MINOR CHEMICAL CONSTITUENTS IN SNOW COVER ON MIZUHO PLATEAU, ANTARCTICA
A good correlation between chemical compositions of falling snow and atmospheric aerosols is needed to obtain information on the ancient global and atmospheric environment from chemical study of polar ice. For this purpose, atmospheric aerosols and snow were sampled by members of JARE-29 (1988-1989)...
