Seismic Reflection and Electrical Resistivity Imaging Support Pre-Quaternary Glaciation in the Rocky Mountains (Unaweep Canyon, Colorado)
(2021-09-25)
Unaweep Canyon (Uncompahgre Plateau, Colorado) represents an enigmatic landscape with a complex evolution. Interpretations for its origin have ranged from ancestral fluvial erosion in the late Cenozoic to glacial erosion ...
Passive Processing of Active Nodal Seismic Data: Estimation of Vp∕Vs Ratios to Characterize Structure and Hydrology of an Alpine Valley Infill
(2019-08-15)
The advent of cable-free nodal arrays for conventional seismic reflection and refraction experiments is changing the acquisition style for active-source surveys. Instead of triggering short recording windows for each shot, ...
Seismic characterization of a rapidly-rising jökulhlaup cycle at the A.P. Olsen Ice Cap, NE-Greenland
(2020-02-04)
Rapidly-rising jökulhlaups, or glacial outburst floods, are a phenomenon with a high potential for damage. The initiation and propagation processes of a rapidly-rising jökulhlaup are still not fully understood. Seismic ...
