A dramatic 800-m retreat of a lake-terminating glacier on the Tibetan Plateau during 2014–2015, caused by glacier calving

Journal of Glaciology
Compared to land-terminating glaciers, lake-terminating glaciers generally experience a higher mass loss due to the feedback from processes such as calving, dynamic thinning and flow acceleration associated with proglacial lakes.

Surface dynamics and history of the calving cycle of Astrolabe Glacier (Adélie Coast, Antarctica) derived from satellite imagery [PDF]

The Cryosphere
The recent calving of Astrolabe Glacier on the Adélie Coast (East Antarctica) in November 2021 presents an opportunity to better understand the processes leading to ice tongue fracturing.

An energy-balance model for debris-covered glaciers including heat conduction through the debris layer [PDF]

, 2010
Extensive covers of supraglacial debris are often present in glacier ablation areas, and it is essential to assess exactly how the debris affects glacier melt rates.

Grounding Zone of Helheim Glacier, Greenland, From Terrestrial Radar Interferometry

Geophysical Research Letters
Helheim Glacier, in East Greenland, is a major outlet glacier that discharges about 33 Gigatons of ice per year into the ocean. Helheim has been undergoing a retreat since 2003.

Calving as a Source of Acute and Persistent Kinetic Energy to Enhance Submarine Melting of Tidewater Glaciers

Geophysical Research Letters
Calving icebergs at tidewater glaciers release large amounts of potential energy. This energy—in principle—could be a source for submarine melting, which scales with near‐terminus water temperature and velocity.

Modeling the Controls on the Front Position of a Tidewater Glacier in Svalbard

Frontiers in Earth Science, 2017
Calving is an important mass-loss process at ice sheet and marine-terminating glacier margins, but identifying and quantifying its principal driving mechanisms remains challenging.

The aftermath of Petermann Glacier calving events (2008-2012): Ice island size distributions and meltwater dispersal. [PDF]

, 2018
Three large calving events occurred at Petermann Glacier in northwest Greenland between 2008 and 2012 that generated ice islands (large tabular icebergs) that ranged from ~30 to 300 km2 in areal extent.

Tidewater calving

, 1996
Data from Columbia Glacier are used to identify processes that control calving from a temperate tidewater glacier and to re-evaluate models that have been proposed to describe iceberg calving.

Synchronous terminus change of East Antarctic outlet glaciers linked to climatic forcing [PDF]

, 2013
In recent years there has been a growing trend of acceleration, thinning and retreat of ocean-terminating outlet glaciers in both the Greenland and West Antarctic Ice Sheets, resulting in an increasing contribution to sea level rise.
