Dear authors,

Thanks for submitting the revised manuscript. For the official record, I would like to note the change of coatuhorship. One coauthor contacted to journal's office to opt out from the paper. The corresponding author agreed to remove that coauthor from the paper, and provided the evidence of consent from all the other authors.

Now I am going to send out the manuscript for another review round.

Dear authors,

The revised manuscript is now reviewed by one referee and myself. I echo referee’s view; your revision is satisfactory. There are only a few more points that I would like to suggest to change. Please revise the manuscript further to respond to referee’s and my comments, and submit the revised manuscript with a markup manuscript. Your response letter is needed only if you rebut.

Page/line numbers refer those in the mark-up manuscript.

P2L50: duplicated definition of GlaDS

P3L60: KOPRI and UTIG were defined at L25 above. So, remove this duplicated part.

P4L91: typo, unit for the density, kg m-3

L121: do not show abbreviation multiple times. Once defined, use the defined abbreviation.

L128: What does “following geothermal flux rate calculations”? I think the authors want to say “following subglacial melt rate calculations.”
Fig. 2 caption: elevations can be lower, but not deeper. And then from what is it lower by 500 m? Sea level?

Fig. S4: the second panels for profiles A-A’ and B-B’ should be labeled as Elevation (m), not depth. Also check the high spike of the ice-shelf surface near Martin Peninsula in profile A-A’ (typo in the label “Marin Peninsula”).

Fig. S5: Are two red vertical lines shown correctly? For that plot for ship-based bathymetry, RMSE is 120.82 m. And what’s the point to show it only in the lower panel?

Fig. S6: add locations of CTD casts (shown in Fig. 1 though)

In data availability, it is said that the derived data products are posted at Zenodo.org but the given URL lead readers to “closed access” page. Please update that page and release the data. Similarly, update the status of data submission for helicopter gravity data. It is said “will be deposited”. I assume that it means that the data are released upon the acceptance of this paper.

Also author contributions should be updated. A.W. opted out.
