Decadally averaged δ18O (1997 - 1000 A.D.)
In 1997, three ice cores were recovered from the Dasuopu glacier
(28°23'N, 85°43'E) with the use of an electromechanical
drill in dry holes. The first core (C1) was 159.9 m long and was
drilled at 7000 m above sea level (a.s.l.) down the flow line from
the top of the col, and two cores (C2 and C3), 149.2 and 167.7 m long,
respectively, were drilled to bedrock 100 m apart on the col at
7200 m a.s.l. Visible stratigraphy showed no hiatus features in
any of the cores.
All cores were analyzed over their entire lengths for oxygen isotopic
ratio (δ18O ), chemical composition, and
