A geochemical approach to reconstruct modern dust fluxes and sources to the South Pacific

Abstract We present the first comprehensive dust provenance and lithogenic flux data set extracted from surface sediments distributed across the polar and subpolar South Pacific. The dataset comprises 230Th-normalized lithogenic fluxes combined with rare earth elements, strontium, neodymium and lead isotope data to determine lithogenic fluxes, spatial distribution and sources of dust (
