Glacier Velocity Changes in the Himalayas in Relation to Ice Mass Balance

open access: yesRemote Sensing, 2021
Glacier evolution with time provides important information about climate variability. Here, we investigated glacier velocity changes in the Himalayas and analysed the patterns of glacier flow.

Discovery of the Fastest Ice Flow along the Central Flow Line of Austre Lovénbreen, a Poly-thermal Valley Glacier in Svalbard

open access: yesRemote Sensing, 2019
Ice flow velocity is a sensitive indicator of glacier variations both controlling and representing the delivery of ice and affecting the future stability of ice masses in a warming climate.

Surface lowering of the debris-covered area of Kanchenjunga Glacier in the eastern Nepal Himalaya since 1975, as revealed by Hexagon KH-9 and ALOS satellite observations [PDF]

open access: yesThe Cryosphere, 2017
This study presents the geodetic mass balance of Kanchenjunga Glacier, one of the largest debris-covered glaciers in the easternmost Nepal Himalaya, which possesses a negative mass balance of −0.18 ± 0.17 m w.e.

Mapping Surface Flow Velocity of Glaciers at Regional Scale Using a Multiple Sensors Approach [PDF]

open access: yesRemote Sensing, 2019
We explore and compare the capabilities and limitations of different optical sensors (Sentinel-2/ESA, Landsat 7/8/USGS, Ven μ s/CNES-ISA, Pléiades/AirbusD&S and Planet Labs images) for mapping the surface speeds of mountain glaciers on a regional scale.

Investigating the Intra-Annual Dynamics of Kunlun Glacier in the West Kunlun Mountains, China, From Ascending and Descending Sentinel-1 SAR Observations

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Monitoring glacier dynamics is an effective approach for quantifying the response of the glaciers in cold arid mountainous areas to climate change. However, the quantification of short-term flow dynamics of the mountain glaciers in cold-dry climates has ...

Creep-Velocity Bounds and Glacier-Flow Problems [PDF]

open access: yesJournal of Glaciology, 1967
Abstract A general result due to Martin can be used to find upper and lower bounds on velocities in steady-creep problems. This method can be applied to glacier flow if ice can be assumed to satisfy a powerlaw stress–strain-rate relation.

Flow and structure in a dendritic glacier with bedrock steps

open access: yesJournal of Glaciology, 2017
We analyse ice flow and structural glaciology of Shackleton Glacier, a dendritic glacier with multiple icefalls in the Canadian Rockies. A major tributary-trunk junction allows us to investigate the potential of tributaries to alter trunk flow and ...

The dynamics of Trooz Glacier, Antarctic Peninsula, by satellite remote sensing data

open access: yesУкраїнський антарктичний журнал, 2023
The paper studies the ice cover of the Trooz Glacier, Kyiv Peninsula, West Antarctic Peninsula. The main goal of the work is to study the velocity dynamics of various parts of the Trooz Glacier in 2016–2022 based on remote sensing data and to compare ...

On the Secular Variation of Ice Flow Velocity at Lewis Glacier, Mount Kenya, Kenya [PDF]

open access: yesJournal of Glaciology, 1982
Abstract Measurements at various epochs in the course of the twentieth century indicate a slowing down of surface ice flow velocity. This is consistent with the numerical modeling of the secular glacier recession, which furthermore shows a gradual upward shift of the regions of highest velocity and mass flux.

ICE VELOCITY MEASUREMENT IN EAST ANTARCTICA FROM 1960s TO 1980s BASED ON ARGON AND LANDSAT IMAGERY [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
Ice flow velocity is a vital parameter for estimating the ice mass balance of glaciers in Antarctica. Especially long time serial observation of the surface velocity is of great significance to assessing the relationship between Antarctic ice materials ...
