Dear Horst

I am happy to accept your paper for TC. Congratulations and thanks for having chosen TC!

I haven't gone through your revised manuscript version in all detail as there were only minor revisions suggested by the referees and you provided a sound response. From the response letter it became not in all cases fully clear to me if you modified the manuscript in response. When preparing the final version, please make sure to consider all referee comments and your response somehow, even if only in summary, in the text as the readers might well have similar questions as the referees.

Please check until the proof reading stage if the reference to Howat et al. (TCD) has by then become a TC one.

TC encourages (not: demands) newly to add a Author Contribution statement. See http://www.the-cryosphere.net/submission/manuscript_preparation.html

Consider to make the center lines in Fig 5 thicker and the circle numbers larger.

Best

Andy
