Context for the Recent Massive Petermann Glacier Calving Event [PDF]
Eos, Transactions American Geophysical Union, 2011 On 4 August 2010, about one fifth of the floating ice tongue of Petermann Glacier (also known as “Petermann Gletscher”) in northwestern Greenland calved (Figure 1). The resulting “ice island” had an area approximately 4 times that of Manhattan Island (about 253±17 square kilometers).

Disentangling the oceanic drivers behind the post-2000 retreat of Sermeq Kujalleq, Greenland (Jakobshavn Isbræ) [PDF]
The CryosphereOcean temperatures have warmed in the fjords surrounding the Greenland Ice Sheet, causing increased melt along their ice fronts and rapid glacier retreat and contributing to rising global sea levels.

Simultaneous disintegration of outlet glaciers in Porpoise Bay (Wilkes Land), East Antarctica, driven by sea ice break-up [PDF]
The Cryosphere, 2017 The floating ice shelves and glacier tongues which fringe the Antarctic continent are important because they help buttress ice flow from the ice sheet interior.

Journal of the Japanese Society of Snow and Ice, 2002 氷河のカービング(calving)は,末端が流出する水域が海か湖(真水)かによって,そのメカニズムや動的特性が異なる.カービングを支配する要素は,氷河の形態,動的状態,水深,底面地形,水文環境(融水の滲透,潮汐,潮流,波浪,対流等),大気および水との熱交換と多岐にわたる.山岳氷河のカービングの基礎的なしくみと特性について解説する.

Calving speed and climatic sensitivity of New Zealand lake-calving glaciers [PDF]
Annals of Glaciology, 2003 AbstractCalving speeds and calving mechanisms in fresh water contrast with those in tidewater. We obtained calving speeds for six lake-calving glaciers in New Zealand’s Southern Alps, and surveyed the depths and temperatures of their ice-contact lakes. The glaciers are temperate, grounded in shallow (≤20 m) water, and exhibit compressive flow at their ...

Integrative Zoology, EarlyView.The graphical abstract illustrates the comprehensive workflow of our study, from the deployment of infrared cameras at sites with high activity of four large carnivores, through data collection and assessment of activity patterns, to the prediction of time periods with potential human–large carnivore conflicts and the proposal of corresponding ...

A high-resolution calving front data product for marine-terminating glaciers in Svalbard [PDF]
Earth System Science DataThe mass loss of glaciers outside the polar ice sheets has been accelerating during the past several decades and has been contributing to global sea-level rise. However, many of the mechanisms of this mass loss process are not well understood, especially

Contribution of calving to frontal ablation quantified from seismic and hydroacoustic observations calibrated with lidar volume measurements [PDF]
The Cryosphere, 2019 Frontal ablation contributes significantly to the mass balance of tidewater glaciers in Svalbard and can be recovered with high temporal resolution using continuous seismic records.

An Intensive Observation of Calving at Helheim Glacier, East Greenland [PDF]
Oceanography, 2016 Calving of glacial ice into the ocean from the Greenland Ice Sheet is an important component of global sea level rise. The calving process itself is relatively poorly observed, understood, and modeled; as such, it represents a bottleneck in improving future global sea level estimates in climate models.

Boreas, EarlyView.We present a 25‐stage reconstruction of the ice‐flow pattern evolution of the Scandinavian Ice Sheet based on mapping and analysis of ~240 000 subglacial lineations and lineation fields across Norway, Sweden, Finland, and parts of NW Russia. Our reconstruction uses a glacial geomorphological inversion approach, in which we generated 611 individual ...
