Glaciological and geomorphological map of Glacier Noir and Glacier Blanc, French Alps [PDF]
Journal of Maps, 2015 This paper presents and describes a glaciological and geomorphological map of Glacier Noir and Glacier Blanc, French Alps. Glacier Noir is a debris-covered glacier and is adjacent to Glacier Blanc, a clean-ice (debris-free) glacier. The glaciological and geomorphological evolution of Glacier Blanc is well known, but the evolution of Glacier Noir is ...

Multi-sensor remote sensing to map glacier debris cover in the Greater Caucasus, Georgia
Journal of Glaciology, 2021 Global warming is causing glaciers in the Caucasus Mountains and around the world to lose mass at an accelerated pace. As a result of this rapid retreat, significant parts of the glacierized surface area can be covered with debris deposits, often making ...

Geochemical characterization of supraglacial debris via in situ and optical remote sensing methods: a case study in Khumbu Himalaya, Nepal [PDF]
The Cryosphere, 2012 Surface glacier debris samples and field spectra were collected from the ablation zones of Nepal Himalaya Ngozumpa and Khumbu glaciers in November and December 2009.

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.

Large-Scale Debris Cover Glacier Mapping Using Multisource Object-Based Image Analysis Approach
Remote Sensing, 2022 Large-scale debris cover glacier mapping can be efficiently conducted from high spatial resolution (HSR) remote sensing imagery using object-based image analysis (OBIA), which works on a group of pixels.

Including debris cover effects in a distributed model of glacier ablation [PDF]
, 2012 Distributed glacier melt models generally assume that the glacier surface consists of bare exposed ice and snow. In reality, many glaciers are wholly or partially covered in layers of debris that tend to suppress ablation rates.

The Problem of “Hidden” Ice in Glacier Mapping [PDF]
Annals of Glaciology, 1986 Ice can become “hidden”, i.e. buried, by the superimposition of rock debris on a glacier or where rock debris may incorporate interstitial ice. Because it is obscured, problems result from a lack of understanding of the extent and continued activity of such ice.

Air temperature distribution and energy balance modelling of a debris-covered glacier [PDF]
, 2016 Near-surface air temperature is an important determinant of the surface energy balance of glaciers that is often represented by constant linear temperature gradients in models.

Which glaciers are the largest in the world?
Journal of Glaciology, 2023 Glacier monitoring has been internationally coordinated for more than 125 years. Despite this long history, there is no authoritative answer to the popular question: ‘Which glaciers are the largest in the world?’ Here, we present the first systematic ...

Hydraulic impacts of glacier advance over a sediment bed [PDF]
, 2006 A sedimentary sequence of till overlying a gravel aquifer was instrumented with water-pressure transducers prior to a small, anticipated surge of the margin of the glacier Breiðamerkurjökull in Iceland.
