About the Archive
NGDC operates the long-term archive for data from geologic samples collected during the Deep Sea Drilling Project (DSDP), Ocean Drilling Program (ODP), and from U.S. expeditions of the Integrated Ocean Drilling Program (IODP) and International Ocean Discovery Program (IODP), through an agreement with the National Science Foundation (NSF).
All non-moratorium DSDP, ODP, and IODP core data, including historic (pre-JANUS) core data from Legs 101-129 of the ODP, are available for free on-line download in tab-delimited form.
NGDC also archives high-resolution TIFF images of core photographs, 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 only available offline from NGDC, by request.

More About the Programs
The Scripps Institution of Oceanography operated the Deep Sea Drilling Project (DSDP) database from 1967 through 1983, Legs 1 through 96, at which time a copy of the prime core data were transferred to NGDC 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, and the Lamont-Doherty Earth Observatory Borehole Research Group (LDEO BRG) operated the borehole logging database. Data from Legs 101-129 of the ODP were conducted 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 all IODP programs, see the IODP web site.
Reports and CD-ROM Products
Two composite DSDP data reports published by NGDC as part of the World Data Center Report series are also available (see links at left).
CD-ROM versions of the DSDP core data for Legs 1-96
and the ODP core data for Legs 101-129 are available via the online store.
The data on these CD-ROMs may also be downloaded at no charge using the links at left.
