A Thin Film Viscoplastic Theory for Calving Glaciers: Toward a Bound on the Calving Rate of Glaciers [PDF]

open access: yesJournal 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 ...

Large spatial variations in the flux balance along the front of a Greenland tidewater glacier [PDF]

open access: yesThe Cryosphere, 2019
The frontal flux balance of a medium-sized tidewater glacier in western Greenland in the summer is assessed by quantifying the individual components (ice flux, retreat, calving, and submarine melting) through a combination of data and models. Ice flux

Impact of tides on calving patterns at Kronebreen, Svalbard – insights from three-dimensional ice dynamical modelling [PDF]

open access: yesThe Cryosphere, 2023
Understanding calving processes and their controls is of importance for reducing uncertainty in sea level rise estimates. The impact of tidal fluctuations and frontal melt on calving patterns has been researched through both modelling and observational ...

Modelling the impact of submarine frontal melting and ice mélange on glacier dynamics [PDF]

open access: yesThe Cryosphere, 2015
Submarine melting of the calving face of tidewater glaciers and the mechanical back force applied by the ice mélange layer are two mechanisms generally proposed to explain seasonal variations at the calving front of tidewater glaciers.

The slow advance of a calving glacier: Hubbard Glacier, Alaska, U.S.A. [PDF]

open access: yesAnnals of Glaciology, 2003
AbstractHubbard Glacier is the largest tidewater glacier in North America. In contrast to most glaciers in Alaska and northwestern Canada, Hubbard Glacier thickened and advanced during the 20th century. This a typical behavior is an important example of how insensitive to climate a glacier can become during parts of the calving glacier cycle.

The future is Nye: an extension of the perfect plastic approximation to tidewater glaciers

open access: yesJournal of Glaciology, 2016
Accurate modeling of calving glaciers relies on knowledge of many processes (ice flow, surface/submarine melting, calving, mélange interaction) and glacier-specific factors (air temperature, ocean circulation, precipitation rate, glacier geometry) that ...

Subglacial discharge controls seasonal variations in the thermal structure of a glacial lake in Patagonia

open access: yesNature Communications, 2021
Thermal conditions and circulation near glacier fronts are important to understand the recent rapid retreat of calving glaciers. New observations from a glacial lake suggesting a feedback mechanism between atmospheric warming, glacier front melting and ...

The Imminent Calving Retreat of Taku Glacier

open access: yesEos, 2021
Long an anomaly among glaciers, advancing while most others shrank, Taku Glacier is starting to succumb to climate change, offering an unprecedented look at the onset of tidewater glacier retreat.

Buoyant calving and ice-contact lake evolution at Pasterze Glacier (Austria) in the period 1998–2019 [PDF]

open access: yesThe Cryosphere, 2021
Rapid growth of proglacial lakes in the current warming climate can pose significant outburst flood hazards, increase rates of ice mass loss, and alter the dynamic state of glaciers. We studied the nature and rate of proglacial lake evolution at Pasterze
