equilibrium line
Quick Summary
The equilibrium line is the elevation on a glacier where the accumulation of snow and ice equals the amount lost through melting and sublimation. This line is crucial for understanding a glacier's mass balance, which determines whether the glacier is growing or shrinking.
On a glacier, the area above the equilibrium line is the accumulation zone, where snow builds up. Below this line is the ablation zone, where ice melts or sublimates. The position of the equilibrium line can vary significantly due to factors like latitude, altitude, and local climate conditions. For instance, glaciers in maritime environments with heavy snowfall may have lower equilibrium lines than those in drier, continental climates. Changes in the equilibrium line's altitude over time can indicate shifts in climate patterns.123
