The "tipping" temperature within Subglacial Lake Ellsworth, West Antarctica and its implications for lake access. [PDF]

, 2011
We present results from new geophysical data allowing modelling of the water flow within Subglacial Lake Ellsworth (SLE), West Antarctica. Our simulations indicate that this lake has a novel temperature distribution due to significantly thinner ice than ...

The Glacial Legacy of the Geneva Basin: Morphology and implications of an intricate tunnel valley system revealed from 3D seismic data

Journal of Quaternary Science, Volume 41, Issue 5, Page 732-753, July 2026.
ABSTRACT Like other perialpine basins and glaciated margins, the Geneva Basin in SW Switzerland is characterised by buried tunnel valleys, which are elongated incisions widely attributed to subglacial meltwater erosion beneath continental ice sheets. However, an inclusive understanding of the geological control on the evolution of the glacial landscape

Warm Surface Waters Dominate Melting of the Denman‐Shackleton Ice Shelf System

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract The ocean dynamics controlling the melting of the Denman‐Shackleton ice shelf system are investigated using a high‐resolution regional ocean‐sea ice‐ice shelf model. Our results show that basal meltwater production exhibits strong seasonal variability, driven by the ocean heat supply toward the ice shelf system, and occurs through two distinct

Quantifying subglacial roughness and its link to glacial geomorphology and ice speed [PDF]

, 2013
The shape of subglacial bed topography, termed its roughness, is a recognised control on basal ice-flow. Although glaciologists have observed patterns of variations in ice speed over beds with different roughness values, the strength of this relationship
