Tensile strength of glacial ice deduced from observations of the 2015 eastern Skaftá cauldron collapse, Vatnajökull ice cap, Iceland

Journal of Glaciology, 2020
The representation of iceberg calving in numerical models is a key source of uncertainty in century-scale sea-level rise projections. Parameters central to model representations of calving, including the tensile strength of glacier ice, remain poorly ...

Analysis of the Image of Global Glacier Tourism Destinations from the Perspective of Tourists

Land, 2022
Glaciers are attracting increasing attention in the context of climate change, and glacier tourism has also become a popular tourist product. However, few studies have been conducted concerning the image of glacier tourism destinations.

What Can We Learn from Comparing Glacio-Hydrological Models?

Atmosphere, 2020
Glacio-hydrological models combine both glacier and catchment hydrology modeling and are used to assess the hydrological response of high-mountain glacierized catchments to climate change. To capture the uncertainties from these model combinations, it is

A new global dataset of mountain glacier centerlines and lengths [PDF]

Earth System Science Data, 2022
The length of a glacier is a key determinant of its geometry and is an important parameter in glacier inventories and modeling; glacier centerlines are the lines along which the main flow of glaciers takes place and, thus, are crucial inputs for many ...

Mutual effects of ablation and ice temperature in a firn-free glacier: Observations from Aug 1st glacier on northeast Tibetan plateau. [PDF]

iScience
Summary: Glacier stability depends on the interaction between ice temperature and ablation, processes mediated by firn cover. Although firn-covered glaciers have been extensively investigated, firn-free glacier dynamics remain less clear.

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.

Contrasts in the response of adjacent fjords and glaciers to ice-sheet surface melt in West Greenland

Annals of Glaciology, 2016
Neighboring tidewater glaciers often exhibit asynchronous dynamic behavior, despite relatively uniform regional atmospheric and oceanic forcings. This variability may be controlled by a combination of local factors, including glacier and fjord geometry ...

Ocean forcing drives glacier retreat in Greenland

Science Advances, 2021
Many Greenland glaciers have been attacked by the ocean from below and, in turn, contributed to sea-level rise from the ice sheet. The retreat and acceleration of Greenland glaciers since the mid-1990s have been attributed to the enhanced intrusion of ...

Stable water isotope modeling reveals spatio-temporal variability of glacier meltwater contributions to Ganges River headwaters

Journal of Hydrology, 2019
Himalayan headwater rivers are sourced from glacier meltwater and from Indian summer monsoon (ISM) precipitation, both of which are strongly influenced by ongoing and future climate change.

Glacier-Surface Velocity Derived Ice Volume and Retreat Assessment in the Dhauliganga Basin, Central Himalaya – A Remote Sensing and Modeling Based Approach

Frontiers in Earth Science, 2019
Himalayan glaciers are a storehouse of fresh water and play a significant role in influencing the runoff through numerous perennial rivers flowing over the Indo-Gangetic plains, providing freshwater to the second largest populated country in the world ...
