| Abstract | This study assimilates data from historical records (1857–1961/84), survey of India topographic maps, and a series of multispectral satellite data (1962–2014) for analyzing the shrinkage and dimensional changes of the Kolahoi glacier, Jammu and Kashmir, between 1857 and 2014. The composite results show that the glacier has receded by ∼3423 m (21.8 m/year) in the past 157 years. The historical records reveal that the glacier retreated by >1609 m from 1857 to 1909, 800 m from 1912 to 1961, and 210 m from 1961 to 1984. From 1962 to 2014 (52 years), we observed a retreat of 1014 ± 64 m (19.5 ± 1.1 m/year). We noted a marked disparity in the retreat rates of primary snout (PS) and secondary snout (SS) which was found to be 19.5 ± 1.1 m/year for PS and 11.34 ± 1.1 m/year for SS. Further, our investigations reveal that the changes in the length are accompanied by considerable changes in the area. The area of the glacier reduced from 14.46 ± 0.34 km2 (1962) to 11.28 ± 0.21 km2 (2014) amounting an overall deglaciation of 3.18 ± 0.34 km2 or 22.99 ± 2.3% in the past 52 years. Besides, the glacier has started degenerating at a much accelerated pace showing a deglaciation of 11.1 ± 1.9% and a recession rate of ~27.8 ± 3.2 m/year in just 14 years (2000–2014). These results warrant the detailed studies regarding various controlling factors, besides the climate change. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
