Ice magnetization in the EPICA-Dome C ice core: implication for dust sources during glacial and interglacial periods.
Isothermal remanent magnetization and insoluble dust content of ice samples from EPICA-Dome C ice core were measured to characterize the magnetic properties of atmospheric dust. Despite the larger concentration of dust aerosol during glacial stages, the magnetization of the dust fraction was found t...
