Using a Web Map Service to map Little Ice Age glacier extents at regional scales

open access: yesAnnals 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

open access: yesAnnals 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]

open access: yesThe 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]

open access: yesThe 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,

Response of glacier flow and structure to proglacial lake development and climate at Fjallsjökull, south-east Iceland

open access: yesJournal of Glaciology, 2019
Over recent decades, the number of outlet glaciers terminating in lakes in Iceland has increased in line with climate warming. The mass-balance changes of these lake-terminating outlet glaciers are sensitive to rising air temperatures, due to altered ...

Glacier Boundary Mapping Using Deep Learning Classification over Bara Shigri Glacier in Western Himalayas

open access: yesSustainability, 2022
Glacier, snow, and ice are the essential components of the Himalayan cryosphere and provide a sustainable water source for different applications. Continuous and accurate monitoring of glaciers allows the forecasting analysis of natural hazards and water

An automatic approach to delineate the cold–temperate transition surface with ground-penetrating radar on polythermal glaciers [PDF]

open access: yesAnnals of Glaciology, 2014
AbstractGround-penetrating radar has been widely used to map the thermal structure of polythermal glaciers. Hitherto, the cold–temperate transition surface (CTS) in radargrams has been identified by a labour-intensive and subjective manual picking method. We introduce a new automatic approach for picking the CTS that uses the difference in signal power

Deriving a year 2000 glacier inventory for New Zealand from the existing 2016 inventory

open access: yesAnnals of Glaciology, 2023
Due to adverse snow and cloud conditions, only a few inventories are available for the maritime glaciers in New Zealand. These are difficult to compare as different approaches and baseline data have been used to create them.

Image classification of marine-terminating outlet glaciers in Greenland using deep learning methods [PDF]

open access: yesThe Cryosphere, 2021
A wealth of research has focused on elucidating the key controls on mass loss from the Greenland and Antarctic ice sheets in response to climate forcing, specifically in relation to the drivers of marine-terminating outlet glacier change.
