IGSN: The International Geo Sample Number (DFG Roundtable)

  1. 1. 1 www.igsn.org February 25, 2016 DFG Rundgespräch Geochemical Databases
  2. 2. Relevance of Samples  Samples are the source of observational data and measurements across disciplines.  Samples provide irreplaceable evidence of long-term historical trends.  Samples serve as standards or references.  Samples record unique events in history and/or unique opportunities to collect specimens (e.g. moon rocks). February 25, 2016 DFG Rundgespräch Geochemical Databases 2
  3. 3. Scientific Collections: Policy February 25, 2016 DFG Rundgespräch Geochemical Databases 3 “Improving the Management of and Access to Scientific Collections”
  4. 4. Geosamples Status : Preservation  Many samples are not archived and curated due to lack of funds, space, & required effort. 4 February 25, 2016 DFG Rundgespräch Geochemical Databases
  5. 5. Geosamples Status: Access  Many samples and collections are not ‘online’.  Repositories lack resources & expertise to develop & maintain digital collection catalogs.  Samples often only described in publications.  Existing online catalogs are not connected or federated.  No easy way to search for samples. 5 February 25, 2016 DFG Rundgespräch Geochemical Databases
  6. 6. Geosamples Status: Non-unique ID’s February 25, 2016 6 The EarthChem Portal shows 75 publications with geochemical data referenced to a sample with the name M1 (or M-1). (www.earthchem.org) Names of dredge sample 3 of the Amphitrite cruise (PetDB database, www.petdb.org) “The key measurement was the one backarc basalt called "PPTUW”... Subsequent efforts to confirm the observation ran into problems. The apparently-same sample was variously called PPTU, PPTUW/5, PPTUW-1, and TVZ19 in four other papers. None of those papers gave its latitude and longitude…!” (J. Gill and E. Todd, personal communication 2013, related to IEDA data rescue effort) DFG Rundgespräch Geochemical Databases
  7. 7. Geosamples: New Opportunities in CI  Online sample catalogs can dramatically improve discovery and access of collections for broad audiences.  Software tools can support and streamline collection management.  Interoperability provides unprecedented capabilities to  Link data, samples, and publications  Link all data acquired on a single sample & subsamples  Integrate sample-based data with other data types February 25, 2016 DFG Rundgespräch Geochemical Databases 7
  8. 8. Imagine the Possibilities …  Find all publications that mention a specific sample  Find all data for that sample in easily usable, electronic format  Find other samples with similar properties  geospatial  temporal  compositional  Find the sample and contact its owner February 25, 2016 DFG Rundgespräch Geochemical Databases 8
  9. 9. What is happening:  IGSN (International GeoSample Number)  Registry of unique sample identifiers  Distributed system of metadata catalogs  iSamples (EarthCube Research Coordination Network)  Community initiative to build the Internet of Samples in the Earth Sciences  DESC (Digital Environment for Sample Curation)  Shared cyberinfrastructure for collections management  Planning effort funded by NSF/OCI  GRSciColl  International effort to build registry of collections  hosted by the Smithsonian Institution (D. Schindel, E. Graham)  CODATA Task Group  Physical Objects in Cyberinfrastructure February 25, 2016 DFG Rundgespräch Geochemical Databases 9
  10. 10. IGSN: International GeoSample Number  provide identifiers that are guaranteed to be unique via a centralized control mechanism  catalog and preserve sample metadata through user- based registration
  11. 11. Why we need PIDs for samples?  Discovery & Access for Re-use and Reproducibility  Unambiguously reference a sample when reporting data.  Locate and link to a sample’s ‘virtual representation’.  Sample Citation  Give credit to sample collectors for the intellectual effort and resources they put into collection, preparation, and curation of the sample.  Data Integration  Link data that are acquired on a single sample in different labs and over long periods of time and published in different articles.  Sample Management  Track samples & sub-samples through their life cycle (from field to lab to repository) 11 February 25, 2016 DFG Rundgespräch Geochemical Databases
  12. 12. IGSN History  Developed at LDEO/CIESIN  NSF grants in 2004 and 2006  System for Earth Sample Registration  International governance established in 2011  15 members in USA, Australia, Europe, Asia  Central Catalog of registration metadata at GFZ Potsdam (Handle service)  Central Catalog of descriptive metadata at LDEO (Managing Office) February 25, 2016 DFG Rundgespräch Geochemical Databases 12
  13. 13. IGSN Adoption: Sample Repositories February 25, 2016 DFG Rundgespräch Geochemical Databases 13

  15. 15. IGSN Adoption: Publishers COPDESS Statement of Commitment February 25, 2016 DFG Rundgespräch Geochemical Databases 15
  16. 16. IGSN Adoption: Publishers 16 “… AGU Publications also strongly encourages use of other identifiers in our journal papers. International Geo Sample Numbers (IGSNs) uniquely identify items, such as a rock sample, a piece of coral, or a vial of water taken from the natural environment, and provide important, consistent information about these samples. Registering samples and including the IGSN in papers helps secure provenance information but most importantly connects common samples across multiple studies in the literature. IGSNs also will help you keep track of your samples. These identifiers can be reserved before a field season or assigned afterward.” Hanson, B. (2016), AGU opens its journals to author identifiers, Eos, 97, doi:10.1029/2016EO043183. Published on 7 January 2016. February 25, 2016DFG Rundgespräch Geochemical Databases

What objects get an IGSN?  Individual specimens  Categorized by material (rock, mineral, soil, fluid, etc.)  Subsamples (linked to ‘parent sample’)  Thin section, grain size fraction, mineral/fossil separate, etc.  ‘Parent objects’ such as cores, dredges, CTDs  Individual samples of these are ‘children’  Locations such as drill-holes, wells, soil pits, sections (‘sampling features’) 20 February 25, 2016 DFG Rundgespräch Geochemical Databases
