Progress toward globally complete frontal ablation estimates of marine-terminating glaciers
peer reviewed Knowledge of frontal ablation from marine-terminating glaciers (i.e., mass lost at the calving face) is critical for constraining glacier mass balance, improving projections of mass change, and identifying the processes that govern frontal mass loss. Here, we discuss the challenges inv...
