As a mass balancein glaciology the difference between mass inflow and mass loss of an ice body is called. The total mass gain or loss of a glacier, an ice cap or an ice sheet over a hydrological cycle - usually one year - is called the total mass balance. The specific mass balance is the change in mass over a period of time in relation to a point on the glacier. Usually the total mass balance is determined by integrating measured specific mass balance data distributed over the glacier area. By dividing the total mass balance by the area of the glacier, the mean specific mass balance is obtained, which enables the behavior of different glaciers to be compared. If the mass balance is positive over several years, a glacier will advance, if it is negative it will retreat. If a glacier is in equilibrium with the climate, its mass balance is balanced. -Go to Article …
