Abstract

Recent advances in seismic data-Acquisition technology paired with an increasing interest from the academic passive source seismological community have opened up new scientific targets and imaging possibilities, often referred to as Large-N experiments (large number of instruments). The success of these and other deployments has motivated individual researchers, as well as the larger seismological community, to invest in the next generation of nodal geophones. Although the new instruments have battery life and bandwidth limitations compared to broadband instruments, the relatively low deployment and procurement cost of these new nodal geophones provides an additional novel tool for researchers. Here, we explore the viability of using autonomous three-component nodal geophones to calculate teleseismic Ps receiver functions by comparison of co-located broadband stations and highlight some potential advantages with a dense nodal array deployed around the Upper Geyser basin in Yellowstone National Park. Two key findings from this example include (1) very dense nodal arrays can be used to image small-scale features in the shallow crust that typical broadband station spacing would alias, and (2) nodal arrays with a larger footprint could be used to image deeper features with greater or equal detail as typical broadband deployments but at a reduced deployment cost.

Fieldwork for this project was partially supported by the Brinson Foundation and the Carrico Fund. The content of this article benefited from several informal conversations with Jonathan R. Delph and Keith D. Koper. Waveforms were preprocessed using the Seismic Analysis Code (SAC) software (Goldstein et al., 2003; Goldstein and Snoke, 2005), and all figures presented were generated using the Generic Mapping Tool (GMT) software (Wessel et al., 2013). The digital elevation model (DEM) in Figure 10a is based on services provided to the Plate Boundary Observatory (PBO) by National Center for Airborne Laser Mapping (NCALM; http://www.ncalm.org, last accessed May 2017). The PBO is operated by University NAVstar COnsortium (UNAVCO) for EarthScope (http://www.earthscope.org, last accessed May 2017) and supported by the NSF (Number EAR-0350028 and EAR-0732947). The authors would specifically like to acknowledge Brandon Schmandt for proposing the nodal geophone deployment near Station NLU, Andy Trow for deploying the nodal stations as part of an undergraduate research project (UROP) supported by the University of Utah, Jamie Farrell for organizing the Old Faithful nodal deployment, and all involved with the Incorporated Research Institutions for Seismology (IRIS) Community Wavefield Experiment in Oklahoma. The authors would like to thank all of the faculty, Postdocs, and other students and staff responsible for deploying and maintaining the seismic stations used in this study. Finally, the authors would like to acknowledge the contribution of two anonymous reviewers and two journal editors, whose comments benefited the content of this article.
