IEDA hosts diverse data!¤ IEDA is a data facility that hosts observational solid earth data and
tools from the marine, terrestrial, and polar environments. !
¤ Multiple diverse data systems that were developed independently, serving both !¤ sensor data from large collaborative cruise programs !¤ sample-based measurements from unique analytical laboratories !
¤ IEDA data systems enable the data to be discovered and reused.!

IEDA needs persistent identifiers!
Persistent identifiers help IEDA achieve greater…!
¤ Accessibility: by navigating diverse but related data in the IEDA systems!
¤ Reliability: by maintaining links between IEDA and outside systems that persist through time!
¤ Citability: by enabling proper attribution to research with long-lived, citable, identifiers!

What are the IEDA identifiers?!
¤ IEDA Maintained IDs!¤ People!¤ Samples!¤ Datasets / Datafiles / Software!¤ Cruises/Expeditions!
¤ Externally maintained IDs, used in IEDA systems!¤ Publications!¤ Funding Awards!¤ Platform IDs (ICES)!
¤ Cruise IDs (R2R)!
¤ Organization IDs (IANA)!
¤ Country, State, Language codes (ISO)!

Samples – IGSN!
¤ The International Geo Sample Number !¤ uniquely identifies physical samples!¤ links to detailed metadata profiles !¤ ensures unambiguous citation of samples in the literature !
¤ Governed by IGSN e.V., distributed by SESAR!
¤ Syntax and implementation is guided by the IGSN e.V. and user community!
