Underwater acoustic signatures of glacier calving [PDF]

open access: yesGeophysical 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 ...

On the role of buoyant flexure in glacier calving [PDF]

open access: yesGeophysical Research Letters, 2016
AbstractInteractions 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‐terminating ...

Calving Induced Speedup of Petermann Glacier [PDF]

open access: yesJournal of Geophysical Research: Earth Surface, 2019
This study assesses the response on ice dynamics of Petermann Glacier, a major outlet glacier in northern Greenland, to the 2012 and a possible future calving event. So far Petermann Glacier has been believed to be dynamically stable as another large calving event in 2010 had no significant impact on flow velocity or grounding line retreat.

Glacier Terminus Morphology Informs Calving Style

open access: yesGeophysical Research Letters
AbstractTerminus 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. To address this, we quantify glacier termini sinuosity and convexity, testing the hypothesis that terminus morphology reflects dominant calving ...

Modelling environmental influences on calving at Helheim Glacier in eastern Greenland [PDF]

open access: yesThe Cryosphere, 2014
Calving is an important mass-loss process for many glaciers worldwide, and has been assumed to respond to a variety of environmental influences. We present a grounded, flowline tidewater glacier model using a physically-based calving mechanism, applied ...

Detection of Glacier Calving Margins with Convolutional Neural Networks: A Case Study

open access: yesRemote Sensing, 2019
The continuous and precise mapping of glacier calving fronts is essential for monitoring and understanding rapid glacier changes in Antarctica and Greenland, which have the potential for significant sea level rise within the current century.

Tidewater glacier response to individual calving events

open access: yesJournal of Glaciology, 2022
AbstractTidewater glaciers have been observed to experience instantaneous, stepwise increases in velocity during iceberg-calving events due to a loss of resistive stresses. These changes in stress can potentially impact tidewater glacier stability by promoting additional calving and affecting the viscous delivery of ice to the terminus.

Glacier Calving Rates Due to Subglacial Discharge, Fjord Circulation, and Free Convection

open access: yesJournal of Geophysical Research F: Earth Surface, 2018
Tidewater glacier calving provides the most direct mechanism of ice transfer from land to the ocean. However, the physical melt processes influencing calving remain challenging to constrain.

Surface wave generation due to glacier calving

open access: yesOceanologia, 2013
Coastal glaciers reach the ocean in a spectacular process called "calving". Immediately after calving, the impulsive surface waves are generated, sometimes of large height.

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.
