Summary

In July 2016, July 2019, and March 2020, 318 seismic recordings were acquired at locations within Shenandoah National Park, Virginia, using MOHO Tromino Model TEP-3C three-component seismometers to assess depth to bedrock using the HVSR method. This method requires a measurement of estimate of shear wave velocity, which depends on the regolith sediment composition and density, for the conversion of measured resonance frequency to a depth to bedrock. Shear wave velocities were calculated for sediment in Shenandoah NP at locations where regolith thickness is known (e.g. at documented boreholes). The locations in this study were generally selected to characterize the depths to bedrock adjacent to streams monitored for coupled temperature [...]

Purpose

Depth to bedrock can directly influence streamflow, shallow aquifer flow, and groundwater/surface water exchange but is typically ill-defined along the stream corridor in steep mountain catchments. We employed rapid, cost-effective passive seismic horizontal -to-vertical spectral ratio (HVSR) measurements to evaluate the variable thickness of the shallow colluvial and alluvial aquifer sediments along a headwater streams in Shenandoah National Park. The methods are fully documented in the research article, Briggs, M.A., J.W. Lane, C.D. Snyder, E.A. White, Z.C. Johnson, D.L. Nelms, and N.P. Hitt, 2018, Shallow mountain bedrock limits seepage-based headwater climate refugia, Limnologica, https://dx.doi.org/10.1016/j.limno.2017.02.005. This data release includes seismic data collected as part of a follow-on study.
