|Downhole Logging Data from the Deep Sea Drilling Project
|Digital downhole wire-line logging data from the Deep Sea Drilling Project (DSDP)
previously available from NGDC on CD-ROM are now available from the Borehole Research
Group of the Lamont-Doherty Earth Observatory online. DSDP logs were generated from
1967-1983, DSDP logs were produced under contract to the Scripps Institution of Oceanography,
Science Operator for the DSDP. Parameters measured may include conductivity, bulk
density, porosity, resistivity, grain density, sonic ratio, and other parameters.
Parameters vary from hole to hole and cruise to cruise. The DSDP log data are available
on a CD-ROM with accompanying software. Data are primarily in the Schlumberger LIS
format. Some DSDP logs are in the Gearheart-Owen format, and logs for one site are
in ASCII form. All DSDP logs have been translated into Schlumberger LIS format on
the CD-ROM. Additional logs are available only in analog (microfilm) form. Complete
documentation for the LIS format was provided on the original CD-ROM.
