Regolith, rock and <em>fluid</em> distributions at the Upper Colorado River Basin via a multicomponent seismic imaging approach

Surface geophysical measurements can link geologic, geomorphic and hydrologic processes. Characterizing subsurface properties at sufficient resolution, yet over a large enough spatial extent to make statistically relevant correlations between subsurface structure and surface observations (topographic attributes, vegetation, etc.), is currently not standard practice because ground-based geophysical campaigns are limited by acquisition rates. The seismic land streamer is a semiautonomous vehicle-mounted acquisition system designed to pull geophone arrays and a seismic source to rapidly acquire large data volumes compared to traditional planted geophone surveys. Acquisition geometry is well suited for obtaining first arrivals to constrain p-wave velocities (Vp), Rayleigh waves to constrain shear-wave (Vs) velocities and reflections to map significant subsurface stratigraphy. Joint and/or independent analysis of these semi-independent data sources reduce uncertainties in data interpretation.
