Nine Centuries of Microparticle Deposition at the South Pole
Abstract The analysis of microparticles in a 101-m core from Amundsen-Scott South Pole Station, Antarctica has revealed a substantial increase in total particle concentration between approximately 1450 and 1850 A.D., a period encompassing the latest neoglacial interval or Little Ice Age. It is likel...
