Ice magnetization in the EPICA-Dome C ice core: implication for dust sources during glacial and interglacial periods
[1] 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 fou...
