Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.Abstract The East Antarctic Ice Sheet (EAIS) formed circa 34 million years ago and now contains an ice volume equivalent to ∼52 m of global sea‐level rise. Although the EAIS is approximately in balance today, there is substantial uncertainty regarding the sensitivity of sectors underlain by low‐lying bed topography to future climate and ocean warming ...

Primary Transverse Crevasses [PDF]
Journal of Glaciology, 1969 Measurements of strain-rates on a temperate glacier in a region of initial transverse fracturing indicate a critical strain-rate of 3.5±0.5 × 10−5 d−1, associated with a regional strain-rate gradient of 5 × 10−8 d−1 m−1. At only one section of the glacier is the theoretical longitudinal strain-rate (Nye, 1959[c]) in approximate agreement with the value

Parquet: Regions of areal plastic dislocations (on Venus) [PDF]
The extensive flat elevations of the Northern Hemisphere of Venus are covered with frequently intersecting lines of dislocations, resembling the outline of a giant parquet.

Modelling environmental influences on calving at Helheim Glacier in eastern Greenland [PDF]
, 2014 Calving is an important mass-loss process for many glaciers worldwide, and has been assumed to respond to a variety of environmental influences. We present a grounded, flowline tidewater glacier model using a physically-based calving mechanism, applied ...

Horizontal force-balance calving laws: Ice shelves, marine- and land-terminating glaciers
Journal of GlaciologyPredicting calving in glacier models is challenging, as observations of diverse calving styles appear to contradict a universal calving law. Here, we generalize and apply the analytical Horizontal Force-Balance fracture model from ice shelves to land ...

Classification of calving fronts around Antarctica [PDF]
, 2012 Iceberg calving is the largest loss term in Antarctic mass balance. The iceberg areas vary from a few square meters (growler) to several hundred square kilometres (huge tabular icebergs or ice islands) and their shape (blocky, domed or tabular) depends ...

Assessing future ice shelf hydrofracture vulnerability in the ISMIP6 ensemble
Journal of GlaciologyUnderstanding the possibility of future ice shelf collapses similar to that of the Larsen B is critical for improving sea-level-rise projections due to the restraint on upstream flow that ice shelves provide.

Melt regimes, internal stratigraphy, and flow dynamics of three glaciers in the Alaska Range [PDF]
, 2012 We used ground-penetrating radar (GPR), GPS and glaciochemistry to evaluate melt regimes and ice depths, important variables for mass-balance and ice-volume studies, of Upper Yentna Glacier, Upper Kahiltna Glacier and the Mount Hunter ice divide, Alaska.

Quantifying supraglacial meltwater pathways in the Paakitsoq region, West Greenland
Journal of Glaciology, 2017 Increased summer ice velocities on the Greenland ice sheet are driven by meltwater input to the subglacial environment. However, spatial patterns of surface input and partitioning of meltwater between different pathways to the base remain poorly ...
