I see that you have received two excellent, justified, fair, constructive and partly detailed sets of referee comments. Likewise, I consider your responses to these comments sound, elaborated and promising. Regarding your request on an editorial perspective on adding further figures, I may note that I specifically asked the referees to pay attention to the indeed already impressive number of figures. Thus, I would advice the author team to make use of the possibility to move some of the figures to the Supplementary Information (SI), to first reduce the overall number of figures in the main text and second to potentially allow for the addition of a very small number of figures appearing in the author comments, if this is considered necessary. However, I would leave the first order decision on which figures to move to the SI to you as author(s) and, eventually, to the referees.

In conclusion, I believe this manuscript indeed touches a topic well in the scope of the journal, of timely relevance (as also acknowledged by both referees) and potentially impressive impact. I therefore ask you for a revised version of the material, according to the changes proposed in the online discussion and would then ask the referees for their evaluation f the updated manuscript.

All the best,


Michael Dietze

Dear Greg and colleagues,

According to the two referee evaluations of the revised version of the manuscript, I am delighted to accept the work for publication given that you account for (or argue against) the one minor issue that referee two mentioned:

"I accept, that it is difficult to normalize the sediment 10Be-records in a way, that amplitudes are preserved. However, for ice core data this is possible. In figures 18a and 22a, only ice core data is shown. Calculating zscores creates the odd artifact, that one wonders how the stack can be the average of (normalized) GRIP and GISP records but not match their amplitude. Please normalize all datsets to their mean. If you still want to show the data in zscores, the normalized records can subsequently standardized using the same mean and variance for all records."

I will evaluate the minor revisions as soon as I get them from the author team in due course, to get this manuscript finalised as soon as possible.

Kind regards,


Michael Dietze

Hi Greg and author team,

thanks for working with the Associate Editor Michael Dietze and his referees. I am happy to follow Michael’s suggestion and accept your manuscript for publication. I am confident that your comprehensive and detailed study will attract much attention.

Thank you for considering GChron,
Andreas
