Magnetic field variations in Alaska: Recording space weather events on seismic stations in Alaska
Seismometers are highly sensitive instruments to not only ground motion but also many other nonseismic noise sources (e.g., temperature, pressure, and magnetic field variations). We show that the Alaska component of the Transportable Array is particularly susceptible to recording magnetic storms and other space weather events because the sensors used in this network are unshielded and magnetic fluAuthorsAdam T. Ringler, Robert E. Anthony, David C. Wilson, Abram E. Claycomb, John SpritzerInstallation and performance of the Albuquerque Seismological Laboratory small-aperture posthole array
The Global Seismographic Network (GSN) has been used extensively by seismologists to characterize large earthquakes and image deep earth structure. While some of the networks design goals have been met, the seismological community has suggested that the incorporation of small-aperture seismic arrays at select sites may improve performance of the network and enable new observations. As a pilot stuAuthorsRobert E. Anthony, Adam T. Ringler, David C. Wilson, J. Zebulon Maharrey, Gary Gyure, Aaron Pepiot, Leo D. Sandoval, Samuel Sandoval, Thomas Telesha, Gilbert Vallo, Nicholas VossHow processing methodologies can distort and bias power spectral density estimates of seismic background noise
Power spectral density (PSD) estimates are widely used in seismological studies to characterize background noise conditions, assess instrument performance, and study quasi‐stationary signals that are difficult to observe in the time domain. However, these studies often utilize different processing techniques, each of which can inherently bias the resulting PSD estimates. The level of smoothing, thAuthorsRobert E. Anthony, Adam T. Ringler, David C. Wilson, Manochehr Bahavar, Keith D. KoperA brief introduction to seismic instrumentation: Where does my data come from?
Modern seismology has been able to take advantage of several technological advances. These include feedback loops in the seismometer, specialized digitizers with absolute timing, and compression formats for storing data. While all of these advances have helped to improve the field, they can also leave newcomers a bit confused. Our goal here is to give a brief overview of how recordings of seismAuthorsAdam T. Ringler, Patrick BastienUsing component ratios to detect metadata and instrument problems of seismic stations: Examples from 18 years of GEOSCOPE data
Replacement or deterioration of seismic instruments and the evolution of the installation conditions and sites can alter the seismic signal in very subtle ways, so it is notoriously difficult to monitor the signal quality of permanent seismic stations. We present a simple tool, energy ratios between each pair of the three recorded components, aimed at characterizing and monitoring signal quality,AuthorsHelle A. Pedersen, Nicolas Leroy, Dimitri Zigone, Martin Vallée, Adam T. Ringler, David C. WilsonCalibration analysis and noise estimates of WWSSN Station ALQ (Albuquerque, New Mexico)
World‐Wide Standardized Seismograph Network (WWSSN) records contain daily calibration pulses that can be used to retrieve the magnification as well as the response of the instrument for a given day record. We analyze a select number of long‐period vertical (LPZ) records from WWSSN station ALQ (Albuquerque, New Mexico). Although we find that the response of this instrument varies widely throughoutAuthorsAdam T. Ringler, David C. Wilson, Emily Wolin, Tyler Storm, L. D. SandovalImprovements in seismic resolution and current limitations in the Global Seismographic Network
Station noise levels play a fundamental limitation in our ability to detect seismic signals. These noise levels are frequency-dependent and arise from a number of physically different drivers. At periods greater than 100 s, station noise levels are often limited by the self-noise of the instrument as well as the sensitivity of the instrument to non-seismic noise sources. Recently, station operaAuthorsAdam T. Ringler, J. Steim, David C. Wilson, R. Widmer-Schnidrig, Robert E. AnthonyRapid station and network quality analysis for temporary deployments
Seismic station data quality is commonly defined by metrics such as data completeness or background seismic noise levels in specific frequency bands. However, for temporary networks such as aftershock deployments or induced seismicity monitoring, the most critical metric is often how well the station performs when recording events of interest. A timely measure of station performance can be usedAuthorsDavid C. Wilson, Adam T. Ringler, Tyler Storm, Robert E. AnthonyCharacteristics and spatial variability of wind noise on near-surface broadband seismometers
By coupling with the ground, wind causes ground motion that appears on seismic records as noise across a wide bandwidth. This wind-generated noise can drown out important features such as small earthquakes and prevent observation of normal modes from large earthquakes. Because the wind field is heterogeneous at local scales due to structures, diurnal heating, and topography, wind-induced seismic nAuthorsS. N. Dybing, Adam T. Ringler, David C. Wilson, Robert E. AnthonyRayleigh wave ellipticity measurement uncertainty across the IRIS/USGS and New China Digital Seismograph Networks
Long-period Rayleigh wave horizontal to vertical amplitude (H/V) ratios at a station provide information about local earth structure that is complementary to phase velocity. However, a number of studies have observed that significant scatter appears in these measurements making it difficult to use H/V ratio measurements to resolve earth structure. Some of the scatter in these measurements has beenAuthorsAdam T. Ringler, David C. Wilson, Walter Zürn, Robert E. AnthonyA collection of historic seismic instrumentation photographs at the Albuquerque Seismological Laboratory
The Albuquerque Seismological Laboratory (ASL) has preserved a collection of photographs of seismographic equipment, stations, and drawings used by the United States Coast and Geodetic Survey (USC&GS) in the early-to-mid-twentieth century.

From 1961 to 1996, the Albuquerque Seismological Laboratory (ASL) installed and operated the World‐Wide Standardized Seismograph Network (WWSSN). Each station within the network consisted of three Benioff short‐period sensors and three Sprengnether Press‐Ewing long‐period sensors along with recording, timing, and calibration equipment.
