Dramatic loss of glacier accumulation area on the Tibetan Plateau revealed by ice core tritium and mercury records
Two ice cores were retrieved from high elevations (~5800 m a.s.l.) at Mt. Nyainqêntanglha and Mt. Geladaindong in the southern and central Tibetan Plateau region. The combined tracer analysis of tritium ( 3 H), 210 Pb and mercury, along with other chemical records, provided multiple lines of evidenc...
