Dear André Löfgren and co-authors,

Based on your in-depth rebuttal and the actions that you outline in order to address the reviewers comments, I invite you to submit a revised manuscript. I especially appreciate the many clarifications in the methodological details, the additional experiments (steady state, glacier retreat, mesh size, mesh consistency, …) as well as that you recalled to address my concerns from the initial access review.

Considering the higher-order time discretisation and the evaluation against a manufactured solution, you provide arguments to not address them during this revision step. As these were major comments of the reviewers, I suggest that the revised manuscript undergoes a second evaluation round by the reviewers.

All the best,

The editor

Johannes Fürst

Dear André Löfgren and co-authors,

Both reviewers appreciate the changes that you have implemented in response to their initial concerns. Also both do recommend publication. Yet reviewer #2 raises some final technical/copy-edit corrections. Please follow these advices.

Apart from these corrections, I am most delighted to inform you that I decided to forward your article to production in TC. You will soon be contacted by the responsible production officers with regard to typesetting and reviewing the proofs before final publications.

Best,

Johannes Fürst
