Proposal for new StationXML standards and miniSEED + Source Identifiers documentation

[Wayne Crawford]

Dear Working Group 2 members,

Please find attached a document on marine seismology data/metadata standards, based on the work of WG5’s Action Committee on Marine seismology data

from 2023-2025, and discussed with WGs 2 and 5 during the 2025 Lisbon FDSN Meeting.

Section 2 contains specific requests for changes to FDSN standards or documentation:

• Section 2.1: Additions to “Source Identifiers” documentation,  for Seismometer channel subsource codes
• Section 2.2: New StationXML elements:
• 2.2.1: <ClockDrift>
• 2.2.2: <Leveler>
• Section 2.3:  Additions to “miniSEED” documentation, for clock drift correction, unmeasured clock drift where significant drift is expected, and leap-second corrections.

We hope that you find these requested changes pertinent and implementable.  If you judge any of them to be inappropriate for official standards or documentation, please tell us.

Best regards

The FDSN Working Group 5 Action Group on marine seismology standards

Dear Wayne, all,

Do you popose to add these XML elements to a new version (e.g. 1.3) of stationXML by defining them in the stationXML's XSD, or shall they be defined in their own namespace and added to current stationXML 1.2 documents?

Thanks, and best regards

Philipp
