Dear Dr Drews and co-authors,

Thank you for your detailed responses to the two reviewers of your paper. Both reviewers and I agree that the paper represents an excellent and worthy contribution to The Cryosphere, and I am pleased to tell you that I will certainly accept the paper subject to you now making some extremely minor edits that I have identified in my final proof-reading. I have marked these on the attached document.

Two small issues that I have not marked in the attached but also need consideration are:

Consistency of whether you use radio-wave/radiowave/radar-wave/radarwave throughout the manuscript, including in figure captions and figure axes.

Consistency of how you write firn air content / firn air-content / firn-air-content

I expect that attending to these minor edits will be a very quick job, and they are so minor that I do not require a detailed letter explaining their implementation.

I look forward to hearing back from you soon,

Yours sincerely,

Robert G. Bingham

Dear Dr. Drews and co-authors,

I am delighted now to accept your manuscript for publication in The Cryosphere.

Thank you for making the final few edits, but, more importantly, thank you in the first place for submitting a manuscript that both reviewers already considered to be an excellent contribution.

This marks the end of my editorial contribution to your paper, and you should from now on be liaising with the publications team on matters of typesetting and proofreading. Thank you again for submitting this excellent paper to The Cryosphere.

Yours sincerely,

Robert Bingham
