CHEMICAL CHARACTERISTICS AND SALT ORIGIN OF THE WATER IN LAKE VANDA, WRIGHT VALLEY, SOUTHERN VICTORIA LAND, ANTARCTICA
Since the International Geophysical Year (1957-1958), a number of saline lakes have been found and studied in the Dry Valley region, southern Victoria Land, Antarctica. The water in Lake Vanda shows specific chemical characteristics of calcium-chloride type. Many ideas for the origin of salts in the...
