This is a testing app for exploring in the open various search interfaces on top of the linked open data cloud hosted as part of data.oceandrilling.org. Please note these are experiments and not intended for use in accessing IODP-USIO data. The coverage of data at this site is not complete. Please visit http://data.oceandrilling.org/tools.html for links to production search resources.
Free text searching attempts to match text both to vocabulary concepts (coming soon) and also to individual resources. It matches only on the literal value of the object triple at this time. Some testing with Siren has been done also, but is not currently available here. (soon)
This site serves as a sandbox for ideas related to data access. There is also a page documenting existing search resources at Texas A&M and LDEO for parameter based data searches. (link to that page)
Ocean drilling samples are recovered in cores, long tubes of material collected while drilling beneath the sea floor. Specific terminology is used to precisely describe the location of a sample taken in a core.
Leg, Expedition – During the history of ocean drilling, the science has been carried out in segments called legs during DSDP and ODP and expeditions during IODP.
Site, Hole – A site is a location at which drilling is conducted. Drill sites are numbered consecutively starting with the first drilled by the Glomar Challenger in 1968. If more than one hole is drilled at a site, each hole receives a different letter suffix (A, B, C, etc).
Core – Each cored interval is usually 9.5 to 9.6 meters and 6 cm in diameter.
Section – A core is cut into sections 1.5 meters long, numbered from the top of the core.
Interval – A sample from a core is designated by distance in centimeters from the top of the section to the top and bottom of the sample removed.
A sample identification number includes: leg, site, hole, core number, core type, section number, and interval in centimeters measured from the top of section. For example, “210-1276A-3R-3, 80–85 cm” is a sample from the interval 80 to 85 cm below the top of Section 3, Core 3R of Hole 1276A during Leg 210. All ODP core identifiers indicate core type (R = rotary core barrel, H = advanced piston corer, X = extended core barrel, and W = wash core).
Cored intervals can also be described in meters below sea floor (mbsf). The mbsf depth of a sample is determined by adding the depth of the sample below the section top and the lengths of all higher sections in the core to the core-top datum measured with the drill string.
