Dear Authors,

thank you for the replies to the reviews. I encourage you to submit a revised version, implementing the changes in your response-to-reviews. Given that the criticism on the initial version was substantial, this will then be re-reviewed.

Kind regards, Reinhard Drews

Dear Authors,

thank you for submitting your revisions. The reviewer's have raised substantial criticism in the initial round. The revised version was positively received, and I agree with the reviewers that this much improved paper is now almost ready for publication in TC. Congratulations for a hard piece of work that is yet another step forward in understanding the mechanics of Whillans Ice Stream.

Please respond to the minor concerns raised by RV-2 and incorporate the suggested editorial remarks. Please also make sure that all Figures are placed as intended. RV-1 has mentioned possibly missing Figures that appear in the response-to-reviews but did not make it into the final version (I think they did, but just make sure that this is indeed the case).

Kind regards,
-- Reinhard Drews

Minor edits
-------------

Eq (6) appears misplaced (should be close to l. 17 on p. 9).

Table 2 add units.

Table 3 add units.

Dear Authors,

thanks for the last round of minor revisions. We can now move on to typesetting, where you should consider some minor minor changes to Fig. 7 (see comments below). Congratulations for this paper which adds yet another puzzle piece to our understanding of relevant grounding-zone processes.

Kind regards, Reinhard Drews


Fig. 7 labels "O.c." -- > "O.c."

In captions "(A)" --> " (A)"

Fig. 7D check rightmost x-label "0 km". Looks like as if it should it be "13 km" or something like that.
