Globally scalable glacier mapping by deep learning matches expert delineation accuracy. [PDF]
Nat CommunAccurate global glacier mapping is critical for understanding climate change impacts. Despite its importance, automated glacier mapping at a global scale remains largely unexplored. Here we address this gap and propose Glacier-VisionTransformer-U-Net (GlaViTU), a convolutional-transformer deep learning model, and five strategies for multitemporal ...

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

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.

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 ...

GlacierNet2: A Hybrid Multi-Model Learning Architecture for Alpine Glacier Mapping [PDF]
International Journal of Applied Earth Observation and
Geoinformation, 2022, 2022 In recent decades, climate change has significantly affected glacier dynamics, resulting in mass loss and an increased risk of glacier-related hazards including supraglacial and proglacial lake development, as well as catastrophic outburst flooding. Rapidly changing conditions dictate the need for continuous and detailed observations and analysis of ...

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.

Cryospheric Impacts on Volcano-Magmatic Systems
Frontiers in Earth Science, 2022 In contrast to water and air, ice is the most dynamic enveloping medium and unique environment for volcanic eruptions. While all three environments influence volcanic activity and eruption products, the cryospheric eruption environment is unique because:
