Project IDA: A decade in review

Project IDA (International Deployment of Accelerometers) is a global digital seismic network that collects data for low-frequency seismology. This article reviews the operation of the network and scientific results based on its data in the decade since the first station was installed in 1975. Particular attention is given to some of the lessons to be drawn from operational experience. Upgrades of the IDA network, incuding three-component sensors and higher sample rates, are described briefly.
