Isotopic Study on Saline Lakes in Antarctica
In order to understand the origin of saline lakes in the southern Victoria Land, Soya Coast, and Vestfold Hills, the hydrogen and oxygen isotopic ratios of lake waters were measured. The relationship between the two isotopic ratios in these lakes shifted from that of meteoric water in the direction...
