NON-SEA-SALT SULFATE AND NITRATE VARIATIONS IN THE S25 CORE, NEAR THE COASTAL REGION, EAST ANTARCTICA

元データ 国立極地研究所

概要

Non-sea-salt sulfate (nssSO_4^<2->) and nitrate (NO_3^-) data in the S25 core in the coastal region on Mizuho Plateau, East Antarctica, have been analyzed. Time series of nssSO_4^<2-> which is mainly derived from marine-biogenic sulfur (DMS), showed not only seasonal variations, but also 4-5 year and about 8 year variations. The result indicates that DMS emission and the transport process of nssSO_4^<2-> may be affected by the Antarctic Circumpolar Wave (ACW), whose initiation is probably associated with El Nino activity. The NO_3 concentrations in the S25 core presented about 11-year variations corresponding to the solar cycle.
