Rock glacier composition and structure from radio wave speed analysis with dipping reflector correction

Autor: Tyler M. Meng, Eric I. Petersen, John W. Holt

Publikováno v: Journal of Glaciology, Vol 69, Pp 639-657 (2023)

We assess the composition and geometry of four individual rock glaciers in Alaska, Wyoming and Colorado by measuring their radio wave speed and applying these results to ground-penetrating radar depth corrections and dielectric mixing models. Our met

Photogrammetric Monitoring of Rock Glacier Motion Using High-Resolution Cross-Platform Datasets: Formation Age Estimation and Modern Thinning Rates

Autor: Tyler M. Meng, Roberto Aguilar, Michael S. Christoffersen, Eric I. Petersen, Christopher F. Larsen, Joseph S. Levy, John W. Holt

Publikováno v: Remote Sensing, Vol 15, Iss 19, p 4779 (2023)

The availability of remote sensing imagery at high spatiotemporal resolutions presents the opportunity to monitor the surface motion of rock glaciers, a key constraint for characterizing the dynamics of their evolution. In this paper, we investigate

Geometry and ice dynamics of the Darwin–Hatherton glacial system, Transantarctic Mountains

Autor: METTE K. GILLESPIE, WENDY LAWSON, WOLFGANG RACK, BRIAN ANDERSON, DONALD D. BLANKENSHIP, DUNCAN A. YOUNG, JOHN W. HOLT

Publikováno v: Journal of Glaciology, Vol 63, Pp 959-972 (2017)

The Darwin–Hatherton Glacial system (DHGS) connects the East Antarctic Ice Sheet (EAIS) with the Ross Ice Shelf and is a key area for understanding past variations in ice thickness of surrounding ice masses. Here we present the first detailed measu

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

Autor: Brandon S. Tober, Michael S. Christoffersen, John W. Holt, Martin Truffer, Christopher F. Larsen

Publikováno v: Journal of Glaciology, Pp 1-10

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. From there it funnels through the ‘Great Gorge,�
