Which institute has been studying the Pensilungpa Glacier in Zanskar, Ladakh, to monitor its retreat and mass balance?
Wadia Institute of Himalayan Geology (WIHG)
The Wadia Institute of Himalayan Geology (WIHG), Dehradun — an autonomous institute under the Department of Science and Technology — has been studying the Pensilungpa Glacier (PG) in the Zanskar region of Ladakh since 2015.
The institute monitors the glacier's retreat and mass balance through stake networks installed on the glacier's surface. Its findings, published in the journal Regional Environmental Change, attribute the glacier's recession (about 6.7 m per year between 2015 and 2019) to rising temperatures and decreased winter precipitation.
The other options deal with different domains: INCOIS — ocean information; CMFRI — marine fisheries; ZSI — fauna survey. None of them studies Himalayan glaciers.
Hence the correct answer is Wadia Institute of Himalayan Geology (WIHG).
