Carstensz Glacier
Encyclopedia
The Carstensz Glacier is near the peak of Puncak Jaya
(sometimes called Mount Carstensz or the Carstensz Pyramid) which is a mountain in the Sudirman Range
, western central highlands of Papua province
, Indonesia
. The glacier is situated at an altitude of approximately 4600 metres (15,091.9 ft) and is 1.5 kilometre (0.93205910497471 mi) east of the summit tower of Puncak Jaya. The Carstensz Glacier is 1.4 kilometre (0.869921831309729 mi) in length and 0.6 kilometre (0.372823641989884 mi) wide.
Research presented in 2004 of IKONOS
satellite imagery
of the New Guinean glaciers indicated that in the two years from 2000 to 2002, the Carstensz Glacier had lost a further 6.8% of it's surface area. An expedition to the remaining glaciers on Puncak Jaya in 2010 discovered that the ice on the glaciers there is about 32 metres (105 ft) thick and thinning at a rate of 7 metres (23 ft) annually. At that rate, the remaining glaciers in the immediate region near Puncak Jaya are expected to last only to the year 2015.
The remaining remnant glaciers on Punkak Jaya were once part of an icecap that developed approximately 5,000 years ago. At least one previous icecap also existed in the region between 15,000 and 7,000 years ago, when it also apparently melted away and disappeared.
