Dear Dr. Clark,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

Please address all comments if the reviewer in detail before re-submission. 

Please submit your revised manuscript by Jan 16 2025 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org . When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

Please include the following items when submitting your revised manuscript:

  • A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
  • A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
  • An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter.

If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see: https://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols . Additionally, PLOS ONE offers an option for publishing peer-reviewed Lab Protocol articles, which describe protocols hosted on protocols.io. Read more information on sharing protocols at https://plos.org/protocols?utm_medium=editorial-email&utm_source=authorletters&utm_campaign=protocols .

We look forward to receiving your revised manuscript.

Kind regards,

Reviewer's Responses to Questions

Comments to the Author

1. Is the manuscript technically sound, and do the data support the conclusions?

The manuscript must describe a technically sound piece of scientific research with data that supports the conclusions. Experiments must have been conducted rigorously, with appropriate controls, replication, and sample sizes. The conclusions must be drawn appropriately based on the data presented.

Reviewer #1: Yes

**********

2. Has the statistical analysis been performed appropriately and rigorously?

Reviewer #1: Yes

3. Have the authors made all data underlying the findings in their manuscript fully available?

The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception (please refer to the Data Availability Statement in the manuscript PDF file). The data should be provided as part of the manuscript or its supporting information, or deposited to a public repository. For example, in addition to summary statistics, the data points behind means, medians and variance measures should be available. If there are restrictions on publicly sharing data—e.g. participant privacy or use of data from a third party—those must be specified.

Reviewer #1: Yes

**********

4. Is the manuscript presented in an intelligible fashion and written in standard English?

PLOS ONE does not copyedit accepted manuscripts, so the language in submitted articles must be clear, correct, and unambiguous. Any typographical or grammatical errors should be corrected at revision, so please note any specific errors here.

Reviewer #1: Yes

5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1:  Overall Summary:

This paper presents a fascinating application of computer simulations to model Bronze Age seafaring between Denmark and Norway. While the focus is on a specific region and time period, the methodology has significant potential for broader application by seafaring modelers, ethnographers, and experimental archaeologists working in similar contexts. It is a shame then that the authors make a claim that maritime activities “are most often illustrated merely by the addition of large arrows on a map.” Sadly, this overlooks a well-developed and sophisticated body of work already engaging in seafaring modelling. While the paper proposes novel approaches, it misses an opportunity to build on this existing corpus. Acknowledging and situating the study within the broader context of previous research would strengthen its contribution.

Recommendation:

The study presents a promising contribution to seafaring archaeology but requires revisions before publication. Addressing the methodological concerns, situating the work within existing literature, and improving the presentation of text and images would significantly enhance its impact and reach.

See attachments for full review and comments.

Revision 1

Detailed responses to both editor and reviewer has been itemised and provided in the "response to reviewers" document uploaded.

Answers to Journal Requirements.

1.Endeavour to meet style requirements, including file naming.

2. There was no additional external funding received for this study. The statement has been amended to include ‘all’ the funding or sources of support etc. etc.

3.We have removed ‘ this work is supported by…’ from Acknowledgements and are happy with the phrase ‘ this work is supported by Riksbankens etc. etc.’

4. Email and name of contact will be included (see below in answer to reviewer)

5. The referenced unpublished material by Scheen, R, has been replaced with a reference to published material. This has been addressed in the manuscript.

6. Original copyright holder of Figures 1,2,3,4,8,10,11 and 26. These maps have been made by extrapolating data from SGU (https://www.sgu.se/produkter-och-tjanster/kartor/kartvisaren/jordkartvisare/strandforskjutningsmodell/), using a model by Påsse and Daniels 2015. The maps have been manipulated and created by Ashely Green and Boel Bengtsson, using ArcGIS Pro and Inkscape. Thus original copyright holders are Ashely and Bengtsson. In figure 3, two landscape drawings are included. Although in both cases the artists have been deceased for over 100 years, we have gained specific permission from Kristian Jensen, editor at Jysk Arkæologisk Selskab (this email will be uploaded for you to view). The other drawing here, showing Bulbjerg, is collected from an open source (https://commons.wikimedia.org/wiki/File:Bulbjerg-Skarreklit_JTH.jpg?uselang=en#Licensing), stating it is under no copyright restrictions for use.

7. Fhotos in figures 5 and 12 are taken by the lead author, Boel Bengtsson, and can be published under the CC BY 4.0 license.

8. All figures will be updated and resubmitted ensuring a high level of detail is retained using PACE .
