Dear Trevor,

I'd like to thank you for such a thorough and detailed response to the reviewer comments. I note that there is some disagreement about one or two points, but it is clear that you have considered the comments in full and, even where there is disagreement, you can see a need to further justify and explain your approach (e.g. in relation to the modelling). This will strengthen the revised manuscript, which will likely to go back out to a single reviewer.

Best wishes,

Chris

Dear Trevor,

Thank you for submitting your revised manuscript to the Cryosphere. It is clear that you have taken on board the constructive comments of the two referees and have addressed most of their points. As is customary when both referees recommend major revisions, I will be sending the revised manuscript back out to review.

Best wishes,

Chris Stokes

Dear Trevor,

I'd like to thank you again for such a thoughtful and clear response to the reviewer comments. I sent the revised manuscript back to one of the original reviewers who was very impressed and has no further comments. Based on this and my own reading of the manuscript, I'd delighted to recommend publication. Thank you for submitting this manuscript to The Cryosphere.

Kind regards,

Chris Stokes
