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 ...

Efficient Location and Extraction of the Iceberg Calved Areas of the Antarctic Ice Shelves [PDF]
Remote Sensing, 2020 Continuous, rapid, and precise monitoring of calving events contributes to an in-depth understanding of calving mechanisms, which have the potential to cause significant mass loss from the Antarctic ice sheet.

Wave erosion, frontal bending, and calving at Ross Ice Shelf [PDF]
The CryosphereIce shelf calving constitutes roughly half of the total mass loss from the Antarctic ice sheet. Although much attention is paid to calving of giant tabular icebergs, these events are relatively rare.

The ice dynamic and melting response of Pine Island Ice Shelf to calving [PDF]
Annals of Glaciology, 2022 Sea level rise contributions from Pine Island Glacier (PIG) are strongly modulated by the backstress that its floating extension – Pine Island Ice Shelf (PIIS) – exerts on the adjoining grounded ice. The front of PIIS has recently retreated significantly via calving, and satellite and theoretical analyses have suggested further retreat is inevitable ...

Evaluation of four calving laws for Antarctic ice shelves [PDF]
The Cryosphere, 2023 Many floating ice shelves in Antarctica buttress the ice streams feeding them, thereby reducing the discharge of icebergs into the ocean. The rate at which ice shelves calve icebergs and how fast they flow determine whether they advance, retreat, or ...

The Energy Balance of Calved Ice in Lake Jökulsarlon, Iceland [PDF]
Arctic, Antarctic, and Alpine Research, 2003 Abstract We describe energy fluxes involved in melting ice in the proglacial lake Jokulsarlon and the transport of thermal energy into the lake from the atmosphere and the sea. Data from earlier fieldwork and campaigns have been used to estimate the net radiation balance, the turbulent fluxes, the heat provided by inflowing seawater, and the glacial ...

Viscous and elastic buoyancy stresses as drivers of ice-shelf calving [PDF]
Journal of Glaciology, 2020 The Antarctic Ice Sheet loses mass via its ice shelves predominantly through two processes: basal melting and iceberg calving. Iceberg calving is episodic and infrequent, and not well parameterized in ice-sheet models.

Bending Shear: The Rate-controlling Mechanism for Calving Ice Walls [PDF]
Journal of Glaciology, 1989 AbstractBending shear was observed to produce nearly vertical shear bands in a calving ice wall standing on dry land on Deception Island (lat. 63.0°S., long. 60.6 W.), and slabs calved straight downward when shear rupture occurred along these shear bands (Hughes, 1989). A formula for the calving rate was developed from the Deception Island data, and we

The instantaneous impact of calving and thinning on the Larsen C Ice Shelf [PDF]
The Cryosphere, 2022 The Antarctic Peninsula has seen rapid and widespread changes in the extent of its ice shelves in recent decades, including the collapse of the Larsen A and B ice shelves in 1995 and 2002, respectively.

Modelled fracture and calving on the Totten Ice Shelf [PDF]
The Cryosphere, 2018 Abstract. The Totten Ice Shelf (IS) has a large drainage basin, much of which is grounded below sea level, leaving the glacier vulnerable to retreat through the Marine Ice Shelf Instability mechanism. The ice shelf has also been shown to be sensitive to changes in calving rate, as a very small retreat of the calving front from its current position is ...
