Modeling of firn compaction for estimating ice-sheet mass change from observed ice-sheet elevation change
Annals of Glaciology
Changes in ice-sheet surface elevation are caused by a combination of ice-dynamic imbalance, ablation, temporal variations in accumulation rate, firn compaction and underlying bedrock motion. Thus, deriving the rate of ice-sheet mass change from measured surface elevation change requires information on the rate of firn compaction and bedrock motion, which do not involve changes in mass, and requires an appropriate firn density to associate with elevation changes induced by recent accumulationdoi:10.3189/172756411799096321 fatcat:u5eq63wjdfexncr6d5im6jot5m
