We thank the Referee for the careful reading of the manuscript and the constructive comments. We address each point below.

Comment 1: The letters inside Figure 2 are barely seen. Apparently, the figure was obtained from a low-resolution chart. I recommend redrawing the figure.

We thank the Referee for pointing this out. We will redraw Figure 2 at higher resolution, ensuring consistency in font size and label readability across all figures.

Comment 2: In line 122, the authors state that "After filtering processes, accepted soundings were gridded into 7 Digital Bathymetric Models (DBMs) (Figure 3)". However, Figure 3 does not present seven DBMs. Actually, there are four multibeam mosaics.

We thank the Referee for this comment. We clarify that Figure 3a displays the complete dataset, integrating all seven DBMs into a single overview map. Panels b through e show four selected examples of seafloor morphology, one per expedition Leg, chosen to illustrate the diversity of geomorphological settings captured by the survey. We recognise the potential ambiguity and will revise the figure caption and the corresponding text to make this distinction explicit.

Comment 3: It would be interesting to see more examples, each with at least a brief explanation of the features (channels, pockmarks, slumps, etc.).

We thank the Referee for this suggestion and agree it would strengthen the manuscript. We will expand Figure 3 with additional example panels, each accompanied by a brief description of the main geomorphological features visible, such as submarine channels, mass-wasting deposits, and other relevant morphologies identified across the dataset.

We are grateful to the Referee for the time dedicated to reviewing this manuscript and for the valuable comments, which we believe have contributed to improving the clarity and quality of the work.

We thank the Community Referee for the kind words and the positive assessment of the dataset and its scientific value. We address the comment on the title below.

Comment: The title feels a bit of an overstatement [...] I would simply suggest replacing "first" with "a new" or "a comprehensive".

We thank the Community Referee for this thoughtful observation. We acknowledge that several high-quality multibeam datasets exist for the deeper parts of the Saudi margin, all of which are cited in the manuscript. However, we would like to clarify that the intended meaning of "first" refers specifically to the regional-scale coverage achieved within a single, dedicated expedition, rather than through the cumulative result of multiple independent campaigns. Furthermore, as the Referee notes, the shallow coastal zone targeted here represents novel coverage. We will carefully consider this comment in the context of the full discussion and will revise the title accordingly if needed.

We are grateful to the Community Referee for the time dedicated to evaluating this manuscript and for the constructive input.

We thank the Community Referee for the thorough and positive evaluation of the manuscript and for the constructive suggestions. We address each point below.

Comment: Adding references to other recently published datasets from European basins (Napoli Bay, Puck Bay, Southern Baltic Sea).

We thank the Referee for these suggestions. We agree that these works represent highly relevant contributions, both in terms of methodology and results. We will incorporate these references into the manuscript to better contextualise our dataset within the broader global effort of high-resolution MBES surveys.

Comment: "it is strongly recommended to add at least the following to the manuscript: 1) A small summary statement in the Conclusion section that would put the paper into a wider context of global bathymetry; 2) Small addition to the Introduction section contrasting regional and global bathymetry datasets."

We thank the Referee for this valuable suggestion. We fully agree that explicitly situating the dataset within the context of global seabed mapping efforts would strengthen the manuscript. We will therefore: 1) add explicit references to Seabed 2030 in the manuscript; 2) include a brief addition to the Introduction contrasting regional and global bathymetric products; 3) add a closing statement in the Conclusion highlighting the relevance of this dataset to ongoing global mapping initiatives such as Seabed 2030.

We are grateful to the Referee for the time dedicated to evaluating our manuscript and for the constructive inputs, which we believe will broaden the reach and impact of this work.
