Abashiri is a rural city on Hokkaido Island, Japan. It lies directly to the south of the Okhotsk Sea, which is the lowest latitude sea to freeze. We collected daily deposition samples over two periods: from Jan. 1997 to Mar. 1998, and from Nov. 1998 to Mar. 1999. The average concentrations of anthropogenic chemical species (non-seasalt(nss)-) were relatively low and those of seasalt species (Na+, Cl-, Mg2+) were high Japanese precipitation samples. During the period of study, we found that, when sea ice forms and approaches the coast, concentrations of seasalt species become lower, while almost no changes are found in the anthropogenic chemical species.
