CH4 emissions from runoff water of Alaskan mountain glaciers [PDF]

Scientific Reports
Recent studies have observed high methane concentrations in runoff water and the ambient air at various glacier sites, including the Greenland Ice Sheet, the glacier forefield in Svalbard, and the ice cap in Iceland.

Mourning Glaciers: Animism Reconsidered through Ritual and Sensorial Relationships with Mountain Entities in the Alps

Humans, 2023
The transformation due to climate change of the high Alpine mountains is intensifying. A real disruption in the perception of this milieu and in the ways of interacting with it is ongoing, as evidenced by recent funeral ceremonies organised for ...

Semi-Automated Mapping of Complex-Terrain Mountain Glaciers by Integrating L-Band SAR Amplitude and Interferometric Coherence

Remote Sensing, 2022
Mapping the outlines of glaciers has primarily relied on the interpretation of satellite optical images. However, the accurate delineation of glaciers in complex terrain mountain regions remains challenging, mainly because the supraglacial debris-covered

Supervised Methods for Modeling Spatiotemporal Glacier Variations by Quantification of the Area and Terminus of Mountain Glaciers Using Remote Sensing

Algorithms, 2023
Glaciers are important indictors of climate change as changes in glaciers physical features such as their area is in response to measurable evidence of fluctuating climate factors such as temperature, precipitation, and CO2. Although a general retreat of

Mountain glacier extents at the Last Glacial Maximum [PDF]

Scientific Data
Mountain regions experienced repeated glacial expansions and retreats during the Quaternary, shaping landscapes, ecosystems, and regional climates. While numerous reconstructions exist for individual mountain glaciers, global geodatabases remain scarce ...

Sub-seasonal variability of supraglacial ice cliff melt rates and associated processes from time-lapse photogrammetry [PDF]

The Cryosphere, 2022
Melt from supraglacial ice cliffs is an important contributor to the mass loss of debris-covered glaciers. However, ice cliff contribution is difficult to quantify as they are highly dynamic features, and the paucity of observations of melt rates and ...

Recent contrasting behaviour of mountain glaciers across the European High Arctic revealed by ArcticDEM data [PDF]

The Cryosphere, 2022
Small land-terminating mountain glaciers are a widespread and important element of Arctic ecosystems, influencing local hydrology, microclimate, and ecology.

Controls on Ice Cliff Distribution and Characteristics on Debris‐Covered Glaciers

Geophysical Research Letters, 2023
Ice cliff distribution plays a major role in determining the melt of debris‐covered glaciers but its controls are largely unknown. We assembled a data set of 37,537 ice cliffs and determined their characteristics across 86 debris‐covered glaciers within ...

Review article: Earth's ice imbalance [PDF]

The Cryosphere, 2021
We combine satellite observations and numerical models to show that Earth lost 28 trillion tonnes of ice between 1994 and 2017. Arctic sea ice (7.6 trillion tonnes), Antarctic ice shelves (6.5 trillion tonnes), mountain glaciers (6.1 trillion tonnes ...

Multi-decadal monsoon characteristics and glacier response in High Mountain Asia

Environmental Research Letters, 2022
Glacier health across High Mountain Asia (HMA) is highly heterogeneous and strongly governed by regional climate, which is variably influenced by monsoon dynamics and the westerlies.
