Glacier Image Velocimetry: an open-source toolbox for easy and rapid calculation of high-resolution glacier velocity fields [PDF]

The Cryosphere, 2021
We present Glacier Image Velocimetry (GIV), an open-source and easy-to-use software toolkit for rapidly calculating high-spatial-resolution glacier velocity fields.

Steep ice – progress and future challenges in research on ice cliffs

Annals of Glaciology, 2022
Ice cliffs are features along ice sheet margins, along tropical mountain glaciers, at termini of mountain glaciers and on debris-covered glacier tongues, that have received scattered attention in literature.

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 ...

Mass balance and area changes of glaciers in the Cordillera Real and Tres Cruces, Bolivia, between 2000 and 2016

Journal of Glaciology, 2020
Climate change has led to a significant shrinkage of glaciers in the Tropical Andes during the last decades. Recent multi-temporal quantifications of ice mass loss at mountain range to regional scale are missing.

Glaciological Investigations of the Tropical Quelccaya Ice Cap, Peru [PDF]

Journal of Glaciology, 1980
AbstractGlaciological results of the continuing investigations of the Quelccaya ice cap located at lat. 13° 56’ S., long. 70° 50’ W., in the Cordillera Oriental of southern Peru are presented. Ice cores to a depth of 15 m have been retrieved from the summit dome (5650 m), middle dome (5543 m), and south dome (5480 m) and sampled in detail for ...

Improved estimates of glacier change rates at Nevado Coropuna Ice Cap, Peru

Journal of Glaciology, 2018
Accurate quantification of rates of glacier mass loss is critical for managing water resources and for assessing hazards at ice-clad volcanoes, especially in arid regions like southern Peru.

Glacier mass balance of tropical Zongo glacier, Bolivia, comparing hydrological and glaciological methods

Global and Planetary Change, 2007
Abstract A glaciological program has been undertaken since 1991 on Zongo glacier in Bolivia (6000–4850 m asl, 2.4 km2, 16°S). This program involves mass balance measurements, hydrological studies and energy balance investigations. On outer-tropical glaciers, melting and snow accumulation are both maximum in the wet season (austral summer), whereas ...

Importance of longwave emissions from adjacent terrain on patterns of tropical glacier melt and recession

Journal of Glaciology, 2018
Tropical glaciers constitute an important source of water for downstream populations. However, our understanding of glacial melt processes is still limited.

Energy balance analysis of a tropical glacier in the Andes and identification of key meteorological variables for empirical melt estimates

Annals of Glaciology
This study investigated surface energy fluxes of the Huayna-Potosí Glacier in Bolivia to validate existing empirical melt estimates, including degree-day models and enhanced temperature-index models.

A geophysical and glaciological survey of the highest tropical mountain glaciers (Mt. Huascarán, Andes)

Journal of Glaciology
Abstract Peru hosts a significant portion of the world’s tropical glaciers, which are undergoing rapid mass loss due to climate change. Knowledge of the ice volume and bedrock topography of these glaciers is important for predicting changes in glacier dynamics, runoff, and interpreting ice-core records. This study presents results from glaciological
