Dear authors,

Thank you for your comments to the reviewers. The three reviewers noted that the paper is well written and compelling. Particularly, they suggest that the ensemble approach is important for better understanding Antarctica subglacial hydrology.

They also provided some comments to improve the quality of the paper. I agree with these comments and encourage you to take into account these comments in the revised paper. Particularly, the choice of thresholds and the matching criteria should be better explained to make the methodology more solid.

Best wishes,
