Ice core evidence for the extent of past atmospheric CO₂ change due to iron fertilisation / R. Röthlisberger, M. Bigler, E.W. Wolff, F. Joos, E. Monnin, M.A. Hutterli.

Title: Ice core evidence for the extent of past atmospheric CO₂ change due to iron fertilisation / R. Röthlisberger, M. Bigler, E.W. Wolff, F. Joos, E. Monnin, M.A. Hutterli.

Abstract: Presents extended high-resolution ice core record of dust deposition over past 60 ka from Dome C, Antarctica, which conflicts with idea that changes in aeolian iron input into Southern Ocean were major cause for 80 ppm glacial-interglacial CO₂ increase. During deglaciation, CO₂ increase shows linear relationship with fall of logarithm of nss-Ca²⁺ flux, proxy for dust deposition. However, very large variations in nss-Ca²⁺ flux related to glacial Antarctic warm events A1 to A4 were accompanied by small CO₂ variations only. Data-based analysis suggests that decreased Southern Ocean dust deposition caused at most 20 ppm increase in CO₂ at last glacial-interglacial transition. Rapid decreases in dust deposition to northern Pacific could have been responsible for maximum of 8 ppm in addition.
