High-altitude research station Himansh opens in Himachal

The National Centre for Antarctic and Ocean Research (NCAOR), Goa, a research organisation under the ministry of earth sciences, has established a high altitude research station in Himalachal called `Himnash' (literally meaning, a slice of ice), in Spiti, Himachal Pradesh, to better study and quantify the responses of Himalayan glaciers to climate change.

Situated above 13,500 ft (more than 4,000 metres) at a remote region in Spiti, Himachal Pradesh, the station was unveiled on Sunday 9 October 2016.

The station houses specialised instruments to quantify glacial melt and its relation to changing climate.

These include, automatic weather stations for weather monitoring, water level recorder for quantifying the glacier melt, ground penetrating radar to know the thickness of glaciers, geodetic GPS systems to study the glacier movements, snow fork for studying snow thickness, steam drill, snow corer, temperature profilers, as well as various glaciological tools.

Researchers would be using this as a base for undertaking surveys using terrestrial laser scanners (TLS) and unmanned aerial vehicles (UAV) that would digitise the glacier motion and snow cover variations with exceptional precision.

These initiatives would contribute to the integrated study of glaciers in the upper Indus basin (Chandra basin) in Himachal Pradesh and their contribution to discharge of water. According to the UN data, the contribution of snow / glacier melt in annual stream runoff is substantially higher (over 40 per cent) in the Indus basin as compared to Ganga and Brahmaputra basins (less than 10 per cent).

Therefore, understanding the glacier mass balance and their contribution to the Indus River is more critical than other basins towards understanding the impact of glacier retreat on the water cycle in the northern India and Pakistan.

Some of the bench mark glaciers that are already being studied under this project include Bada Shigri, Samudra Tapu, Sutri Dhaka, Batal, Gepang Gath and Kunzam. An integrated study using glaciological, geodetic, glacio-hydrological methods will shed light on the glacier response to the changing climate in this region and will also quantify the contribution from glacial melt water to the river discharge in Indus basin. ''Himansh'' will provide the much needed fillip to the scientific research on Himalayan glaciers and its hydrological contribution, says an official release.

Himalayan region has the largest concentration of glaciers outside the polar caps, as this region is aptly called the `Water Tower of Asia' is the source of the 10 major river systems that provide irrigation, power and drinking water for over 700 million people live in India, Pakistan and Bangladesh– nearly 10 per cent of the world's population. Understanding the behaviour of these glaciers and their contribution to the sustainable supply of water for mankind and agriculture is one of the grand challenges of Indian scientific community, the release added.
