The Index to Marine and Lacustrine Geological Samples
Beta SKOS Controlled Vocabularies (no change since January 2012)
This service may disappear or URLs may change, this is only a demonstration.
The Index to Marine and Lacustrine Geological Samples database (also known as the Core Curators'
database) was designed by the Curators of Marine Geological Samples group in
cooperation with the National Geophysical Data Center. NGDC has maintained the database on behalf of the Curators' group since 1977.
The minimum information included for each core, grab, dredge, or drill sample is: ship, cruise, sample id, and latitude/longitude. The combination of ship, cruise, sample id, and device is unique for each sample. Ship may have a value of unknown, as may device.
Database contents and vocabularies/parameters have been augmented and modified many times over the years, expecially the lithologic classification system. Notable additions to the database include IGSN number, links to corresponding information at participating insitutions, R2R, the USGS InfoBank, SESAR, the MGDS, and the SIO Explorer.
For complete information about entities and attributes of the Index database, please see the FGDC Metadata Record. Metadata for the database are in the process of being migrated to the ISO 19115-2 standard. Also see coding information and diagrams.
