multichannel marine seismic reflection data from thirteen lines recorded during 1983 off Wilkes Island, Antarctica, by the Japan National Oil Corporation. The following data types are included for each line: computer display images, location maps, and the digital seismic data. Software is provided to view the images, to plot selected portions of the data to the screen, and to convert the data into SEG-Y formation. The CD-ROM was produced in accordance with the ISO 9660 Standard. The display software runs only under DOS. All text files are in ASCII format.

These data are stacked multichannel marine seismic reflection data from six lines recorded during 1988 in the Ross Sea, Antarctica, by the Bundesanstalt fur Geowissenschaften und Rohstoffe (BGR). under the auspices of ItaliAntartide, the Italian National Research Program in Antarctica. The following data types are included for each line: computer display images, location maps, and the digital seismic data. Software is provided to view the images, to plot selected portions of the data to the screen, and to convert the data into SEG-Y formation.

These data are stacked multichannel marine seismic reflection data from four lines recorded during 1980 in the Ross Sea, Antarctica, by the Bundesanstalt fur Geowissenschaften und Rohstoffe (BGR). The following data types are included for each line: computer display images, location maps, and the digital seismic data. Software is provided to view the images, to plot selected portions of the data to the screen, and to convert the data into SEG-Y formation. The CD-ROM was produced in accordance with the ISO 9660 Standard. The display software runs only under DOS.

These data are stacked multichannel marine seismic reflection data from seven lines recorded during 1980 in the Ross Sea, Antarctica, by the Bundesanstalt fur Geowissenschaften und Rohstoffe (BGR). The following data types are included for each line: computer display images, location maps, and the digital seismic data. Software is provided to view the images, to plot selected portions of the data to the screen, and to convert the data into SEG-Y formation. The CD-ROM was produced in accordance with the ISO 9660 Standard. The display software runs only under DOS.

These data are stacked multichannel marine seismic reflection data from eleven lines recorded during 1980 in the Ross Sea, Antarctica, by the Bundesanstalt fur Geowissenschaften und Rohstoffe (BGR). The following data types are included for each line: computer display images, location maps, and the digital seismic data. Software is provided to view the images, to plot selected portions of the data to the screen, and to convert the data into SEG-Y formation. The CD-ROM was produced in accordance with the ISO 9660 Standard. The display software runs only under DOS.
