Glacier accumulation and ablation AntarcticGlaciers.org . Most glaciers receive more inputs and accumulation in their upper reaches, and lose more mass by ablation in their lower reaches. The Equilibrium Line Altitude (ELA) marks the area of the glacier separating the accumulation zone from the ablation zone, and were annual accumulation and ablation are. Ver mais

WebAccumulation and ablation vary in space and time. In any particular location on a glacier’s surface mass may accumulate at one time of year and ablate at another. The net accumulation (accumulation minus ablation) summed over a specific time period, is.
