Context for the Recent Massive Petermann Glacier Calving Event [PDF]
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]
Ocean 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 floating ice shelves and glacier tongues which fringe the Antarctic continent are important because they help buttress ice flow from the ice sheet interior.

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.

Two Calving Laws for Grounded Iceberg-Calving Glaciers (Abstract only) [PDF]
Prediction of the future retreat of Columbia Glacier, Alaska, required a calving law for the boundary condition at the terminus. Qualitative observations on the variations of all major iceberg-calving glaciers of Alaska suggest that calving is high whenever glaciers terminate in deep water, and greatly reduced whenever they ...

Horizontal visibility, rather than concealment cover, drove fawn bedsite use and predation risk. Greater field of view decreased the odds of coyote predation, likely by facilitated by early detection. As fawns transitioned from hiders to followers, they shifted from using dense overstory concealment to more open overstory that favored improved escape ...

A high-resolution calving front data product for marine-terminating glaciers in Svalbard [PDF]
The 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]
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]
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.

Abstract The long history of reindeer herding in Fennoscandia has shaped the mountain tundra by influencing its productivity, nutrient and carbon cycling and vegetation structure. By partly limiting shrub expansion, extensive reindeer grazing contributes to ecosystem resilience and helps mitigate climate change effects.
