Iron (Fe) concentrations and fluxes in TALDICE ice core 0.6 to 314 ky BP - Vallelonga, Paul; Barbante, Carlo; Cozzi, Giulio; Gabrieli, J; Schüpbach, Simon; Spolaor, Andrea; Turetta, C
Atmospheric fluxes of iron (Fe) over the past 200 kyr are reported for the coastal Antarctic Talos Dome ice core, based on acid leachable Fe concentrations. Fluxes of Fe to Talos Dome were consistently greater than those at Dome C, with the greatest difference observed during interglacial climates. We observe different Fe flux trends at Dome C and Talos Dome during the deglaciation and early Holocene, attributed to a combination of deglacial activation of dust sources local to Talos Dome and the reorganisation of atmospheric transport pathways with the retreat of the Ross Sea ice shelf. This supports similar findings...
