Thank you for your thorough responses to the reviewers’ comments. Please go ahead and submit your revised manuscript. I have recommended an additional round of review to ensure your revised interpretation is satisfactory, since they gave such a thorough assessment of your paper and the wider implications of your interpretation.

With respect to colour bars on the figures, please refer to the guidance on the Cryosphere website (https://www.the-cryosphere.net/submission.html#figurestables): For maps and charts, please keep colour blindness in mind and avoid the parallel usage of green and red. For a list of colour scales that are illegible to a significant number of readers, please visit ColorBrewer 2.0 (https://colorbrewer2.org/#type=sequential&scheme=BuGn&n=3). You can use this tool to assess whether your choices (regardless of whether they are the ‘geophysics standard’ or not) are suitable for all of our audience. In particular, can the purple in Figure 6 be replaced, maybe with a deeper shade of red? I agree with both reviewers that the current scale in Figs 6 and 7 is tricky to interpret – having something in the blue spectrum (dark blue vs. purple) at opposing ends of the colour scale is confusing.

Thank you for your engagement with the review process, I look forward to reading the revised manuscript.
