PASSCAL Instrument Center and IRIS DMC “mint” Digital Object Identifiers for all IRIS PASSCAL Experiments

Recently the International Federation of Digital Seismograph Networks (FDSN) published an article in EOS (08Oct2015) recommending that permanent networks and temporary seismic experiments have a Digital Object Identifier (DOI) available. This DOI can help insure that researchers using their data in a publication can attribute seismic networks and experiments. IRIS, working with several partners in the FDSN, developed a standard method through which the Seismic Network DOIs should be constructed. Information about the FDSN DOI effort can be found at .

At the present time several hundred DOIs consistent with the FDSN guidelines have been minted. (see As of November 10, 2015 69 permanent seismic networks and 325 temporary seismic experiments have had FDSN DOIs minted. The large number of temporary seismic experiments are a result of an automated approach to minting DOIs for all PASSCAL temporary experiments that had data at the DMC. Using a summary of all such experiments generated by the PASSCAL Instrument Center, the IRIS DMC minted these DOIs in a bulk manner.

One such example of a DOI is that for the Brandon Schmandt iMush experiment, network code 1D the year 2014. The DOI for this experiment, following FDSN conventions is doi:10.7914/SN/1D_2014. On the FDSN web pages the landing page for this experiment can be found at

The two figures show information that can be found at the above URL. The first figure shows information about the experiment including the DOI and the citation. The second figure shows the locations of stations in the experiment on a map followed by a tabular listing of stations and their locations.

Similar information can be found for all PASSCAL temporary experiments that have their data at the DMC and PIs should let users of their data know that the data can now be cited with an FDSN compliant DOI.
