Dear Michael,

Thanks for your response to both referees. I invite you to submit a revised version of your manuscript that account for the remarks and comments made in both reviews. Due to a number of points raised by both referees, I will then send back the revised version of your paper for a second round of review. Based on these new reviews I will take a final decision.

Best regards,
Olivier Gagliardini

Dear Michael,

Thanks for this new version of your paper, which has been send to one of the reviewer, who noticed that you convincingly answered all the points raised in the first round of review and were able to provide an improved version of your manuscript. Based on this last review, I am happy to accept your paper for publication in The Cryosphere. I have just noticed a typo that you should correct before sending the final version.

Thanks for having choosing The Cryosphere for publishing this nice piece of work!
Regards,
Olivier Gagliardini

technical corrections:
- second sentence in 4.3.4 looks strange ("sediment is not only exerts important", should be "sediment does not only exert important" or "sediment is not only exerting important"?)
