Hello All,

This is a simple question (I hope) but I have seen different answers, so
would like to verify.

In the ISC seismic station registry, it looks like a seismic station
name has to be unique (without its network code). However, in the FDSN
definition it looks like the as long as the station name is unique
within a network code it can be used. From,
https://iris-edu.github.io/xseed-specification/docs/xFDSNSourceIdentifiers-DRAFT20190520.pdf

Network code​: Uniquely identifies the owner and network operator
responsible for the data. This
identifier is assigned by the FDSN. Must be between 1 and 8 characters.

Station code​: Uniquely identifies a station within a network. Must be
between 1 and 8 characters.


My example is a new seismic station installed in Dusheti, Georgia
(network code "GO").  Station name "DSHT".   We would like to archive
this at the IRIS DMC. However, in the ISC registry there is already a
station name of "DSHT"
http://www.isc.ac.uk/cgi-bin/stations?stacode=DSHT located somewhere
else (although apparently not active any more).

Thanks for any clarification.

    Hi all,

    I do not recall an official FDSN requirement regarding conformance with the International Registry @ ISC. In the 2007 WG I report the following statement is included and I believe is the general consensus of members:

    "FDSN encourages each regional coordinator to register the stations to ISC"

    Also note that the FDSN Source Identifier proposal has been accepted and is published here:

    http://docs.fdsn.org/projects/source-identifiers/en/v1.0/

    Within the accepted specification including this in the Station Code definition:

    "Station code: Uniquely identifies a station within a network. Station codes may be registered with the International Registry of Seismograph Stations http://www.isc.ac.uk/registries/. Must be between 1 and 8 characters. Otherwise, these may be whatever the operator wishes."

    regards,
    Chad

      Dear All,

      As far as I know, the ISC plans to adopt the FDSN station naming convention which is reflected in the new ISF2 format (yet to be introduced
      at the ISC). At least that was the plan several years ago. BTW, what makes a station id unique in the FDSN convention is the entire fdsn code
      (net.sta.chan.location) plus the on and offdates because the network codes are not unique either; the temporary network codes get often
      recycled. You need to register your stations at the ISC if you wanted to contribute picks/events to the ISC.
      I also cc-d Dmitry Storchak if he wanted to put in his sixpence.

      Cheers,
      Istvan

          Dear all,

          I think it is time to start associating station codes in the ISC registry
          with network codes. Up to know ISC station registration does not require
          any FDSN network code declaration in the web form. So it seems that FDSN
          registers networks and ISC registers stations and these two registries are
          not connected at all.

          All the best,
