We conducted laboratory studies on the geophysical signals from Arctic saline permafrost
soils to help understand the physical and mechanical processes during freeze-thaw cycles …

Surface waves are advantageous for mapping seismic structures of permafrost, in which
irregular velocity gradients are common and thus the effectiveness of refraction methods are …

Seismic attenuation α, or internal friction Q− 1, in glacial ice is highly sensitive to
temperature, particularly near the melting point. Here we detail a technique to estimate Q …

Existing data on the acoustic properties of low-temperature biological materials is limited
and widely dispersed across fields. This makes it difficult to employ this information in the …

The ability to quantitatively and non-invasively characterize complex multiphase
geomaterials is still a major challenge to the engineering, construction, and geophysical …

The presence of partially frozen liquid in the pore spaces of porous materials has significant
effects on elastic wave propagation. Although the characterization of partially frozen systems …

The elastic and anelastic properties of ice are of interest in the study of the dynamics of sea
ice, glaciers, and ice sheets. Resonant ultrasound spectroscopy allows quantitative …

Current geophysical exploration methods face challenges in accurately determining gas
saturation levels and elastic constants with adequate spatial resolution. Seismic wave …

Determining the development of artificial frozen walls by present methods is challenging
where substantial seepage occurs because fixed monitoring points only indicate physical …

Monitoring the change in permafrost conditions and distribution is crucial for forecasting
global warming. As seismic velocities increase with ice content, marine seismic surveys can …
