Dear Dr. Inoue,

Please revise the manuscript, addressing all the Reviewer comments.

Best regards,

Kumiko

1. As R1 commented, I also believe that an accumulation record would add to the manuscript, however I would leave it to the authors to decide.
2. R1 pointed out that the accumulation value on p. 5 line 12 (1,312 kg/m2yr, Roberts et al., 2013) was somewhat different from the one in Table 1 (1.35 mIE/yr). I think this is fine, because they are the results from two different studies. But I agree with R1 that the units should be the same.
3. Fig. 1. The full map in the lower right corner is not large enough that one can see the area marked with red. Please consider making the small map of all Antarctica bigger and make red boundary thicker. Also the red star with the position of the ice core is very small. Please make it larger.
4. Ion data which are not discussed in the text. Section 2.3 states the measurement of K, Mg and Ca. But neither of K and Ca are stated in the text thereafter. Please remove them from Section 2.3 or explain them in the text. As for Mg, the data are shown in Figs. 4 and 5, but not discussed in the text. Please remove the Mg data from Figs. 4 and 5, or discuss about Mg in the text. If the authors decide to remove Mg from Section2.3, Fig. 4 and Fig. 5, please remove it from P. 13, L. 10 as well.
5. P. 4, L. 25. Pro-gram’s. Is this correct? Or do you mean Program’s?
6. P. 5, L. 1-L. 2 and L. 24-L. 26. Please state exactly which volcanic makers were used. Please also mark them in Fig. 4.
7. P. 5, L. 33. “e.g. Na…… has a summer peak”. This needs references.
8. P. 6, L. 6-L.8. Please state how the months were defined.
9. P. 6. Line 18 states that “the Na winter peak during regime A is not present in regime B”, whilst Line 32 states that “Na and SO4 both show seasonality with a winter peak in Regimes A and B.” Please slightly modify these sentences to avoid contradiction.
