The accumulation area decreased by 24.8 %, while ablation area increased by 17.7 % with nearly 6 % increase in debris - cover surface in ablation zone in 1958 to 2011. (chimalaya.org)
The darker this ablation zone is, the more of the sun's energy it absorbs, and the faster the ice melts. (sciencedaily.com)
In effect, this UAV survey across the ablation zone of the ice sheet perfectly bridges the gap between people on the ground studying what's under their feet in just one part of the ice sheet, and the satellite data that shows what's going on across the entire ice sheet. (sciencedaily.com)
