IRIS is excited to announce a Full Wavefield Demonstration Experiment that will take place in 2016. The goal of this experiment is to allow the seismological community to gain experience with new acquisition techniques for obtaining full wavefield observations using a range of instrumentation at multiple spatial and temporal scales. The goal of these new techniques is to increase resolution and reduce aliasing while optimizing instrument usage (i.e. using the right instruments and geometry for the appropriate part of the spectrum). The experiment will utilize next-generation 3-component nodal-type instruments and our existing pool of broad, intermediate and short period instruments to demonstrate new capabilities and modes of operation, and to collect an open wavefield dataset for the community to explore and utilize in new ways.
