Journal of Glaciology, 2023 We investigate the physical basis of the crevasse-depth (CD) calving law by analysing relationships between glaciological stresses and calving behaviour at Sermeq Kujalleq (Store Glacier), Greenland.

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.

Deriving mass balance and calving variations from reanalysis data and sparse observations, Glaciar San Rafael, northern Patagonia, 1950–2005 [PDF]
The Cryosphere, 2011 Mass balance variations of Glaciar San Rafael, the northernmost tidewater glacier in the Southern Hemisphere, are reconstructed over the period 1950–2005 using NCEP-NCAR reanalysis climate data together with sparse, local historical observations of air ...

Journal of Glaciology, 2022 Marine-terminating glaciers lose mass through melting and iceberg calving, and we find that meltwater drainage systems influence calving timing at Helheim Glacier, a tidewater glacier in East Greenland.

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.

Nanoimprinted Infrared Metasurface Multispectral Filters for Neural-Network-Assisted Low-Temperature Sensing. [PDF]
NanophotonicsNanoimprinted ring‐aperture filters turn weak infrared radiation into four geometrically tuned spectral inputs. Array‐period control places broad, overlapping bands with peak transmittance near 80%. Neural‐network calibration retrieves −20°C to 20°C blackbody temperatures with a mean absolute error of 0.160°C, approximately 63% below a single ...

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.

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.

A Thin Film Viscoplastic Theory for Calving Glaciers: Toward a Bound on the Calving Rate of Glaciers [PDF]
Journal of Geophysical Research: Earth Surface, 2019 Projections of the growth and demise of ice sheets and glaciers require physical models of the processes governing flow and fracture of ice. The flow of glacier ice has been treated using increasingly sophisticated models. By contrast, fracture, the process ultimately responsible for half of the mass lost from ice sheets through iceberg calving, is ...

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 ...
