On the Role of Buoyant Flexure in Glacier Calving [PDF]
Geophysical Research Letters, 2016 Abstract Interactions between glaciers and the ocean are key for understanding the dynamics of the cryosphere in the climate system. Here we investigate the role of hydrostatic forces in glacier calving. We develop a mathematical model to account for the elastic deformation of glaciers in response to three effects: (i) marine and lake‐

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 about future ice sheet response to alternative carbon scenarios.

Progress in Physical Geography, 2002
Based on a review of observations on different types of calving glaciers, a simple calving model is proposed. Glaciers that exist in a sufficiently cold climate can form floating ice shelves and ice tongues that typically do not extend beyond confinements such as lateral fjord walls or mountains, and ice rises. If the local climate exceeds the thermal

Calving Processes and the Dynamics of Calving Glaciers
Earth-Science Reviews, 2007Abstract Calving of icebergs is an important component of mass loss from the polar ice sheets and glaciers in many parts of the world. Calving rates can increase dramatically in response to increases in velocity and/or retreat of the glacier margin, with important implications for sea level change.

The Calving Glaciers of Southern South America
Global and Planetary Change, 1999Abstract Calving glaciers constitute a great majority of all glaciers in Patagonia and Tierra del Fuego, and are dynamically important elements of the southern South American icefields. Large numbers of tidewater glaciers calve into the Chilean fjords, and many outlet glaciers terminate in proglacial lakes.

Underwater Acoustic Signatures of Glacier Calving [PDF]
Geophysical Research Letters, 2015 AbstractClimate‐driven ice‐water interactions in the contact zone between marine‐terminating glaciers and the ocean surface show a dynamic and complex nature. Tidewater glaciers lose volume through the poorly understood process of calving. A detailed description of the mechanisms controlling the course of calving is essential for the reliable ...

A Major Ice-Calving Event at Tasman Glacier Terminus, Southern Alps, 22 February 2011
Journal of the Royal Society of New Zealand, 2017 Terminus calving of icebergs is a common mass-loss mechanism from water-terminating glaciers globally, including the lake-calving glaciers in New Zealand’s central Southern Alps.

Marine sedimentation at a calving glacier margin
Geological Society of America Bulletin, 2000A 2-month study at a subpolar, tidewater glacier was conducted at Anvers Island, Antarctic Peninsula (lat 64°S), to improve understanding of sedimentary processes and associated deposits in glacial marine settings. Data collected in the ice-proximal environment were (1) brash ice-size distribution and melt rates to assess sediment source and transport ...

A Material Point Method for Glacier Calving
2020<p>Glaciers calving ice into the ocean is predicted to significantly contribute to sea-level rise and will thus influence future climate. Although numerous factors that induce glacier calving have been identified and studied, it is still extremely challenging to develop a unified and continuum computational framework that ...

Glacier Terminus Morphology Informs Calving Style
Geophysical Research LettersTerminus change is a complex outcome of ice‐ocean boundary processes and poses challenges for ice sheet models due to inadequate calving laws, creating uncertainty in sea level change projections.
