Journal of Glaciology, 2020 We developed a tilt sensor for studying ice deformation and installed our tilt sensor systems in two boreholes drilled close to the shear margin of Jarvis Glacier, Alaska to obtain kinematic measurements of streaming ice.

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.Abstract Landscapes formed by glacial erosion have previously been classified based on qualitative interpretation of geomorphic evidence, using aerial photography and field studies. In the current era of high‐resolution elevation data, limited attempts have been made to improve these classifications using quantitative measurements of landscape form (i ...

Instruments and methods: hot-water borehole drilling at a high-elevation debris-covered glacier
Journal of Glaciology, 2019 While hot-water drilling is a well-established technique used to access the subsurface of ice masses, drilling into high-elevation (≳ 4000 m a.s.l.) debris-covered glaciers faces specific challenges. First, restricted transport capacity limits individual

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.Abstract The bedrock beneath the Antarctic Ice Sheet has experienced widespread viscoelastic deformation as a response to ice‐sheet changes from the Last Glacial Maximum (LGM) to present day. The combined changes of the ice sheet and the bedrock most likely had impacted subglacial water routes.

Instruments and Methods Glacier Bore-Hole Photography
, 1973 A 51 mm diameter bore-hole camera allows observation of subglacial conditions, measurement of basal sliding rates, and study of internal structure and debris in ice at depth. The camera is simple in construction, field operation and maintenance.

Downscaling Daily Discharge to Sub‐Daily Scales for Alpine Glacierized Catchments
Water Resources Research, Volume 62, Issue 5, May 2026.Abstract Hydrological dynamics in glacierized catchments of the Alps are shaped by temperature‐driven processes, including snow and ice melt as well as precipitation, leading to diel streamflow cycles that vary in intensity within‐ and among‐the seasons.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract Ice cores from the Allan Hills blue ice area in Antarctica have been dated to several million years of age. However, the stratigraphy of these cores is often disturbed, and age reversals are common, hampering the interpretation of the derived climate records.

Ice‐Dynamic Constraints on Glacier Climatic Mass Balance Using Inverse Techniques
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Accurate glacier climatic mass balance (CMB) modeling relies on pertinent atmospheric data for forcing and in situ stake measurements for calibration, which are often sparse or unavailable in remote high‐mountain regions. This study presents a proof‐of‐concept for estimating glacier‐wide CMB fields by combining mass conservation and ice ...

Journal of Quaternary Science, Volume 41, Issue 3, Page 507-519, April 2026.ABSTRACT Complex relative sea‐level (RSL) changes are associated with the deglaciation of the British and Irish Ice Sheet (BIIS). Sediment archives from Loch Bad na h‐Achlaise, an isolation basin in NW Scotland, UK, span Late Glacial to Holocene time and record sea‐level change and ice proximity via a geochemical and biostratigraphic multiproxy ...
