This picture of Batura Glacier, within the higher Hunza Valley, within the Gilgit-Baltistan area of Pakistan, was captured on August 13, 2021, by the Copernicus Sentinel-2 mission. Credit score: Comprises modified Copernicus Sentinel information (2021), processed by ESA, one of many largest and longest glaciers on this planet, exterior of the polar areas
The Copernicus Sentinel-2 mission takes us over Batura Glacier – one of many largest and longest glaciers on this planet, exterior of the polar areas.
Positioned within the higher Hunza Valley, within the Gilgit-Baltistan area of Pakistan, the Batura Glacier is seen within the centre of the picture and is roughly 57 km lengthy. It flows from west to east and feeds the Hunza River in north Pakistan, then joins the Gilgit and Naltar Rivers earlier than it flows into the Indus River.
The decrease parts of the Batura Glacier function a gray sea of rocks and gravelly moraine (an accumulation of rocks and sediment carried down by the glacier usually attributable to avalanches). The glacier has a imply ice thickness of round 150 m, with the decrease components of the glacier holding most of its mass.
This false-color composite picture makes use of the near-infrared channel of the Copernicus Sentinel-2 mission to focus on vegetation, which seems in purple. Batura is bordered by a number of villages and pastures with herds of sheep, goats and cows the place roses and juniper bushes are fairly frequent. Within the upper-right of the picture, pockets of cultivated vegetation alongside the Gilgit and Hunza rivers might be noticed.
Batura Glacier is situated simply north of the Batura Muztagh, a sub-range of the Karakoram mountain vary, which incorporates the massifs of the Batura Sar, the twenty fifth highest mountain on Earth standing at 7795 m, and Passu Sar at 7478 m.
Glacier shrinkage is a outstanding signal of ongoing local weather change. Nevertheless, not like many glaciers around the globe, the glaciers residing within the mountain ranges in Karakoram should not responding to international warming. Their retreating is lower than the worldwide common, and in some circumstances, are both secure or rising. This anomalous conduct of the area’s glaciers has been coined the ‘Karakoram Anomaly’.
Scientists sometimes measure the motions of glaciers with ground-based measurements. Due to the rugged terrain and challenges concerned in subject research, long-term floor observational information on Karakoram is sparse. Satellites may also help monitor modifications in glacier mass, extents, hint space, and size of glacier modifications by time and derive floor velocity. Watch this video to be taught extra about how Copernicus Sentinel-2 may also help improve glacier monitoring.
