accumulation
1. The input of ice to a glacier. Observations from the Decade glacier, Baffin Island, suggest that accumulation is greatest in shaded upland areas. The accumulation zone , or accumulation sub‐system , is that part of a glacier between the firn line and the source where the input of snow, firn, and ice exceeds losses by ablation . The lower limit of the accumulation zone is at the equilibrium line .

2. The reinvestment of surplus value, in the form of capital, in order to increase that capital. Accumulation is a key feature of capitalism because, in order to remain in ...
