Figure 3

Recent 3 Myr history of surface forcing temperature (top surface) for the QEIG in comparison with previous model for Richard Island/Mallik. Ground surface temperatures are −6°C in Mallik and −20°C in QEIG at present. Two models were considered for the Mallik area, beside the 14 Myr long “cold” model also the “warm” model starting 3 Myr ago at 0°C and decreasing linearly to −10°C at 0.9 Myr ago.
