Gravity modelling of ice thickness and valley geometry on Taku Glacier (T'aak̲ú K̲wáan Sít'i), Alaska

Journal of Glaciology
Taku Glacier recently began retreating for the first time since the late 19th century but limited observations of its bed leaves uncertainties on how this retreat will proceed. In this study, we use ground-based gravity measurements to improve the extent

Ice thickness measurements of Guliya ice cap, western Kunlun Mountains (Tibetan Plateau), China

Journal of Glaciology, 2018
Despite their high value and importance for various glaciological applications, detailed ice thickness measurements of alpine glaciers are still very limited. Knowledge of bedrock topography is essential for paleoglaciological studies. The Guliya ice cap

Ice mass discharge through the Antarctic subglacial hydrographic network as a trigger for cryoseismicity

Journal of Glaciology
We analyse seismic time series collected during experimental campaigns in the area of the David Glacier, Victoria Land, Antarctica, between 2003 and 2016.

Glacier bed surveying with helicopter-borne dual-polarization ground-penetrating radar

Journal of Glaciology, 2019
Traditionally, helicopter-borne ground-penetrating radar (GPR) systems are operated with a single pair of bistatic dipole antennas to measure the thickness of glaciers.

Glacier thickness modelling and monitoring with geophysical data constraints: A case study on the Indren Glacier (NW Italy)

Earth Surface Processes and Landforms
AbstractThe ongoing global temperature increase has accelerated the mass loss of glaciers worldwide, with Italian alpine glaciers being particularly vulnerable due to their small size, complex geometries and exposition that implies a fast reaction to thermal and hydrological modifications.

Thickness of Ruth Glacier, Alaska, and depth of its Great Gorge from ice-penetrating radar and mass conservation

Journal of Glaciology
Ruth Glacier is situated in the Central Alaska Range, with the Don Sheldon Amphitheater comprising much of its broad accumulation area, directly adjacent to North America's tallest mountain, Denali.

Sustained rapid shrinkage of Yukon glaciers since the 1957–1958 International Geophysical Year

Geophysical Research Letters, 2010
Glaciers in the Yukon, NW Canada, lost 22% of their surface area during the 50 years following the 1957–58 International Geophysical Year, coincident with increases in average winter and summer air temperatures and decreases in winter precipitation. Scaling these results to ice volume change, we obtain a total mass loss of 406 ± 177 Gt, which accounts ...

Glacio-limnological interactions at lake-calving glaciers

, 2012
Iceberg calving is an efficient ablation process which introduces mechanical instability to glacier systems and can cause non-linear climatic response.

Penetration of Antarctic subglacial lakes by VHF electromagnetic pulses: Information on the depth and electrical conductivity of basal water bodies

, 1999
Owing to the high level of absorption of very high frequency radio waves in water, previous investigators of airborne radio echo sounding (RES) data from Antarctica have assumed that the depth of subglacial lakes cannot be measured directly by this ...
