抄録

Surface snows were daily sampled by a traverse team of Antarctic Walk Expedition from Patriot Hills (80°21' S, 81°36'W) west Antarctica, to South Pole (ca. 1, 080 km away) between November 1992 and January 1993. To study spatial- and temporal-variations in snow chemistry, surface and fallen snow samples were also taken daily at a base camp near Patriot Hills for the same period of the traverse trip. Sea-salts components (Na⁺, Cl^- and Mg²⁺) showed constantly lower concentration levels in higher inland and southern locations. Spatial variations of methanesulfonate (MSA) and SO₄^2- concentration levels showed nearly parallel and similar variations to sea-salts profiles but were still variable at inland locations. A comparison between the base camp and the traverse data set suggested an unique source-transportation process for NO₃^- in higher inland of Antarctica.
