Joint geodetic and seismic analysis of surface crevassing near a seasonal glacier-dammed lake at Gornergletscher, Switzerland

Annals of Glaciology, 2019
Seasonal lake Gornersee forms at the confluence of Gornergletscher and Grenzgletscher, Switzerland, and experiences outburst floods annually in midsummer.

Detection of crevassed areas with minimum geometric information: Vernagtferner case study

Journal of Glaciology, 2023
Crevasses pose severe risks for mountaineers and field glaciologists. Smaller cracks between 0.5 and 2 m are still dangerous, but often not visible in medium resolution satellite imagery.

Crevasse initiation and history within the McMurdo Shear Zone, Antarctica

Journal of Glaciology, 2019
While large-scale observations of intensified fracture and rifting can be observed through remote-sensing observations, understanding crevasse initiation may best be achieved with small-scale observations in which crevasses can be directly observed. Here

The spatial distribution of potholes in Uusimaa, southern Finland [PDF]

Bulletin of the Geological Society of Finland, 1996
It has been assumed, on the basis of the distribution of potholes in the bedrock near eskers, that they were eroded by subglacial meltwaters connected with the formation of eskers.

Controls on Ice Cliff Distribution and Characteristics on Debris‐Covered Glaciers

Geophysical Research Letters, 2023
Ice cliff distribution plays a major role in determining the melt of debris‐covered glaciers but its controls are largely unknown. We assembled a data set of 37,537 ice cliffs and determined their characteristics across 86 debris‐covered glaciers within ...

Revised classification of glaciofluvial landforms in the Finnish sector of the Fennoscandian Ice Sheet

Boreas, EarlyView.
Effective and sustainable land use, conservation, and the use of geological resources (incl. raw materials, aggregates and groundwater) require a clear classification system of sedimentary units, with well‐defined vocabulary and unified mapping practices.

Crevasse effects on glacier surface temperature from thermal imagery

Journal of Glaciology
Thermal imagery was collected for 26 hours over a crevassed region within the accumulation zone of the Haupapa/Tasman Glacier, New Zealand. During the night, the imaged snow surfaces associated with crevasses cooled slower than non-crevassed surfaces ...

Electron microscopy‐based three‐dimensional subcellular imaging of plant male gametophyte

Journal of Integrative Plant Biology, EarlyView.
The Aquilos2 Cryo‐FIB workflows provide practical routes for cryo‐electron tomography and volume imaging in plant structural biology. ABSTRACT Understanding cellular events in three dimensions (3D) is of great importance for the annotation and illustration of biological processes in a contextual way. Imaging techniques based on electron microscopy (EM),

Structural provinces of the Ross Ice Shelf, Antarctica

Annals of Glaciology, 2017
The surface of the Ross Ice Shelf (RIS) is textured by flow stripes, crevasses and other features related to ice flow and deformation. Here, moderate resolution optical satellite images are used to map and classify regions of the RIS characterized by ...

The Influence of Sea Ice and Ice Mélange on Outlet Glacier Dynamics in the Arctic and Antarctic: Recent Progress and Future Challenges

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Sea ice is situated close to the termini of many outlet glaciers in the Arctic and Antarctic and has the potential to influence their dynamics and, therefore, their contribution to sea level rise. However, the nature, prevalence, and ice‐dynamic significance of sea ice‐glacier interactions remains subject to several open questions.
