METHANESULFONATE AND NON-SEA-SALT SULFATE IN DRIFTING-SNOW FROM EAST QUEEN MAUD LAND, EAST ANTARCTICA
Drifting-snow samples were collected at Mizuho Station from February to September 1986 and along traverse routes in east Queen Maud Land, East Antarctica, from October 1986 to January 1987. The typical sampling interval was about once a week. Variability in the methanesulfonate (MSA) and non-sea-sal...
