As I know, palaeoclimatologists use benthic foraminifera oxygen isotope to reconstruct the ice volume. However, this contains both Arctic and Antarctica information. Shall we separate the signal? Thanks.
Yes,we shall. North and south polar regions have very different geographical conditions and palaegeographical history, so analitic data have different meaning
Following rapid rise during meltwater pulse 1a that started the Holocene (12-11 ka, lobal average sea level rose ~ 2 mm /yr from 10-5 ka, 0.75±0.25 mm/yr from 5-2 ka and has remained stable in the Common Era. Most of this from the ice sheets, though apportioning to West Antarctica vs. Laurentide is speculative.
Follow Gunter faure book...chapter on Oxygen Isotopes...the curve for evolutionary history of ice sheets in Holocene is given...
I agree with K.G. Miller that from 5 ka onwards ice sheets in both polar regions are stable.
