A Model for Sedimentation by Tidewater Glaciers [PDF]

Annals of Glaciology, 1981
Sampling of sediment from the fjord floor in front of tidewater glaciers in Glacier Bay, Alaska, has provided information about processes in this restricted glacimarine (Dreimanis 1979) setting. Sediment sampling, in conjunction with oceanographic and glacial dynamics data, has also enabled the discrimination of sediment types and their facies ...

Calving rates at tidewater glaciers vary strongly with ocean temperature [PDF]

, 2015
TerraSAR-X data were provided by DLR (project OCE1503), and funded by the Conoco Phillips-Lundin Northern Area Program through the CRIOS project (Calving Rates and Impact on Sea level). A.L. and S.B.

On non-dimensional forms of basal sliding laws and flow laws for ice-sheet and glacier modelling

Journal of Glaciology
Ice sheets and glaciers flow through basal sliding and internal deformation, each governed by physical laws commonly expressed as power-law relations. These formulations include coefficients—the sliding coefficient and rate factor—whose values and units ...

Ecological interactions in glacier environments: a review of studies on a model Alpine glacier

Biological Reviews
ABSTRACTGlaciers host a variety of cold‐adapted taxa, many of which have not yet been described. Interactions among glacier organisms are even less clear. Understanding ecological interactions is crucial to unravelling the functioning of glacier ecosystems, particularly in light of current glacier retreat.

Glacier thickness estimations of alpine glaciers using data and modeling constraints [PDF]

The Cryosphere, 2019
Abstract. Advanced knowledge of the ice thickness distribution within glaciers is of fundamental importance for several purposes, such as water resource management and the study of the impact of climate change. Ice thicknesses can be modeled using ice surface features, but the resulting models can be prone to considerable uncertainties.

Numerical modelling of glacial lake outburst floods using physically based dam-breach models [PDF]

, 2015
The instability of moraine-dammed proglacial lakes creates the potential for catastrophic glacial lake outburst floods (GLOFs) in high-mountain regions.

Long-wavelength Pol-InSAR for glacier ice extinction estimation

, 2010
In recent years there has been increased interest in using synthetic aperture radar (SAR) to study and monitor glaciers for climate change research.

Meteorology and surface energy fluxes in the 2005–2007 ablation seasons at the Miage debris-covered glacier, Mont Blanc Massif, Italian Alps

, 2010
During the 2005–2007 June–September ablation seasons, meteorological conditions were recorded on the lower and upper parts of the debris‐covered ablation zone of Miage Glacier, Italy. In 2005, debris temperature and subdebris ice melt were also monitored

Changing snow cover and the net mass balance of Storglaciaren, northern Sweden [PDF]

, 2008
The spatial and temporal variability of seasonal snow cover in glacierized catchments has important implications for the net mass balance of alpine glaciers.

Modelling Dynamics of Valley Glaciers

, 2012
Ever since the Paleoproterozoic snowball Earth era, ca. 2.4 billion years ago (e.g. Hoffman & Schrag, 2000; Kirschvink, 1992), and beyond, the landscape of the planet Earth has been shaped up by the tremendous amount of scouring due to the repeated waxing and waning of ice masses.
