Earth System Science Data, 2022 . Exact information on the calving front positions of marine- or lake-terminating glaciers is a fundamental glacier variable for analyzing ongoing glacier change processes and assessing other variables like frontal ablation rates.

How to Get the Most Out of U-Net for Glacier Calving Front Segmentation
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 The melting of ice sheets and glaciers is one of the main contributors to global sea-level rise. Hence, continuous monitoring of glacier changes and in particular the mapping of positional changes of their calving front is of significant importance. This

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.

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 ...

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 ...

IEEE Transactions on Geoscience and Remote Sensing, 2021 Changes in the calving front position of marine-terminating glaciers strongly influence the mass balance of glaciers, ice caps, and ice sheets. At present, quantification of frontal position change primarily relies on time-consuming and subjective manual

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.

Quasi-static granular flow of ice mélange [PDF]
, 1936 We use Landsat 8 imagery to generate ice mélange velocity fields at Greenland’s three most productive outlet glaciers: Jakobshavn Isbræ, Helheim Glacier, and Kangerdlugssuaq Glacier.

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.
