Estimation of glacier dynamics of the major glaciers of Bhutan using geospatial techniques

Journal of Water and Climate Change, 2023
The purpose of this study was to determine the glacier displacement, velocity, and thickness of seven major glaciers of Bhutan and predicted potential glacier lake formation site with its depth.

Quasi-static granular flow of ice mélange [PDF]

, 2018
We use Landsat 8 imagery to generate ice mélange velocity fields at Greenland’s three most productive outlet glaciers: Jakobshavn Isbræ, Helheim Glacier, and Kangerdlugssuaq Glacier.

Present dynamics and future prognosis of a slowly surging glacier [PDF]

The Cryosphere, 2011
Glacier surges are a well-known example of an internal dynamic oscillation whose occurrence is not a direct response to the external climate forcing, but whose character (i.e.

Terminus change of Kaskawulsh Glacier, Yukon, under a warming climate: retreat, thinning, slowdown and modified proglacial lake geometry

Journal of Glaciology, 2023
Links between proglacial lakes and glacier dynamics are poorly understood but are necessary to predict how mountain glaciers will react to a warmer, wetter climate, where such lakes are expected to increase both in number and volume.

Future projection of cryospheric and hydrologic regimes in Koshi River basin, Central Himalaya, using coupled glacier dynamics and glacio-hydrological models

Journal of Glaciology, 2020
Climate-induced cryospheric changes can have a significant impact on the downstream water availability. In this study, the Open Global Glacier Model (OGGM) and the Glacio-hydrological Degree-day Model (GDM) are integrated to project the response of ...

Explaining mass balance and retreat dichotomies at Taku and Lemon Creek Glaciers, Alaska

Journal of Glaciology, 2020
We reanalyzed mass balance records at Taku and Lemon Creek Glaciers to better understand the relative roles of hypsometry, local climate and dynamics as mass balance drivers. Over the 1946–2018 period, the cumulative mass balances diverged.

Variability of Glacier Velocity and the Influencing Factors in the Muztag-Kongur Mountains, Eastern Pamir Plateau

Remote Sensing, 2023
Glacier velocity is the key to understanding the nature of glaciers. Its variation plays an important role in glacier dynamics, mass balance, and climate change.

Ice‐Dynamical Glacier Evolution Modeling—A Review

Reviews of Geophysics, 2022
AbstractGlaciers play a crucial role in the Earth System: they are important water suppliers to lower‐lying areas during hot and dry periods, and they are major contributors to the observed present‐day sea‐level rise. Glaciers can also act as a source of natural hazards and have a major touristic value.

Glacier retreat, dynamics and bed overdeepenings of Parkachik Glacier, Ladakh Himalaya, India

Annals of Glaciology, 2023
This study describes the morphological and dynamic changes of Parkachik Glacier, Suru River valley, Ladakh Himalaya, India. We used medium-resolution satellite images; CORONA KH-4, Landsat and Sentinel-2A from 1971–2021, and field surveys between 2015 ...

Fundamentals of glacier dynamics [PDF]

Geomorphology, 2001
Glaciers form when snow melts and refreezes, or is compressed, to form ice. Spreading under their own weight, they flow seaward, channeled along preferred routes by the shape or composition of the underlying bedrock. Though we don't know why, some ice streams flow rapidly within slower‐moving ice in Greenland and Antarctica.
