Annual Research Expedition to Rikha Samba Glacier, 2016


The International Centre for Integrated Mountain Development (ICIMOD) and national partners of the Cryosphere Monitoring Programme (CMP), Kathmandu University (KU) and the Department of Hydrology and Meteorology, the Government of Nepal (DHM), conducted an expedition to Rikha Samba Glacier in the Hidden Valley, Lower Mustang, Nepal, as a part of the Cryosphere Initiative’s annual research expedition to Rikha Samba. 

The six expedition team members carried out annual glacier mass balance measurements, measured snow density, downloaded data and maintained the hydrological station. They collected snow samples for black carbon analysis, and maintained instruments to measure precipitation and temperature at different ice depths. Additionally, the glacier was surveyed in different altitudinal and cross-sectional profiles with a differential GPS to determine glacier surface elevation changes. The permanent dGPS base station was marked with a brass plate for more accurate surveys. The automatic weather station’s (AWS) sensors were brought back to ICIMOD for calibration because the station collapsed in February 2016.
