Data for "Sparse Ambient Resonance Measurements Reveal Dynamic Properties of Freestanding Rock Arches". The Hive: University of Utah Research Data Repository. --------------------- DATA & FILE OVERVIEW --------------------- Each zipped folder, except MUSS, contains data for a single site (natural arch) included in the study, consisting of a 3D model and time-series seismic data. These zipped file types are described in File List A + B below. [TEXT] in brackets varies depending on the containing folder. Folder names are based on site names, given in Geimer_etal_2020_supportingmaterial.pdf 1. File List A. Filename: [ARCH_NAME].stl Short description: Photogrammetry-derived 3D triangular mesh model of the arch geometry, used for finite element analysis. B. Filename: [STATION_NAME]_[DATETIME].mseed (or *.miniseed) Short description: 1-hour ambient vibration time series data recorded at the site using 3-component Trillium Compact 20s broadband seismometers sampling at 100-250 Hz, saved in miniSEED format, with amplitudes representing raw counts. Station names ending in "A" are active stations placed directly on the arch span. Station names ending in "B" are reference stations. The file name also includes the starting datetime of the measurement in YYYYMMDD_HHMMSS format. C. Filename: trillium_compact_vel_pz.txt Short description: Pole-zero file describing the instrument response of Trillium Compact instruments, used to convert the data from counts to velocity with units of [m/s]. D. Filename: [STA].eh?.ms.sac (found only in MUSS folder) Short description: Ambient vibration time series data recorded in the dense array deployed at Musselman Arch using 3-component nodal geophones sampling at 250 Hz, saved in SAC format. {STA} is the individual station name. EH? is the individual component included in the file, with "?" changing to E, N, or Z for east, north, or vertical component data. 2. Relationship between files: Files within each zipped folder are all related to the site given by the folder name. The pole-zero file is applicable to all MSEED and miniSEED files. Nearly all seismic data (MSEED, SAC files) within a given folder was recorded simultaneously, exceptions noted in Geimer_etal_2020_supportingmaterial.pdf 3. Are there multiple versions of the dataset? no -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: Seismic data was collected with seismometers deployed using the methods described in Moore et al. (2016) "Anthropogenic sources stimulate resonance of a natural rock bridge". Seismometers and nodal geophones were placed directly onto bedrock to record ambient vibrations. Found at https://doi.org/10.1002/2016GL070088. 2. Methods for processing the data: The seismic data is submitted in its raw form, with amplitudes given in counts representing velocities. The 3D models were processed from photosets taken at each study site, with the sets directed into commercial photogrammetry software to produce the resulting 3D mesh geometry of each arch. 3. Instrument- or software-specific information needed to interpret the data: Seismic data was processed using the ObsPy package in Python. 3D models were generated using Bentley Context Capture photogrammetry software and Meshmixer editing software. Predicted study results from FEA methods were computed with COMSOL Multiphysics. 4. Environmental/experimental conditions: Environmental conditions of mean air and rock temperature recorded during each measurement are given in the Table 2 in Geimer_etal_2020_supportingmaterial.pdf. 5. People involved with sample collection, processing, analysis and/or submission: Geimer PR, Finnegan R, Moore JR, Hatch A, White B, Bodkter J, Vollinger K, and Richman N participated in deploying instruments at various sites, as well as taking the photos used in creation of the 3D models. Geimer PR, Finnegan R, and Moore JR processed and analyzed the data. Geimer PR, Finnegan R, and Hatch A constructed and refined the 3D models.
