Classifying Worldwide Standardized Seismograph Network records using a simple convolution neural network
The U.S. Geological Survey (USGS) maintains an archive of 189,180 digitized scans of analog seismic records from the World‐Wide Standardized Seismograph Network (WWSSN). Although these scans have been made public, the archive is too large to manually review, and few researchers have utilized large numbers of these records. To facilitate further research using this historical dataset, we develop aAuthorsNagle Nagle-McNaughton, Adam T. Ringler, Robert E. Anthony, Alexis Casondra Bianca Alejandro, David C. Wilson, Justin Thomas WilgusImproved resolution across the Global Seismographic Network: A new era in low-frequency seismology
The Global Seismographic Network (GSN)—a global network of ≈150 very broadband stations—is used by researchers to study the free oscillations of the Earth (≈0.3–10 mHz) following large earthquakes. Normal‐mode observations can provide information about the radial density and anisotropic velocity structure of the Earth (including near the core–mantle boundary), but only when signal‐to‐noise ratiosAuthorsAdam T. Ringler, Robert E. Anthony, P. Thompson Davis, Carl Ebeling, K. Hafner, R. Mellors, S. Schneider, David C. WilsonSeismic background noise levels across the continental United States from USArray Transportable Array: The influence of geology and geography
Since 2004, the most complete estimate of background noise levels across the continental U.S. was attained using 61 broadband seismic stations to calculate power spectral density (PSD) probability density functions. To improve seismic noise estimates across the U.S., we examine vertical component seismic data from the EarthScope USArray Transportable Array seismic network that rolled across the U.AuthorsRobert E. Anthony, Adam T. Ringler, David C. WilsonLocal variations in broadband sensor installations: Orientations, sensitivities, and noise levels
As seismologists continue to place more stringent demands on data quality, accurately described metadata are becoming increasingly important. In order to better constrain the orientation and sensitivities of seismometers deployed in U.S. Geological Survey networks, the Albuquerque Seismological Laboratory (ASL) has recently begun identifying true north with a fiber optic gyroscope (FOG) and has deAuthorsAdam T. Ringler, Robert E. AnthonyAn evaluation of the timing accuracy of global and regional seismic stations and networks
Clock accuracy is a basic parameter of any seismic station and has become increasingly important for seismology as the community seeks to refine structures and dynamic processes of the Earth. In this study, we measure the arrival time differences of moderate repeating earthquakes with magnitude 5.0–5.9 in the time range of 1991–2017 at the same seismic stations by cross‐correlating their highly siAuthorsYing Yang, Xiaodong Song, Adam T. RinglerModeling seismic network detection thresholds using production picking algorithms
Estimating the detection threshold of a seismic network (the minimum magnitude earthquake that can be reliably located) is a critical part of network design and can drive network maintenance efforts. The ability of a station to detect an earthquake is often estimated by assuming the spectral amplitude for an earthquake of a given size, assuming an attenuation relationship, and comparing the predicAuthorsDavid C. Wilson, Emily Wolin, William L. Yeck, Robert E. Anthony, Adam T. RinglerModelling tilt noise caused by atmospheric processes at long periods for several horizontal seismometers at BFO—A reprise
Tilting of the ground due to loading by the variable atmosphere is known to corrupt very long period horizontal seismic records (below 10 mHz) even at the quietest stations. At BFO (Black Forest Observatory, SW-Germany), the opportunity arose to study these disturbances on a variety of simultaneously operated state-of-the-art broad-band sensors.

A gallery of compromised seismic signals
Seismic instruments are highly sensitive and capable of recording a large range of different Earth signals. The high sensitivity of these instruments also makes them prone to various failures. Although many failures are very obvious, such as a dead channel, there are other more subtle failures that easily go unnoticed by both network operators and data users. This work documents several differentAuthorsAdam T. Ringler, David B. Mason, G. Laske, Tyler Storm, M. TempletonSix decades of seismology at South Pole, Antarctica: Current limitations and future opportunities to facilitate new geophysical observations
Seismograms from the South Pole have been important for seismological observations for over six decades by providing (until 2007) the only continuous seismic records from the interior of the Antarctic continent. The South Pole, Antarctica station has undergone many updates over the years, including conversion to a digital recording station as part of the Global Seismographic Network (GSN) in 1991AuthorsRobert E. Anthony, Adam T. Ringler, M. DuVernois, K. Anderson, David C. WilsonA review of timing accuracy across the Global Seismographic Network
The accuracy of timing across a seismic network is important for locating earthquakes as well as studies that use phase‐arrival information (e.g., tomography). The Global Seismographic Network (GSN) was designed with the goal of having reported timing be better than 10 ms. In this work, we provide a brief overview of how timing is kept across the GSN and discuss how clock‐quality metrics are embedAuthorsAdam T. Ringler, Robert E. Anthony, David C. Wilson, D.

The Global Seismographic Network (GSN) is a multiuse, globally distributed seismic network used by seismologists, to both characterize earthquakes and study the Earth’s interior. Most stations in the network have two collocated broadband seismometers, which enable network operators to identify potential metadata and sensor issues. In this study, we investigate the accuracy with which surface wavesAuthorsAdam T. Ringler, Robert E. Anthony, C. A. Dalton, David C.

We examine three continuously recording data sets related to the aurora: all‐sky camera images, three‐component magnetometer data, and vertical‐component, broadband seismic data as part of the EarthScope project (2014 to present). Across Alaska there are six all‐sky cameras, 13 magnetometers, and >200>200 seismometers. The all‐sky images and magnetometers have the same objective, which is to monitAuthorsC. Tape, Adam T.
