Delineation of Glacier Drainage Basins on Western Vatnajokull [PDF]
Annals of Glaciology, 1986 Three ice-drainage basins on western Vatnajökull have been delineated with the aid of the first available, accurate ice-surface maps. These basins drain ice towards the major river systems: Tungnaá, Sylgja, and Kaldakvísl, There seems to be an important difference in the location of ice-drainage basins and melt water-drainage basins for the rivers ...

Slight change of glaciers in the Pamir over the period 2000–2017
Arctic, Antarctic, and Alpine Research, 2022 Glaciers in the Pamir are the water tower of arid Central Asia, and more than 50 million people depend on meltwater from them. Many studies have reported glacier changes in the Pamir, but the glacier inventories employed in the previous investigations ...

Using L-band SAR coherence to delineate glacier extent
Canadian Journal of Remote Sensing, 2010 Significant retreat has been seen in many glaciers worldwide. With increasing concern about the impact of global warming, there has been a concerted effort to monitor ongoing change. Projects such as Global Land Ice Measurements from Space (GLIMS) rely on the contributions of institutions worldwide to update a global database of digital glacier ...

Delineation of a complexly dipping temperate glacier bed using short-pulse radar arrays [PDF]
Journal of Glaciology, 2000 AbstractWe have defined the complex bed topography for a section of a small temperate glacier using 50 MHz monostatic short-pulse radar data and a synthetic-aperture array-processing method. The data were collected on a 100 m by 340 m array grid in the upper stem of Gulkana Glacier, central Alaska, U.S.A.

Improving semi-automated glacier mapping with a multi-method approach: applications in central Asia [PDF]
The Cryosphere, 2015 Studies of glaciers generally require precise glacier outlines. Where these are not available, extensive manual digitization in a geographic information system (GIS) must be performed, as current algorithms struggle to delineate glacier areas with debris

Using a Web Map Service to map Little Ice Age glacier extents at regional scales
Annals of Glaciology, 2023 Extending the record of glacier area changes into the past improves our understanding of climate change impacts. Although analogue maps showing historic glacier extents are abundant, digital outlines from before the satellite era are sparse as the ...

Glacier inventory and recent glacier variations in the Andes of Chile, South America
Annals of Glaciology, 2017 The first satellite-derived inventory of glaciers and rock glaciers in Chile, created from Landsat TM/ETM+ images spanning between 2000 and 2003 using a semi-automated procedure, is presented in a single standardized format.

Comparison of multiple glacier inventories with a new inventory derived from high-resolution ALOS imagery in the Bhutan Himalaya [PDF]
The Cryosphere, 2016 Digital glacier inventories are invaluable data sets for revealing the characteristics of glacier distribution and for upscaling measurements from selected locations to entire mountain ranges.

The GAMDAM glacier inventory: a quality-controlled inventory of Asian glaciers [PDF]
The Cryosphere, 2015 We present a new glacier inventory for high-mountain Asia named "Glacier Area Mapping for Discharge from the Asian Mountains" (GAMDAM). Glacier outlines were delineated manually using 356 Landsat ETM+ scenes in 226 path-row sets from the period 1999–2003,
