Resources for Node Owners & Users
IRIS has developed a webpage to serve as a central clearinghouse for information related to nodal-style instrumentation -- including a list of community members who own their own sets of nodes.
Evolving technologies will allow the deployment of seismic arrays capable of recording well-sampled wavefields, reducing or eliminating aliasing. All bandwidths and all physical scales, from global to soils, can benefit from the recording of full wavefields, which allow measurement of otherwise undetectable signals and enable the use of full-wavefield imaging methods.
IRIS has hosted a series of online workshops to gather input from the broader seismological community about the potential scientific benefits of densely sampled full-wavefield seismic data. To record wavefields, we need practical facilities to deploy arrays at a variety of physical scales and temporal periods. The concept of the "Wavefields" effort is to produce a strong scientific case - not what we should build, but why we should build it – for every scale of application, built around the common physics of arrays and wavefields. The "Wavefields" effort is analogous to the "Science Plans" that have enunciated the goals of various community projects separate from the actual facility/program proposals.
To this end, the workshops are divided by application/scale and are intended together to be inclusive. Discussion of each topic centers on the question: "What new science would be enabled by full-wavefield seismic data?"
