In the 1981-1982 austral summer, geochemical research was carried out at the Dry Valleys region of South Victoria Land, Antarctica. 48 kinds of water samples were collected from the Lake Vanda and Boney, Don Juan Pond and the Labyrinth area. Boron and chloride ion containing in lake or pond waters were determined with the methylene-blue absorptiometry and silver nitrate titration. Enrichment coefficients of boron were compared with the Copenhagen water. The values of those of lakes or ponds near the terminus of continental glacier were larger and far from the glacier were smaller.
