The Deep Sea Drilling Project (DSDP) operated the D/V GLOMAR CHALLENGER from 1968-1983,
drilling 1,112 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. |
