摘要：Four Japanese geoscientists visited the Dry Valleys region to carry out geophysical and geochemical research programs for a period from December 1981 to January 1982. The main research subjects were;1) geochemical studies on fresh and saline lakes, 2) geophysical study of water temperature of Lake Vanda, 3) distribution of organic matters in the sediments and lake waters, 4) mercury determination in air, soils, sediments, algae and mosses, and distribution of evaporites in the region.
