A revised inventory of Antarctic subglacial lakes [PDF]

, 2005
The locations and details of 145 Antarctic subglacial lakes are presented. The inventory is based on a former catalogue of lake-type features, which has been subsequently reanalysed, and on the results from three additional datasets.

Sediment Characteristics and Architecture of Triangular‐Shaped Murtoos: A Test of Murtoo Formation Hypotheses

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Murtoos and murtooized terrains are new types of subglacial landforms found in the Fennoscandian Ice Sheet (FIS) and Cordilleran Ice Sheet (CIS) regions. LiDAR‐based morphometric analyses have revealed substantial morphometric diversity among murtoos and murtoo‐related landforms, while sedimentological excavations have documented a wide range of ...

Microbiology: lessons from a first attempt at Lake Ellsworth [PDF]

, 2015
During the attempt to directly access, measure and sample Subglacial Lake Ellsworth in 2012–2013, we conducted microbiological analyses of the drilling equipment, scientific instrumentation, field camp and natural surroundings.

Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...

Hydrological controls on diurnal ice flow variability in valley glaciers [PDF]

, 2005
This paper uses a combination of field data and three-dimensional modeling to investigate the spatial variability in basal conditions required to induce observed fluctuations in diurnal ice velocity at Haut Glacier d'Arolla, Switzerland.

Drivers of Dissolved Thorium Isotope Distributions Along the Adélie Land Margin, East Antarctica: The Roles of Reversible Scavenging, Conservative Transport, and Lithogenic Supply

Global Biogeochemical Cycles, Volume 40, Issue 9, September 2026.
Abstract In this study, we present a mix of full‐depth profiles and near‐bottom observations of dissolved 230Th and 232Th from the Adélie Land margin in East Antarctica, a key site of Antarctic Bottom Water (AABW) formation. We show that the distribution of dissolved Th isotopes in this region is governed by a combination of reversible scavenging ...

Hydraulic impacts of glacier advance over a sediment bed [PDF]

, 2006
A sedimentary sequence of till overlying a gravel aquifer was instrumented with water-pressure transducers prior to a small, anticipated surge of the margin of the glacier Breiðamerkurjökull in Iceland.

Climate Models Accurately Predict Ocean‐Going Meltwater Runoff From the Northwest Greenland Ice Sheet

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Climatic surface mass balance (SMB) meltwater runoff models are used to estimate current and future Greenland Ice Sheet sea level contributions. However, comparisons between SMB model runoff and in situ proglacial river discharge observations show large discrepancies.

Incorporation of particulates into accreted ice above subglacial Vostok lake, Antarctica [PDF]

, 2005
The nature of microscopic particulates in meteoric and accreted ice from the Vostok (Antarctica) ice core is assessed in conjunction with existing ice-core data to investigate the mechanism by which particulates are incorporated into refrozen lake water.

Crack wave resonances within the basal water layer

Annals of Glaciology, 2019
Hydraulic processes within and beneath glacial bodies exert a far-reaching control on ice flow through their influence on basal sliding. Within the subglacial system, rapid changes in these processes may excite resonances whose interpretation requires an
