The annual mass balance of a glacier is a hydrologic budget measuring the difference between the amounts of accumulation and ablation experienced by a glacier during the hydrologic year (Knight, 1999). Depending on the quantity of annual accumulation and ablation; the mass balance value may be positive, negative, or zero. Glacier mass balance is a good measure of the general health of a glacier. A positive mass balance indicates mass accumulation and that the glacier is growing; conversely, a negative balance indicates that the glacier is shrinking. A glacier with a mass balance of zero is in a steady-state and has a constant volume.
