Evidence for an 11-year cycle of atmospheric H2O2 fluctuation recorded in an ice core at the coastal region, East Antarctica

Abstract

Hydrogen peroxide (H2O2) concentrations in an ice core obtained at site S25, near the coastal region on Mizuho Plateau, East Antarctica, have been determined. The time series of H2O2 concentrations showed not only seasonal variations, but also about 11-year variations corresponding to the solar cycle. There is a possibility that atmospheric H2O2 concentrations might have been associated with the solar cycle.
