A data set of worldwide glacier length fluctuations [PDF]

open access: yesThe Cryosphere, 2014
Glacier fluctuations contribute to variations in sea level and historical glacier length fluctuations are natural indicators of past climate change. To study these subjects, long-term information of glacier change is needed.

Classifying disequilibrium of small mountain glaciers from patterns of surface elevation change distributions

open access: yesJournal of Glaciology, 2022
The overall trend of rapid retreat of Alpine glaciers contains considerable variability of responses at the scale of individual glaciers. As a step towards a regional assessment of glacier state that allows a detailed differentiation of single glaciers ...

A note on the snout

open access: yesJournal of Glaciology, 2023
The shallow ice approximation for glaciers and ice sheets is a degenerate model in which the ice surface slope at the margin may be infinite. This result is due to the neglect of the otherwise small longitudinal stress terms.

Spatio-temporal variability in geometry and geodetic mass balance of Jostedalsbreen ice cap, Norway

open access: yesAnnals of Glaciology, 2023
The Jostedalsbreen ice cap is mainland Europe's largest ice cap and accommodates 20% (458 km2 in 2019) of the total glacier area of mainland Norway.

Holocene glacier fluctuations

open access: yesQuaternary Science Reviews, 2015
A global overview of glacier advances and retreats (grouped by regions and by millennia) for the Holocene is compiled from previous studies. The reconstructions of glacier fluctuations are based on 1) mapping and dating moraines defined by ¹⁴C, TCN, OSL, lichenometry and tree rings (discontinuous records/time series), and 2) sediments from proglacial ...

Rapid glacial retreat on the Kamchatka Peninsula during the early 21st century [PDF]

open access: yesThe Cryosphere, 2016
Monitoring glacier fluctuations provides insights into changing glacial environments and recent climate change. The availability of satellite imagery offers the opportunity to view these changes for remote and inaccessible regions.

Projected sea-level contributions from tidewater glaciers are highly sensitive to chosen bedrock topography: a case study at Hansbreen, Svalbard

open access: yesJournal of Glaciology, 2023
Calculation of the calving loss of tidewater glaciers depends on accurate bedrock information. In regional to global-scale projections of future tidewater glacier evolution this dependence is problematic.

Precipitation as the main driver of Neoglacial fluctuations of Gualas glacier, Northern Patagonian Icefield [PDF]

open access: yesClimate of the Past, 2012
Glaciers are frequently used as indicators of climate change. However, the link between past glacier fluctuations and climate variability is still highly debated.

Transient evolution of basal drag during glacier slip

open access: yesJournal of Glaciology, 2022
Glacier slip is usually described using steady-state sliding laws that relate drag, slip velocity and effective pressure, but where subglacial conditions vary rapidly transient effects may influence slip dynamics.

A unified model for transient subglacial water pressure and basal sliding

open access: yesJournal of Glaciology, 2022
Changes in water pressure at the beds of glaciers greatly modify their sliding rate, affecting rates of ice mass loss and sea level change. However, there is still no agreement about the physics of subglacial sliding or how water affects it.
