Assessing the catastrophic break-up of Briksdalsbreen, Norway, associated with rapid climate change

, 2011
Recent research has raised concerns about the potential influence of rapid climate change on the stability of major ice sheets. The behaviour of glaciers is determined largely by the processes and conditions operating at their base.

Image analysis techniques to estimate river discharge using time-lapse cameras in remote locations [PDF]

, 2015
Cameras have the potential to provide new data streams for environmental science. Improvements in image quality, power consumption and image processing algorithms mean that it is now possible to test camera-based sensing in real-world scenarios.

Global Glacial Rock Weathering Signature Depends on Competing Contributions From Ice Sheets and Alpine Glaciers

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Rock weathering influences Earth's atmosphere and climate. The dissolution of silicate minerals draws down atmospheric CO2 while sulfide oxidation coupled with carbonate dissolution releases CO2. Alpine glacier rock weathering causes high sulfide oxidation and carbonate dissolution.

Climate Warming and Ice Weakening Trigger Alpine Glacier Collapses: The Marmolada Case

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The rapid retreat of temperate mid‐latitude glaciers due to global warming causes dramatic mass loss and increases their instability. Using a synthesis of thermodynamic and mechanical laws, we constructed a three‐dimensional stability model and applied it in the analysis of the collapse of a portion of the Marmolada Glacier in northeastern ...

Glacial Ice‐Front Calving: Internal Wave Generation and Melting

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Small, frequent calving events dominate the behavior of most Arctic marine‐terminating glaciers, yet their oceanographic impacts remain largely unquantified. We present the first direct observations of internal waves generated by modest ice‐fall calving at Kronebreen, Svalbard. High‐resolution current meter and microstructure measurements show

Streamlined subglacial bedforms across isolated topographic highs in the Puget Lowland, Washington state

, 2023
These data include shapefiles of streamlined subglacial bedforms, elongate bedforms created at the glacier-bed interface by erosional and depositional processes, characterized by polygons across nine isolated bedrock highs in the deglaciated Puget ...

Seasonal Ice Dynamics Control the Timing of Crevasse Drainage at a Fast‐Flowing Outlet Glacier

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Crevasse field drainage transfers at least half of the seasonal runoff from the surface to the bed of the Greenland Ice Sheet, but the patterns of drainage are complex and spatio‐temporally heterogenous. To better understand controls on crevasse drainage processes, we use an automated deep learning method to map the seasonal filling and ...

The Causes and Implications of Microstructures in Glacial Sediments [PDF]

, 1998
This thesis examines how microstructures in glaciogenic sediments reflect the processes forming them, and how these microstructures then affect the conditions around them, through a series of field studies, laboratory tests, models, and statistical ...

Analysis of long-term dynamic changes of subglacial lakes in the Recovery Ice Stream, Antarctica [PDF]

The Cryosphere
The dynamic activity of subglacial lakes plays a crucial role in modulating glacial processes and the mass balance of the Antarctic ice sheet. The Recovery Ice Stream (RIS), projected to experience significant mass loss in East Antarctica during coming ...
