The irregular pattern of isotopic and ionic signals in the typical monsoon temperate-glacier area, Yulong mountain, China
Sampling was carried out at Baishui glacier No. 1, the largest glaciet on Yulong mountain, China, during the summers of 1999 and 2000, to investigate the spatial variations of oxygen isotopes in the atmosphere-glacier-river system. The results confirm that there is an apparent inverse relation betwe...
