Holocene history of the Ullukam Glacier

open access: yesЛëд и снег, 2015
Using instrumental archives, aerial photographs, satellite images, old maps, descriptions of early explorers and old photographs we identified and mapped nine front positions of the Ullukam Glacier (SW slope of Elbrus) for the period from the end of XIX ...

Hydraulic impacts of glacier advance over a sediment bed [PDF]

open access: yes, 2006
A sedimentary sequence of till overlying a gravel aquifer was instrumented with water-pressure transducers prior to a small, anticipated surge of the margin of the glacier Breiðamerkurjökull in Iceland.

Glacier change in Norway since the 1960s – an overview of mass balance, area, length and surface elevation changes

open access: yesJournal of Glaciology, 2020
In this paper, we give an overview of changes in area, length, surface elevation and mass balance of glaciers in mainland Norway since the 1960s. Frontal advances have been recorded in all regions except the northernmost glaciers in Troms and Finnmark ...

InSAR observations of ice elevation and velocity fluctuations at the Flade Isblink ice cap, eastern North Greenland [PDF]

open access: yes, 2010
The 8500 km(2) Flade Isblink ice cap (FIIC) (81 degrees 15'N, 15 degrees 0'W) is the largest ice cap in Greenland. We use repeat-pass interferometric synthetic aperture radar (InSAR) techniques to investigate the form and flow of the FIIC.

Surge history and dynamics of Fisher Glacier, Yukon, 1948–2022

open access: yesJournal of Glaciology
Remotely sensed datasets indicate that Fisher Glacier underwent two surges since 1948: during approximately 1969–72 and 2013–16. These were characterized by an advanced terminus position (terminus-wide average advance 571 ± 143 m from 1963 to 1972 and ...

Mass balance of Trambau Glacier, Rolwaling region, Nepal Himalaya: in-situ observations, long-term reconstruction and mass-balance sensitivity

open access: yesJournal of Glaciology, 2019
We conducted a mass-balance study of debris-free Trambau Glacier in the Rolwaling region, Nepal Himalaya, which is accessible to 6000 m a.s.l., to better understand mass-balance processes and the effect of precipitation on these processes on high ...

Glacier inventory and recent glacier variations in the Andes of Chile, South America

open access: yesAnnals of Glaciology, 2017
The first satellite-derived inventory of glaciers and rock glaciers in Chile, created from Landsat TM/ETM+ images spanning between 2000 and 2003 using a semi-automated procedure, is presented in a single standardized format.

Including debris cover effects in a distributed model of glacier ablation [PDF]

open access: yes, 2012
Distributed glacier melt models generally assume that the glacier surface consists of bare exposed ice and snow. In reality, many glaciers are wholly or partially covered in layers of debris that tend to suppress ablation rates.

Experimental constraints on transient glacier slip with ice-bed separation

open access: yesJournal of Glaciology
Fast glacier motion is facilitated by slip at the ice-bed interface. For slip over rigid beds, areas of ice-bed separation (cavities) can exert significant control on slip dynamics.

Intra-annual and intra-seasonal flow dynamics of a High Arctic polythermal valley glacier [PDF]

open access: yes, 2002
Measurements of surface dynamics on polythermal John Evans Glacier, Nunavut, Canada, over two winter periods and every 7-10 days throughout two melt seasons (June-July 2000, 2001) provide new insight into spatio-temporal patterns of High Arctic glacier ...
