Area and borders of Antarctic and permafrost—A review and synthesis

W Dobiński, JE Szafraniec… - Permafrost and Periglacial …, 2023 - Wiley Online Library
The Antarctic continent is a crucial area for ultimate determination of permafrost extent on
Earth, and its solution depends on the theoretical assumptions adopted. In fact, it ranges …

Satellite record reveals 1960s acceleration of Totten Ice Shelf in East Antarctica

R Li, Y Cheng, T Chang, DE Gwyther, M Forbes… - Nature …, 2023 - nature.com
Abstract Wilkes Land and Totten Glacier (TG) in East Antarctica (EA) have been losing ice
mass significantly since 1989. There is a lack of knowledge of long-term mass balance in the …

Troughs developed in ice-stream shear margins precondition ice shelves for ocean-driven breakup

KE Alley, TA Scambos, RB Alley, N Holschuh - Science advances, 2019 - science.org
Floating ice shelves of fast-flowing ice streams are prone to rift initiation and calving
originating along zones of rapid shearing at their margins. Predicting future ice-shelf …

Softening of temperate ice by interstitial water

CJC Adams, NR Iverson, C Helanow, LK Zoet… - Frontiers in Earth …, 2021 - frontiersin.org
Ice at depth in ice-stream shear margins is thought to commonly be temperate, with
interstitial meltwater that softens ice. Models that include this softening extrapolate results of …

Thermal controls on ice stream shear margins

P Hunter, C Meyer, B Minchew, M Haseloff… - Journal of …, 2021 - cambridge.org
Ice stream discharge responds to a balance between gravity, basal friction and lateral drag.
Appreciable viscous heating occurs in shear margins between ice streams and adjacent …

Glacier sliding, seismicity and sediment entrainment

BP Lipovsky, CR Meyer, LK Zoet, C McCarthy… - Annals of …, 2019 - cambridge.org
The evolution of glaciers and ice sheets depends on processes in the subglacial
environment. Shear seismicity along the ice–bed interface provides a window into these …

Characterizing the ice-ocean interface of icy worlds: A theoretical approach

JJ Buffo, BE Schmidt, C Huber, CR Meyer - Icarus, 2021 - Elsevier
We investigate the structure and evolution of multiphase ice-ocean interfaces ('mushy
layers') and the implications for the geophysics and habitability of ice-ocean worlds …

Inferring ice fabric from birefringence loss in airborne radargrams: Application to the eastern shear margin of Thwaites Glacier, West Antarctica

TJ Young, DM Schroeder, TM Jordan… - Journal of …, 2021 - Wiley Online Library
In airborne radargrams, undulating periodic patterns in amplitude that overprint traditional
radiostratigraphic layering are occasionally observed, however, they have yet to be …

A new approach to inferring basal drag and ice rheology in ice streams, with applications to West Antarctic Ice Streams

M Ranganathan, B Minchew, CR Meyer… - Journal of …, 2021 - cambridge.org
Drag at the bed and along the lateral margins are the primary forces resisting flow in outlet
glaciers. Simultaneously inferring these parameters is challenging since basal drag and ice …
