Uplift of the Transantarctic Mountains: Evidence for an Evolving and Long‐Lived Rayleigh‐Taylor Instability

Tectonics, Volume 45, Issue 8, August 2026.
Abstract Rayleigh‐Taylor instabilities within the upper mantle are investigated as a mechanism for the uplift of rift‐margin mountain ranges within the continents. Our focus is on the Transantarctic Mountains (TAM). These mountains form at the margin between East and West Antarctica and have been free from the effects of subduction for about 500 ...

Totten Glacier subglacial hydrology determined from geophysics and modeling

Earth and Planetary Science Letters, 2020
Aurora Subglacial Basin (ASB), which feeds Totten Glacier, is a marine basin lying below sea level and contains up to 3.5m of global sea level equivalent. Rates of future sea level rise from this area are primarily dependent on the stability of Totten Ice Shelf and the controls on ice flow dynamics upstream of the grounding line, both of which may be ...

Geophysical Characterization of the Furggwanghorn Rock Glacier, Switzerland

Proceedings, 2012
Degradation of alpine permafrost due to changing mean annual air temperatures can act as trigger for landslides and other ground instabilities. For a better understanding of the underlying thermo-hydromechanical processes an interdisciplinary research project has been set up.

Integrated geophysical measurement on the Hallstatter glacier (Austria)

54th EAEG Meeting, 1992
Study of glaciers may contribute to the solution of some scientific problems which have become important recently. More accurate determination of the size and geometry of glaciers may result in a more accurate estimation of the potential fresh water reserves and of impacts of climatic changes.

Measurement of glacier geophysical properties from insar wrapped phase

IEEE Transactions on Geoscience and Remote Sensing, 2003
A method is presented for calculating longitudinal glacier strain rates directly from the wrapped phase of an interferometric synthetic aperture radar (InSAR) interferogram assuming the ice flow path is known. This technique enables strain rates to be calculated for scenes lacking any velocity control points or areas within a scene where the phase is ...

Multidisciplinary geophysical investigations over an alpine rock glacier

Geophysics, 2015
ABSTRACT We have performed a multidisciplinary geophysical survey combined with geotechnical investigations over a degrading alpine rock glacier. A dense grid of helicopter-borne ground-penetrating radar data allowed the 3D shape of the bedrock topography and the gross transition from ice-rich to ice-poor parts of the rock glacier to ...

Glaciers and geophysics

Eos, Transactions American Geophysical Union, 1933
To consider the relation of glaciation to other branches of geophysics we must first develop the cause of glaciation; and this will require us to recall some ideas which, though elementary, are fundamental, and it is by keeping fundamental principles in mind that we can build most securely the superstructure.The first requisite for glaciation is the ...
