International Ocean Drilling Data Archive

Additional Information

All non-moratorium DSDP, ODP, and IODP data, including historic (pre-JANUS) core data from Legs 101-129 of the ODP, are available for download in tab-delimited form.

High-resolution TIFF images of core photographs are also archived, including close-ups and microphotographs of thin sections and smear slides. Due to their large volume and their availability in PDF form on the IODP web site, these images are available only offline by request.

The Scripps Institution of Oceanography operated the Deep Sea Drilling Project (DSDP) database from 1967 through 1983; Legs 1 through 96.  A copy of the prime core data was transferred to NOAA's National Geophysical Data Center, now NCEI, for archive and distribution.

Texas A & M University (TAMU) operated the Ocean Drilling Program (ODP) core database from 1984 through 2002; Legs 101 through 210. The Lamont-Doherty Earth Observatory Borehole Research Group (LDEO BRG) operated the borehole logging database. Data from Legs 101-129 of the ODP were collected before the JANUS database was built. Not all of the data, or data types, from these legs were entered into the JANUS database.

Beginning in 2003, the Integrated Ocean Drilling Program (IODP) replaced the ODP. TAMU continued operation of the U.S. core database, and LDEO BRG continued operation of the U.S. borehole database. Beginning with expedition 317, the JANUS core database was replaced by the LIMS database.

In 2013, the Integrated Ocean Drilling Program was replaced by the International Ocean Discovery Program (IODP). The U.S. core and borehole databases continue to be operated by TAMU and LDEO BRG, respectively. For complete information on the DSDP, ODP, and IODP programs, see the IODP web site.
