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.

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 ...

Hydrological controls on diurnal ice flow variability in valley glaciers [PDF]

, 2005
This paper uses a combination of field data and three-dimensional modeling to investigate the spatial variability in basal conditions required to induce observed fluctuations in diurnal ice velocity at Haut Glacier d'Arolla, Switzerland.

Glacio-limnological interactions at lake-calving glaciers [PDF]

, 2012
Iceberg calving is an efficient ablation process which introduces mechanical instability to glacier systems and can cause non-linear climatic response.

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 ...

Response of a marine-terminating Greenland outlet glacier to abrupt cooling 8200 and 9300 years ago [PDF]

, 2011
Long-term records of Greenland outlet-glacier change extending beyond the satellite era can inform future predictions of Greenland Ice Sheet behavior. Of particular relevance is elucidating the Greenland Ice Sheet's response to decadal- and centennial ...

Recent glacier decline in the Kerguelen Islands (49°S, 69°E) derived from modeling, field observations, and satellite data [PDF]

, 2015
Date of Acceptance: 28/02/2015The retreat of glaciers in the Kerguelen Islands (49°S, 69°E) and their associated climatic causes have been analyzed using field data and Moderate Resolution Imaging Spectroradiometer (MODIS) satellite images to validate a ...

Neue Ergebnisse zur Gletscher- und Klimageschichte des Spätmittelalters und der Neuzeit [PDF]

Geographica Helvetica
This article contributes to the glacier and climatic fluctuations during the late Middle Ages and the Modern Times. With the aid of radiocarbon dating of fossil woods and a fossil soil (fAh) located in the gletschervorfeld of two glaciers (Glacier de ...

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.

Subglacial drainage processes at a High Arctic polythermal valley glacier [PDF]

, 2005
Dye-tracer experiments undertaken over two summer melt seasons at polythermal John Evans Glacier, Ellesmere Island, Canada, were designed to investigate the character of the subglacial drainage system and its evolution over a melt season. In both summers,
