        abstract:  Dr. Christopher Jenkins of the University of Colorado Institute for Arctic and Alpine Research (INSTAAR), produced this data hypercube derived from the prime data (exclusive of G.R.A.P.E. and logging data) of the Deep Sea Drilling Project (DSDP). The Deep-Sea Drilling Project legacy data on the lithologies and physical properties of core recoveries is reprocessed into a uniformly formatted, integrated dataset which can be worked on in a wide range of software applications for query, analysis, mapping and visualization. The goal is to create a dataset which is able to be used efficiently across many science disciplines, especially in the fields of global change, ocean management and earth sciences research. The hypercube data model allows scientists and others to easily comprehend and work with the data layout and content. The integration has employed methods of standardization, linguistic parsing, error trapping, uncertainty analysis, and presentation that have developed and been validated over a decade of use in dbSEABED, for marine ecology, resources, engineering, research and survey. Nevertheless integration of the DSDP dataset has been challenging, not all the DSDP data could be treated successfully.
        purpose:  Scientific Research
        credit:  The DSDP data were prepared by Dr. Christopher Jenkins of the Institute for Arctic and Alpine Research with funding from the Consortium for Ocean Leadership.

            descriptor:  Author description - Geological time in the original DSDP data was given in terms of period, stage, and zone biostratigraphic and chronostratigraphic terms. Only rarely were absolute isotopic or paleomagnetic ages attached to materials. Unfortunately, but inevitably, the geologic time scales in use evolved during DSDP, and on-board age determinations were interim. Lazarus et al. (1995) developed age-depth models for 88 of the drilled holes according to one time scale and those models are refined, extended and served now through Chronos (2007). The revisions of time scales and time terms were not propagated systematically through the DSDP data, though some post-cruise datings were merged in during creation of the CDROM compilation. We have taken the CDROM age determinations such as Early Oligocene and applied the International Stratigraphic Commission (ICS) timescale (Gradstein et al. 2004) to those names. This is a simplistic approach, admittedly, but we look to qualified geochronologists to replace these ages with better calibrated values in the future. The assessed scale of error in the method is of the order of less than 1My (exceptionally up to 4My) to judge from successive revisions of stage absolute ages (Gradstein et al. 2004). The method of parsing the age terms was as follows. Age values are encountered in the CDROM, AGEPROF or PALEO, lines, given usually as a stage name, perhaps with a division like (early). In the dbSEABED dictionary the chronological unit names are assigned absolute values (e.g. entry, rupeln,Rupelian Stage,date,28.4,33.9,0.1, 0.1) of youngest, oldest, youngest uncertainty, oldest uncertainty. The unit is millions of years (my). The parser uses the youngest/oldest limits to create a code like (28.4y:o33.9) (with the uncertainties e.g., 28.4[0.1]y:o33.9[0.1]). An analysed age such as K-Ar dating will appear in EXT (e.g., 0.0023[0.0001]y:o), a biostratigraphic age in PRS. Where an age range is given, such as "upper_oligocene to lower_miocene" the two age ranges are combined, giving in this case the result (15.97t:b28.4). So that data can be plotted to GIS, the code is transferred to a single central value in the preparation of the DSD_...n and Shapefile filesets. So that all samples have a time coordinate, just as they have a geographic coordinate, an age-depth index was built and was used to spread the age values throughout entire the DSD_...n and Shapefile filesets. Undated samples took the age of the sample next above.

                attributeType: (unknown)
            descriptor:  Author description - The vertical datums used during data collection and archiving have been an impediment to creating a global analysable structure from ocean lithologic data. In this project we retain the original values, but the prime vertical coordinate is altitude relative to present sealevel. By using altitudes we keep the proper handedness of the data. Of course, sealevel is an inexact datum, but the variations are unlikely to be an issue except for closed-spaced or re-occupied DSDP holes.

            descriptor:  Author description - A feature of dbSEABED outputs is the DataType or Audit Code. In first-level outputs it holds record of the data themes that contribute to an output record, for instance LTH.COL.GTC for lithology, colour, geotechnical. It will be different for extracted and parsed outputs. On merging these, as is done for the ONE and WWD output levels, DataType records whether a parameter is extracted (i.e., analysed, numeric) or parsed (i.e., descriptive, word-based), or specially calculated (estimated). A sequence like PPPxPPxxxxPEEEPExxxPE shows the EXT, PRS, CLC origins of the next 20 parameters, from [Gravel] to [GeolAge].

            sequenceIdentifier:
              MemberName:
                aName:  sample key
                attributeType: (unknown)
            descriptor:  Author description - We attach a sequential number - Sample Key - to each observed unit, segregation, sample, phase or fraction: in short to each different analysed material. Some samples are subject to many different analyses, and then one key applies to all those analyses. High value is obtained from this because it allows inter-parameter comparisons. When an observation is made at different scales, such as a visual description versus a smear slide, that counts as different material and key. A code for the DSDP Leg, Site, Hole, Core and Section is given for each material (e.g., DSDP:23:310:A:15:6) and can be used in relational databases. Other details on the sectioning and labelling of the core materials is provided by NOAA (2000).
