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 ...

An inventory of Norway's glaciers and ice-marginal lakes from 2018–19 Sentinel-2 data

Journal of Glaciology, 2022
We used Sentinel-2 satellite imagery at 10 m resolution to map the extent of Norway's glaciers and ice-marginal lakes over 2018–19. We applied a standardized semi-automated band ratio method to derive glacier outlines and ice-marginal lakes.

Reanalysis of long-term series of glaciological and geodetic mass balance for 10 Norwegian glaciers [PDF]

The Cryosphere, 2016
Glaciological and geodetic methods provide independent observations of glacier mass balance. The glaciological method measures the surface mass balance, on a seasonal or annual basis, whereas the geodetic method measures surface, internal, and basal mass

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 ...

Spatio-temporal variability in geometry and geodetic mass balance of Jostedalsbreen ice cap, Norway

Annals of Glaciology, 2023
The Jostedalsbreen ice cap is mainland Europe's largest ice cap and accommodates 20% (458 km2 in 2019) of the total glacier area of mainland Norway.

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.

Multivariate statistical analysis to assess the surface water quality of a snow and glacier-fed river: A case from Alaknanda River basin

Water Science and Technology, 2023
The water quality of Himalayan rivers has declined due to human activities, untreated effluent discharge, and poor sewage and drainage systems. The current study aimed to assess the water quality of these rivers using multivariate statistical analysis ...

Slow change since the Little Ice Age at a far northern glacier with the potential for system reorganization: Thores Glacier, northern Ellesmere Island, Canada

Arctic Science, 2023
Relatively little is known about the glaciers of northern Ellesmere Island, Canada. Here we describe the first field and remote sensing observations of Thores Glacier, located 50 km inland from the Arctic Ocean.

Unprecedented 21st century glacier loss on Mt. Hood, Oregon, USA [PDF]

The Cryosphere
As part of the southern Cascades, Mt. Hood is the tallest and most glacierized peak in Oregon, USA. Despite alpine glaciers being one the clearest indicators of human-caused climate change, the 21st century behavior of glaciers on Mt.
