First in situ record of decadal glacier mass balance (2003–2014) from the Bhutan Himalaya
This study presents the first decadal mass-balance record of a small debris-free glacier in the Bhutan Himalaya, where few in situ measurements have been reported to date. Since 2003 we have measured the mass balance of Gangju La glacier, which covers an area of 0.3km2 and extends from 4900 to 5200m...

This study presents the first decadal mass-balance record of a small debris-free glacier in the Bhutan Himalaya, where few in situ measurements have been reported to date.

The observed mass balance ranged from –1.12 to –2.04mw.e. a–1 between 2003 and 2014.
