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.

此外，笔者还参加了1998年9月东绒布冰川80.36m冰芯的钻取工作。1999-2000年，在实验室内对上述样品进行了δ〓O测量(在中科院寒区旱区环境与工程研究所冰芯与寒区环境开放研究实验室用Mat-Plus气体稳定同位素质谱仪测量，以δ〓O平均值为-20.05‰的希夏邦马峰地区大气降水作为标准水，测量精度为0.5‰)、主要可溶性阴阳离子浓度的测定(在美国新罕布什尔大学气候变化研究中心进行，测试仪器为DX-2010型离子色谱仪，其测量精度可达ng/L)以及β活化度的测量(在美国新罕布什尔大学气候变化研究中心进行)，并以此为基础尝试重建了该冰芯的年代和净积累量。
