Many thanks for the revisions you brought to your manuscript, which, in my opinion, respond to all of the reviewers' minor comments and really improve its readability (and hopefully its impact). I appreciate in particular the care you have taken to re-organize parts of the manuscript to better separate observations/data from your interpretation. The introduction is also much improved and gives your work a better framework for the reader to appreciate it. Reading through the revised version of the manuscript, I note, however, that some of the references in the reference list are out of alphabetical order. I assume this very minor point is of technical nature and should not delay the publication of this manuscript any longer.

Dear Alison and co-authors,
I am happy to let you know that your manuscript has now been accepted for publication in ESurf. Associate editor Jean Braun advises that your manuscript is ready for publication after very minor editorial changes. Thank you once more for considering ESurf.
Best wishes,
Andreas Lang
