To 6500m a.s.l.. In September 1998, an 80.36m ice core was also recovered in accumulation zone of the East Rongbuk Glacier on the northern slope of Mount Everest. The ice core was dated by seasonal variations of δ〓O (measured by Mat-Plus gas isotopic mass spectrograph with precision of 0.5‰) and major ions (measured by DX-2010 ions chromatography with precision of ng/L), together with the references of β activity peaks. Annual net accumulation was reconstructed based on the dating and density profile of the ice core.
