Modeling 2m air temperatures over mountain glaciers: Exploring the influence of katabatic cooling and external warming [PDF]

, 2015
Air temperature is one of the most relevant input variables for snow and ice melt calculations. However, local meteorological conditions, complex topography, and logistical concerns in glacierized regions make the measuring and modeling of air ...

Climate change and its relation to the fluctuation in glacier mass balance in the Cordillera Blanca, Peru: A review

Acta Universitatis Carolinae Geographica, 2018
This review article describes the main probable causes of glacier fluctuations in the Cordillera Blanca since the end of the Little Ice Age. The Cordillera Blanca glaciers reached their last maximum extent during the Little Ice Age and have been ...

The Red Rock ice cliff revisited – six decades of frontal, mass and area changes in the Nunatarssuaq area, Northwest Greenland

Journal of Glaciology, 2020
We present changes of the ice margin in Northwest Greenland at the Eastern part of the Nunatarssuaq Ice Cap (NIC) over six decades. The ice margin in this area terminates as a near-vertical ice cliff of between 9 and 33 m thickness. During the years 1954–

Debris cover and surface melt at a temperate maritime alpine glacier: Franz Josef Glacier, New Zealand [PDF]

, 2012
Melt rates on glaciers are strongly influenced by the presence of supraglacial debris, which can either enhance or reduce ablation relative to bare ice.

Glacier fluctuations in the Alps and in the tropical Andes

Comptes Rendus. Géoscience, 2004
This paper reports on glacier variations in two mountainous regions of the world, the Alps and the tropical Andes. Available records of snout position and glacier mass balance are compared and interpreted on a climatological basis. In both regions, there is a long-term decreasing trend over the 20th century.

Sustained retreat of the Pine Island Glacier [PDF]

, 2013
We use satellite observations to show that, between 1992 and 2011, the Pine Island Glacier hinge line retreated at a rate of 0.95 ± 0.09 km yr−1 despite a progressive steepening and shoaling of the glacier surface and bedrock slopes, respectively, which ...

Assessing glacier retreat and landform production at the ‘debris-charged’ snout of Kvíárjökull, Iceland [PDF]

, 2010
Iceland is a critical location for the study of glacier fluctuations and landform production in response to climate change due to its diverse glacial legacy and its archive of aerial photographs that provide accurately dated records of glacier retreat ...

A physically based calving model applied to marine outlet glaciers and implications for the glacier dynamics [PDF]

, 2010
We present results from numerical ice-flow models that include calving criteria based on penetration of surface and basal crevasses, which in turn is a function of longitudinal strain rates near the glacier front.

Crevasses triggered on Pine Island Glacier by drilling through an exceptional melt layer [PDF]

, 2010
The basic theory of crevasse formation suggests that crevasses initiate at or near the surface. However, due to variations in stress with depth, it has been suggested that it is possible for crevasses to initiate at depths of 10–30m.

Advance and thickening of the tidewater outlet glacier Eqalorutsit Kangilliit Sermiat surrounded by the thinning southern Greenland ice sheet

Journal of Glaciology
Although most Greenland glaciers have undergone thinning and frontal retreat in recent decades, the tidewater glacier Eqalorutsit Kangilliit Sermiat in South Greenland departs from this regional pattern.
