The authors have done a great job in responding to the reviewers' comments, and have resolved all of the issues satisfactorily. I have found a few minor typos to correct and two adjustments to make the text more accessible before final publication:

Page 4 line 9: equivalence should be equivalent
Page 6 line 23-24: To help readers new to this kind of work can you add one sentence here just to say how Jakobsson et al. (2016) used the multibeam echo-sounder data to map the terraces. e.g. "scarps were identified in images from shading" or something equivalent.
Page 7 line 7: if possible be more precise than "far fewer"
Page 7 lines 14-15 you say "Multibeam water column information was logged and analyzed for two-thirds of the surveyed area east of Askö. Seeps from the seafloor were found to be a common feature", so please just add a sentence either here or in the methods (Pages 3-6) for readers not expert in this domain how seeps are identified from multibeam water column information.
Page 9 line 17: this title should be "Discussion and Conclusions"
Page 13 line 28: "how small blocks of clay presently are falling down" should read "that small blocks of clay are presently falling down"

Figure 5: adjust the caption slightly to read at the end: Bottom photographs are shown in (d-e) and a 3D-photo mosaic of this terrace in (f).

Thank you to the authors for their careful revision of the manuscript that I now find suitable for publication. I'd like to extend my thanks to the two reviewers for their constructive comments.

Dear Martin Jakobsson,
Associate editor Susan Conway advises that your manuscript is now ready for publication in ESurf. I am happy to act on her advice and approve publication. Thank you for working efficiently with our associate editor and her referees. The outcome is an original look at two normally hidden features: submarine topography and groundwater seepage. I am pleased that you have chosen ESurf and look forward to seeing your paper in its final form.
Please do respond promptly to any messages from our Copernicus publishers to expedite the preparation of the publication.
Sincerely,
Niels Hovius
