|Worldwide Marine Seismic Reflection Profiles
|NGDC 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. However, to obtain data
as a result of this search please contact NGDC. These data were collected mainly by
US Geological Survey and various geophysical companies.
