Summary
Abstract:
ABSTRACT: The Deep Sea Drilling Project (DSDP) operated the D/V GLOMAR CHALLENGER from 1968-1983, drilling over 1,000 holes at 624 sites worldwide. The DSDP was funded by the US National Science Foundation and several foreign countries through the Joint Oceanographic Institutions for Deep Earth Sampling (JOIDES), and was operated by the Scripps Institution of Oceanography. The DSDP data management ... group at SIO compiled a full suite of computerized marine geological and geophysical data files before they were disbanded in 1987, at which time the data files were transferred to NGDC and to the Ocean Drilling Program at Texas A&M University for distribution.In 1989, with support from, and in cooperation with, the Joint Oceanographic Institutions, Inc., U.S. Science Support Program, NGDC produced two compact discs (CDROM) containing all computerized DSDP data. In 2000, all but the logging and geophysical data were re-released as 1 CD-ROM with an HTML interface. Data are available for free online download.In 2007, the Integrated Ocean Drilling Program (IODP) transferred digital images of all core photographs and closeup core photographs in their collection to NGDC for archive. Due to their volume, these data are not available online, but are archived and available on request. The photo collections consists of 17,635 high-resolution TIFF files, volume 553.34 gigabytes.
SUPPLEMENTAL INFORMATION: The original, 1989 DSDP CDROM set included two discs and access software developed by NGDC for DOS and Macintosh platforms. Disc I contained sediment and hard rock descriptive and analytical data, documentation files, and several summary and reference files. Disc II contained downhole logging in the Schlumberger LIS format, and underway geophysical data (bathymetry, magnetics, and navigation) in the MGD77 format - the borehole and geophysical data are not included in the current metadata record - they are described elsewhere. Not all data types are included for all legs. Data files on the discs include the following: Age profile, carbon-carbonate, core depth recovery, density-porosity, gamma ray attenuation porosity evaluator (GRAPE), hard rock major and minor element geochemistry, thin section and visual descriptions of hard rock samples, interstitial water chemistry paleomagnetism of sediment and hard rock samples, paleonotology (including 22 fossil groups), smear slide descriptions, sonic velocity, vane shear, visual core descriptions, and x-ray mineralogy. Logging data in the LIS format are included for Legs 1, 4, 5, 8, 46, 58, 50, 51, 60, 61, 63-71, 74-76, 78, 80-84, 87, 89, 95, and 96. Geophysical data consist of bathymetry, magnetics, and navigation for legs 4-96 (not all data types are available for all legs).Note: on Feb 22, 2006 latitude/longitude information was updated for LEG 001 Hole 2 to correct an error that was present since the files were first transferred to NGDC. ODP personnel certified the correction.
