Autonomous detection of calving-related seismicity at Kronebreen, Svalbard [PDF]
The Cryosphere, 2012 We detect and cluster waveforms of seismic signals recorded close to the calving front of Kronebreen, Svalbard, to identify glacier-related seismic events and to investigate their relation to calving processes.

Calving localization at Helheim Glacier using multiple local seismic stations [PDF]
The Cryosphere, 2017 A multiple-station technique for localizing glacier calving events is applied to Helheim Glacier in southeastern Greenland. The difference in seismic-wave arrival times between each pairing of four local seismometers is used to generate a locus of ...

Calving at Ryder Glacier, Northern Greenland [PDF]
Journal of Geophysical Research: Earth Surface, 2021 AbstractRecent evidence has shown increasing mass loss from the Greenland ice sheet, with a general trend of accelerated mass losses extending northwards. However, different glaciers have been shown to respond differently to similar external forcings, constituting a problem for extrapolating and upscaling data. Specifically, whilst some outlet glaciers

Calving on tidewater glaciers amplified by submarine frontal melting [PDF]
The Cryosphere, 2013 While it has been shown repeatedly that ocean conditions exhibit an important control on the behaviour of grounded tidewater glaciers, modelling studies have focused largely on the effects of basal and surface melting.

Calving Induced Speedup of Petermann Glacier [PDF]
Journal of Geophysical Research: Earth Surface, 2019 This study assesses the response on ice dynamics of Petermann Glacier, a major outlet glacier in northern Greenland, to the 2012 and a possible future calving event. So far Petermann Glacier has been believed to be dynamically stable as another large calving event in 2010 had no significant impact on flow velocity or grounding line retreat.

Ablation from calving and surface melt at lake-terminating Bridge Glacier, British Columbia, 1984–2013 [PDF]
The Cryosphere, 2016 Bridge Glacier is a lake-calving glacier in the Coast Mountains of British Columbia and has retreated over 3.55 km since 1972. The majority of this retreat has occurred since 1991.

Viscoelastic analysis of Calving Glaciers [PDF]
Annals of Glaciology, 1980 Calving of floating ice shelves is studied by a viscoelastic finite-element analysis. The fan-shaped breaking-up of glaciers due to forces that cause bending on creeping ice is assumed to be axisymmetric. Bending may be due to geometry of the bcdrock, action of tides and waves, and imbalance (at the ice front) between the stress in the ice and the sea ...

Journal of Glaciology, 2021 Up to 30% of the current tidewater mass loss in Svalbard corresponds to frontal ablation through submarine melting and calving. We developed two-dimensional (2-D) glacier–line–plume and glacier–fjord circulation coupled models, both including subglacial ...

Calving glaciers and ice shelves [PDF]
Advances in Physics: X, 2018 Calving, or the release of icebergs from glaciers and floating ice shelves, is an important process transferring mass into the world’s oceans. Calving glaciers and ice sheets make a large contribution to sea-level rise, but large uncertainty remains about future ice sheet response to alternative carbon scenarios.

Monitoring Glacier Calving using Underwater Sound
The Cryosphere, 2023 Abstract. Climate shifts are particularly conspicuous in the Arctic. Satellite and terrestrial observations show significant increases in the melting and breakup of Arctic tidewater glaciers and their influence on sea level rise. Increasing melt rates are creating an urgency to better understand the link between atmospheric and oceanic conditions and ...
