Abstract

A large volcanic sulfate increase observed in ice core records around 1450 C.E. has been attributed in previous studies to a volcanic eruption from the submarine Kuwae caldera in Vanuatu. Both EPMA-WDS (electron microprobe analysis using a wavelength dispersive spectrometer) and SEM-EDS (scanning el...
