Journal 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.

Helheim Glacier diurnal velocity fluctuations driven by surface melt forcing
Journal of Glaciology, 2021 The influence of surface melt on the flow of Greenland's largest outlet glaciers remains poorly known and in situ observations are few. We use field observations to link surface meltwater forcing to glacier-wide diurnal velocity variations on East ...

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

Palaeogeography, Palaeoclimatology, Palaeoecology, 2020 A suite of limnological proxies measured in clastic sediments of the glacier-fed Lake Ala Kol (NE Kyrgyzstan) document palaeoenvironmental change and glacier fluctuations in the central Tian Shan over the last millennium.

Transient evolution of basal drag during glacier slip
Journal 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
Journal 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.

Glacier shrinkage across High Mountain Asia
Annals of Glaciology, 2016 An assessment of glacier shrinkage (reduction of area) for all of High Mountain Asia requires a complete compilation of measured rates of change and also a methodology for objective comparison of rates.

Modelling and climatic interpretation of the length fluctuations of Glaciar Frías (north Patagonian Andes, Argentina) 1639–2009 AD [PDF]
Climate of the Past, 2012 We explore the climatic information contained in the record of length fluctuations of Glaciar Frías, in the north Patagonian Andes of Argentina. This record is one of the longest and most detailed glacier records in southern South America, starting in ...

The response of glaciers to climatic persistence
Journal of Glaciology, 2016 The attribution of past glacier length fluctuations to changes in climate requires characterizing glacier mass-balance variability. Observational records, which are relatively short, are consistent with random fluctuations uncorrelated in time, plus an ...

Testing the consistency between changes in simulated climate and Alpine glacier length over the past millennium [PDF]
Climate of the Past, 2018 It is standard to compare climate model results covering the past millennium and reconstructions based on various archives in order to test the ability of models to reproduce the observed climate variability.
