Measurement of the Retreat of Qori Kalis Glacier in the Tropical Andes of Peru

چکیده

The extent and volume of the largest outlet glacier from the Quelccaya Ice Cap (14°S, 71°W, 5200 m a.s.l.) has been measured four times between 1963 and 1991, once by aerial and three times by terrestrial photogrammetry. Drastic and accelerating retreat of the terminus and decrease of ice volume have been documented. The rate of retreat was nearly three times as fast between 1983 and 1991 as between 1963 and 1978 and the rate of volume loss was about eight times as great. These results are consistent with the behavior of tropical glaciers in the Cordillera Blanca in Peru and in the Ruwenzori Mountains and on Mount Kenya in East Africa.

A 1500-year record of tropical precipitation in ice cores from the quelccaya ice cap, peru.

Two ice cores, covering 1500 years of climatic information, from the summit (5670 meters) of the tropical Quelccaya ice cap, in the Andes of southern Peru, provide information on general environmental conditions including droughts, volcanic activity, moisture sources, temperature, and glacier net balance. The net balance record reconstructed from these cores reflects major precipitation trends ...

Tropical climate change recorded by a glacier in the central Andes during the last decades of the twentieth century: Chacaltaya, Bolivia, 16 S

[1] The reasons for the accelerated glacier retreat observed since the early 1980s in the tropical Andes are analyzed based on the well-documented Chacaltaya glacier (Bolivia). Monthly mass balance measurements available over the entire 1991–2001 decade are interpreted in the light of a recent energy balance study performed on nearby Zongo glacier and further put into a larger-scale context by ...

Retreat of Tropical Glaciers in Colombia and Venezuela from 1984 to 2004 as Measured from ASTER and Landsat Images

Like glaciers throughout the world, tropical glaciers in the northern Andes have retreated during the last century. In this study, the retreat of Andean glaciers in Colombian and Venezuela has been mapped from Landsat and ASTER images acquired between 1984 and 2004. Glacier retreat has been mapped for three glaciated regions in Columbia, the Sierra Nevada de Santa Marta, the Sierra Nevada del C...

Current state of glaciers in the tropical Andes: a multi-century perspective on glacier evolution and climate change

The aim of this paper is to provide the community with a comprehensive overview of the studies of glaciers in the tropical Andes conducted in recent decades leading to the current status of the glaciers in the context of climate change. In terms of changes in surface area and length, we show that the glacier retreat in the tropical Andes over the last three decades is unprecedented since the ma...
