UWNSG Spouter Geyser

Here we share data collected at Spouter Geyser and Black Sand Basin, Yellowstone National Park, including near-surface geophysics (electrical resistivity tomography, transient electromagnetics, seismic refraction, nuclear magnetic resonance, ground-penetrating radar), time-lapse geophysical (electrical resistivity tomography, transient electromagnetics), and eruption duration (temperature transducer time-series). The subfolders and data files are detailed in the included \"Overview_of_Data.docx\" MS Word document.

These data construct a comprehensive, active geophysical investigation into the subsurface structure and geyser eruption dynamics at Spouter Geyser, Yellowstone National Park. The data were collected to constrain the subsurface geometry of Spouter Geyser and to characterize the subsurface structure. Additional time-lapse data highlights how the geophysical parameters change throughout the eruption cycle, informing conclusions about the eruption dynamics. A temperature transducer time-series allows the geophysical data to be correlated to the eruption cycle and provides insight into the geyser cycle duration over the past two decades.
