Journal of GlaciologySurface meltwater can influence subglacial hydrology and ice dynamics if it reaches ice sheet's base. Firn aquifers store meltwater and drain into wide crevasses marking the aquifer's downstream boundary, indicating water from firn aquifers can drive ...

Rates of Sea‐Level Rise Are Highly Sensitive to Ice Viscosity Parameters in Model Benchmarks
AGU Advances, Volume 7, Issue 2, April 2026.Abstract Glacier flow plays a major role in current and future rates of globally averaged sea‐level rise. The viscosity of glacial ice, controlling the rate of flow, decreases as stress increases and is highly sensitive to the value of the stress exponent, n $n$, in the constitutive equation for viscous flow.

Autonomous FMCW Radar Survey of Antarctic Shear Zone [PDF]
, 2010 Radar survey of the Antarctic shear zone was conducted using an ultra-wideband (2-10 GHz) frequency modulated continuous wave (FMCW) radar. The radar was mounted on a sled and pulled by a robot that was specifically designed to operate in a harsh polar ...

AGU Advances, Volume 7, Issue 2, April 2026.Abstract Surface meltwater impacts Greenland Ice Sheet mass balance indirectly by reducing albedo and promoting hydrofracture. However, fully understanding both processes requires accurate mapping of small‐scale features such as ponds, channels, and moulins that govern meltwater formation and drainage. Here we investigate surface water dynamics at high

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.The study focusses on the morphological evolution of worldwide restored intertidal flats. These intertidal flats initially experience high sedimentation rates after the opening of the connection with open waters. The anthropogenic structures cause high morphological instability and are eroded, leading to a self‐cannibalisation of the system.

Grounding-line basal melt rates determined using radar-derived internal stratigraphy [PDF]
, 2010 We use ice-penetrating radar data across grounding lines of Siple Dome and Roosevelt Island, Antarctica, to measure the spatial pattern, magnitude and duration of sub-ice-shelf melting at these locations.

Three‐Dimensional Simulation of Crack Initiation in ice Shelves at Pinning Points
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.ABSTRACT Ice shelves are large ice masses floating on the ocean that are still connected to the inland ice of a glacier. Due to high elevations in the bathymetry, the ice shelf can be partially grounded. These areas are called ice rises that act as pinning points.

Southern Ocean warming: Increase in basal melting and grounded ice loss [PDF]
, 2013 We apply a global finite element sea ice/ice shelf/ocean model (FESOM) to the Antarctic marginal seas to analyze projections of ice shelf basal melting in a warmer climate.

Impacts of Temperature‐ and Stress‐Dependent Rheology on Ice‐Shelf‐Front Bending
Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.Abstract Classical treatments of ice‐shelf bending suggest that shelf fronts should bend downwards, due to the distribution of hydrostatic water pressure at the front. However, LiDAR data show several instances of upward‐bending ice‐shelf fronts. While this phenomenon has often been attributed to a buoyant force from a submerged ice bench, recent work ...
