Deglaciation of the Burren glacio‐karst, western Ireland, during Termination 1: Implications for North Atlantic climate and karstification

Journal of Quaternary Science, Volume 41, Issue 5, Page 702-715, July 2026.
ABSTRACT The Burren uplands in western Ireland form one of the most extensive and best‐preserved examples of glacio‐karst in Europe. Subsumed by the Irish ice sheet during the Late Pleistocene, granite erratic boulders and in situ silica veins in the limestone bedrock provide a rare opportunity to reconstruct the timing and rate of deglaciation ...

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

ENVIRONMENT PROTECTION AND ENVIRONMENT MONITORING ISSUES IN THE PROJECTS OF SUBGLACIAL LAKES STUDIES IN ANTARCTICA

Лëд и снег, 2015
Antarctic subglacial lakes can represent extreme natural habitats for microorganisms from the position of their evolution and adaptation, as well as they can contain the information on Antarctic ice sheet history and climatic changes in their sediments ...

The Impact of Subglacial Drainage System Evolution and Glacier Lake Outburst on Arctic Fjord Macronutrient Dynamics

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Global warming is amplified in the Arctic, accelerating glacier melt and freshwater runoff. At tidewater glaciers, runoff typically enters fjords at depth and generates buoyancy‐driven circulation that enhances glacier‐ocean exchanges of energy and matter, influencing macronutrient delivery and marine primary production.

A glaciotectonic landform in the Shyok valley, Trans-Himalayan Karakoram Range, India

Journal of Glaciology
This study reports and discusses the first case of glaciotectonic landforms in the Shyok valley of the Trans-Himalayan Karakoram Range, Ladakh, where a large decomposed granite megablock (8.2 km2) along with underlying diamicton is thrust over the ...

Glacier sliding, seismicity and sediment entrainment

Annals of Glaciology, 2019
The evolution of glaciers and ice sheets depends on processes in the subglacial environment. Shear seismicity along the ice–bed interface provides a window into these processes. Such seismicity requires a rapid loss of strength that is typically ascribed

Sedimentological and mineralogical characteristics of active glacial sediments in the Indian Himalaya regions

Geology, Ecology, and Landscapes, 2020
Glaciated sediments are a significant source to know the glacier environment processes. Glacial meltwater streams draining from the Himalayan glaciers carry with a different type of sediment sizes, because of the supraglacial, englacial, and subglacial ...

Grain-size distribution and origins of unconsolidated fine sediments in ice-free areas, Soya Coast, East Dronning Maud Land, East Antarctica

Antarctic Record, 2005
Unconsolidated fine sediments (UFS), sporadically deposited in Soya Coast ice-free areas, have often been described as glacial deposits (till) or subglacial till in previous studies, but their genesis and depositional environments have never been ...

Basal conditions at Engabreen, Norway, inferred from surface measurements and inverse modelling

Journal of Glaciology, 2018
Engabreen is an outlet glacier of the Svartisen Ice Cap located in Northern Norway. It is a unique glacier due to the Svartisen Subglacial Laboratory which allows direct access to the glacier bed.
