Subaqueous glacier mass losses are not accounted for by traditional geodetic mass balance calculations. Estimates based on proglacial lake volume changes revealed that the mass loss of glaciers terminating into lakes in the greater Himalaya during 2000−2020 was previously underestimated by approximately 6.5%, with the largest underestimation in the central Himalaya.
