Dear Colleagues:

IRIS is pleased to announce that the data collected during the Community Wavefields Demonstration Experiment are now fully archived and available at the IRIS DMC. They data can be accessed via standard DMC tools, and you can view the metadata here:

In early 2016 IRIS solicited concepts for a community wavefield experiment to demonstrate the feasibility and methods of recording the full seismic wavefield. Many excellent concepts were received, and the selected design was a hybrid of several ideas for experiments in Oklahoma. With the participation of the community-based PI team and numerous community members, the experiment was deployed near Enid, Oklahoma in June of 2016. The experiment made use of new 3-component nodal sensors to deploy 3 seismic lines and a 7-layer nested gradiometer. In addition, 18 broadband stations were deployed in a “Golay” array design, along with 9 infrasound sensors co-located with 9 of the broadband stations. In total, the experiment spanned a roughly 3 x 12 km area with about 400 instruments.

The nodes were deployed for 30 days from late June to late July, and the broadband and infrasound stations were deployed for approximately 5 months, from late June to mid November.

For more information on the experiment design, instrumentation, and participants, please visit IRIS’ wavefields page ( and click on the “Experiment Overview and Summary” link.

A hearty thanks to the many volunteers (students, postdocs, faculty, and others) as well as staff from the IRIS/PASSCAL Instrument Center and the IRIS DMC for helping to make this dataset available to the community.

A student short course organized around this dataset is planned for summer 2017. If you or your students might be interested in applying for this short course, please watch your email for an announcement in the next few months.
