Mass-balance changes of the debris-covered glaciers in the Langtang Himal, Nepal, from 1974 to 1999
Thick debris cover on glaciers can significantly reduce ice melt. However, several studies have suggested that debris-covered glaciers in the Himalaya might have lost mass at a rate similar to debris-free glaciers. We reconstruct elevation and mass changes for the debris-covered glaciers of the uppe...
