Subglacial drainage processes at a High Arctic polythermal valley glacier [PDF]
, 2005 Dye-tracer experiments undertaken over two summer melt seasons at polythermal John Evans Glacier, Ellesmere Island, Canada, were designed to investigate the character of the subglacial drainage system and its evolution over a melt season. In both summers,

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract The Siple Coast region of West Antarctica is known for its fast flowing, topographically unconstrained ice streams that evolve due to subglacial conditions. In this work, we analyze the nature of the Siple Coast subglacial hydrologic system and its interactions with the ice sheet using two‐way coupled subglacial hydrology and ice flow modeling.

A Glacial Fjord Box Model: Derivation and Representation of Glacially Modified Water
Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.Abstract Fjords are a crucial connection between the Greenland Ice Sheet and the ocean, but remain unrepresented at the scale of many Earth System Models. To parameterize mixing within them, we modify a two‐layer estuary box model to include buoyant plumes, which are common features of glacial fjords.

Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract Accurately estimating Snow Water Equivalent (SWE) in glacierized regions is critical for glacier modeling and mass balance analysis yet remains challenging due to sparse observations and uncertainties in precipitation products. The objectives are twofold: (a) assess how well three widely used precipitation datasets—Stage IV (a radar–gauge ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract Accurate characterization of the compressional to shear (P‐to‐S) wave‐speed ratio (vp/vs ${v}_{p}/{v}_{s}$) within the Antarctic Ice Sheet (AIS) is crucial for understanding its internal structure, mechanical stability, and vulnerability to a changing climate.

AGU Advances, Volume 7, Issue 5, August 2026.Abstract The evolution and connectivity of subglacial drainage systems control basal sliding and therefore modulate ice motion, yet direct observations of these systems remain limited. Here, we investigate hydraulic connectivity and its influence on ice motion at Isunnguata Sermia, a large land‐terminating outlet glacier of the Greenland Ice Sheet.
