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 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.

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 ...

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

Regional passive seismic monitoring reveals dynamic glacier activity on Spitsbergen, Svalbard [PDF]

open access: yesPolar Research, 2015
Dynamic glacier activity is increasingly observed through passive seismic monitoring. We analysed near-regional-scale seismicity on the Arctic archipelago of Svalbard to identify seismic icequake signals and to study their spatial–temporal distribution ...

Calving controlled by melt-under-cutting: detailed calving styles revealed through time-lapse observations

open access: yesAnnals of Glaciology, 2019
We present a highly detailed study of calving dynamics at Tunabreen, a tidewater glacier in Svalbard. A time-lapse camera was trained on the terminus and programmed to capture images every 3 seconds over a 28-hour period in August 2015, producing a ...

A three-dimensional calving model: numerical experiments on Johnsons Glacier, Livingston Island, Antarctica [PDF]

open access: yes, 2010
Calving from tidewater glaciers and ice shelves accounts for around half the mass loss from both polar ice sheets, yet the process is not well represented in prognostic models of ice dynamics.

CALVING DYNAMICS DERIVED FROM SATELLITE SAR DATA IN SUPPORT OF MASS BALANCE ESTIMATIONS IN LANGE GLACIER, ANTARCTICA [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
We present calving flux, calving rate, frontal retreat and volume change rate results in Lange Glacier from 2015 to 2017, including also velocity calculations in 2015, 2017 and 2018.
