FDSN Working Group V on Portable Instrumentation
The Working Group on Portable Instrumentation was formed
at the 2003 meeting of the FDSN in Sapporo, Japan. This
working group will coordinate the activities of the various
groups around the globe that deploy portable instruments
in field experiments.
Areas of interest to the working group include:
- promote the use of uniform data archive formats and
- promotion of open access to data after an exclusive
- promote best practice among FDSN members.
- develop and maintain an inventory of available equipment
on the FDSN website.
- maintain an archive of metadata about past, current
and planned experiments through links from the FDSN website.
- maintain a list of links to ocean bottom seismometer
The current membership of WG V:
Alex Brisbourne (Chair) - SEIS-UK

Jim Lyons - GSC, Canada
Christa von Hillebrandt, Puerto Rice SN
Jean-Claude Le Pine IPGP/Geoscope

Recommended Data Format
FDSN recommend the use of full SEED or miniseed with dataless
seed volumes as the preferred archive data format. This format
is already in use across the seismological community and
is the preferred format of the large data centres.
- A full
SEED manual is available from the IRIS website.
- Utilities for reading (rdseed), writing (PDCC) and evaluating
(evalresp) SEED volumes are also available via the IRIS
website software listing.
- Utilities for manipulating miniseed data are available
in the PASSCAL
software package, e.g. qmerge, mseedmod, mseedhdr.
Recommended Data Access Criteria
FDSN encourage all users of portable instrumentation to make
their data available to the wider community as soon as
possible. All users should archive their data with a data
centre which allows rapid access to the global community.
It is common practise for groups to release their data
by default after a fixed period, of 0-3 years.
FDSN Network Codes
FDSN recommends that all temporary deployments are assigned
an FDSN network code via the online
These codes provide uniqueness to seismological data streams.
By using these codes for all future experiments, a readily
accessible database of projects undertaken by equipment pools
can easily be maintained. Even if data are not archived with
a data centre, the database would allow data users to find
any potential collaborators who have been working in similar
