Mass and volume changes of Langjökull ice cap, Iceland, ~1890 to 2009, deduced from old maps, satellite images and in situ mass balance measurements
International audience We describe the mass balance of Langjökull ice cap, Iceland, (∼920 km²), ∼190 km^3) during several time intervals of different climate conditions that span the 20th century until present. The elevation range of Langjökull is 460-1440 m a.s.l. with a zero mass balance equilibri...
