update Definition (The IRIS Global Seismographic Network (GSN) is one of the four major components
of the IRIS Consortium. The goal of the GSN is to deploy 128 permanent seismic
recording stations uniformly over the earth's surface.

Stations:

As of 2003 the IRIS GSN was made up of over 128 stations with affiliations to
USGS, UCSD/IDA, GEOFON, Pacific21, NCDSN, GEOSCOPE, MedNet, BGR, BFO, USNSN,
BDSN, TriNet, AFTAC and several other national and international networks.
Eight new stations are planned for completion in 2003-2005.

The IRIS GSN stations continuously record seismic data from very broad band
seismometers at 20 samples per second, and to provide for high-frequency (40
sps) and strong-motion (1 and 100 sps) sensors where scientifically warranted.
It is also the goal of the GSN to provide for real-time access to its data via
Internet or satellite. Over 75% of the IRIS GSN stations meet this goal.);
