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 ...

Frontiers in Earth Science, 2020 Projections of future ice sheet mass loss and thus sea level rise rely on the parametrization of iceberg calving in ice sheet models. The interconnection between submarine melt-induced undercutting and calving is still poorly understood, which makes ...

Are seasonal calving dynamics forced by buttressing from ice mélange or undercutting by melting? Outcomes from full-Stokes simulations of Store Gletscher, West Greenland [PDF]
, 2014 . We use a full-Stokes 2-D model (Elmer/Ice) to investigate the flow and calving dynamics of Store Gletscher, a fast flowing outlet glacier in West Greenland.

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.Abstract The unexpected collapse of the Marmolada Glacier in the Italian Alps on 3 July 2022, caused 11 fatalities and emphasized the need for a deeper understanding of unstable glaciers. In response, we initiated a radar monitoring campaign to assess the stability of the remaining ice cliff and obtained a near‐continuous data set of displacement at ...

Effects of geometry on the seismic wavefield of Alpine glaciers
Annals of Glaciology, 2019 Passive seismology allows measurement of the structure of glaciers and ice sheets. However, most techniques used so far in this context are based on horizontally homogeneous media where parameters vary only with depth (1-D approximations), which are ...

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Snow dampens sounds, but anecdotal reports concisely describe audible propagating collapse events—firnquakes—in Antarctic and Arctic snowfields. We propose combining granular and continuum mechanics to form a testable theory for conditioning, triggering, and propagation of firnquakes consistent with scarce data.

Annals of Glaciology, 2019 Changing rates of water input can affect both the flow of glaciers and ice sheets and their propensity to crevasse. Here we examine geodetic and seismic observations during two substantial (10–18-times background velocity) rain-induced glacier ...

Formation of De Geer Moraines Deposited Subglacially, Central Québec [PDF]
, 1995 This paper presents a model for the genesis of De Geer moraines in the Chapais and Radisson areas, Québec. The model is mainly based on faciès and deformation structure analysis.

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.Abstract Nitrogen stable isotopes (δ15N) of ice core nitrate (NO3−) are often subject to diverse interpretations associated with changes in nitrogen oxide (NOx) sourcing, atmospheric reactions, and/or post‐depositional processes. Here, an ice core from Mont Blanc (French Alps) was analyzed to investigate the δ15N(NO3−) record over the past 1,000 years.

Recent structural evolution of Forni Glacier tongue (Ortles-Cevedale Group, Central Italian Alps)
Journal of Maps, 2017 Structural glaciology yields important details about the evolution of glacier dynamics in response to climate change. The maps provided here document the occurrence and evolution of brittle and ductile structures on the tongue of Forni Glacier, Ortles ...
