Wintertime supraglacial lake drainage cascade triggers large‐scale ice flow response in Greenland

N Maier, JK Andersen, J Mouginot… - Geophysical …, 2023 - Wiley Online Library
Surface melt forces summertime ice‐flow accelerations on glaciers and ice sheets. Here, we
show that large meltwater‐forced accelerations also occur during wintertime in Greenland …

[HTML][HTML] On the Green's function emergence from interferometry of seismic wave fields generated in high-melt glaciers: implications for passive imaging and monitoring

A Sergeant, M Chmiel, F Lindner, F Walter… - The …, 2020 - tc.copernicus.org

Ice cliff dynamics of debris-covered Trakarding glacier in the Rolwaling region, Nepal Himalaya

Y Sato, K Fujita, H Inoue, S Sunako, A Sakai… - Frontiers in Earth …, 2021 - frontiersin.org
Ice cliffs can act as “hot spots” for melt on debris-covered glaciers and promote local glacier
mass loss. Repeat high-resolution remote-sensing data are therefore required to monitor the …

Ross Ice Shelf displacement and elastic plate waves induced by Whillans Ice Stream slip events

DA Wiens, RC Aster, AA Nyblade… - Geophysical …, 2024 - Wiley Online Library
Ice shelves are assumed to flow steadily from their grounding lines to the ice front. We report
the detection of ice‐propagating extensional Lamb (plate) waves accompanied by pulses of …

L Moreau, L Seydoux, J Weiss… - The Cryosphere …, 2022 - tc.copernicus.org
In the perspective of upcoming seasonally ice-free Arctic, understanding the dynamics of
sea ice in the changing climate is a major challenge in oceanography and climatology. In …

Toward the acoustic detection of two‐phase flow patterns and Helmholtz resonators in englacial drainage systems

EA Podolskiy - Geophysical Research Letters, 2020 - Wiley Online Library
Passive acoustic monitoring has revolutionized the characterization of industrial processes

Towards the systematic reconnaissance of seismic signals from glaciers and ice sheets–Part 2: Unsupervised learning for source process characterization

RB Latto, RJ Turner, AM Reading, S Cook… - The …, 2024 - tc.copernicus.org
Given the high number and diversity of events in a typical cryoseismic dataset, in particular
those recorded on ice sheet margins, it is desirable to use a semi-automated method of …

Environment‐modulated glacial seismicity near Dålk Glacier in East Antarctica revealed by deep clustering

Y Hu, Z Li, L Fu, X Liu - Journal of Geophysical Research …, 2024 - Wiley Online Library
Over the past decades, seismic monitoring has been increasingly used to track glacial
activities associated with ice loss. Many seismological studies focus on West Antarctica …

[HTML][HTML] Impacts of post-depositional processing on nitrate isotopes in the snow and the overlying atmosphere at Summit, Greenland
