Submit a Paper

Are you ready to submit your work to MarXiv? Great! Please review these Submission Guidelines and our Code of Conduct before submitting your paper.

MarXiv (rhymes with "archive") is the free research repository for the ocean and climate sciences. We accept preprints, Open Access publications, reports, conference proceedings, and other scholarly documents. See What can I post to MarXiv? for more information.

The MarXiv repository is located at https://marxiv.org/.

All documents added to MarXiv are immediately publicly accessible. However, the MarXiv Team reviews all submissions. In the event your submission violates our Submission Guidelines, your paper will be removed from MarXiv. Violations of the MarXiv Code of Conduct may result in a permanent ban from sharing content in MarXiv.

MarXiv is made possible thanks to support from the David and Lucile Packard Foundation. The MarXiv repository would not exist without the Center for Open Science, which created the OSF Preprints framework on which MarXiv is built. The MarXiv project is coordinated by OCTO. See the Team page for more information on the people behind MarXiv.

Ready to submit?

All you have to do is go to the MarXiv repository on OSF Preprints and click the "Add a Paper" button. It's quite simple!

Before you post your paper to MarXiv, be sure that a) you have the rights to share your paper in MarXiv, and b) you have consent from all Contributors (i.e. coauthors) to share the work.

For more information on determining if you have the rights to share your paper in MarXiv, see Common Questions below. Generally speaking, most journals will allow you to submit your preprint to MarXiv at any time, but you'll need to wait a year or two to publicly share your postprint. This is an example of a preprint in MarXiv, and this an example postprint. Please convert your Word document to a PDF before submitting to MarXiv.

In most cases when publishing in pay-walled academic journals, the author signs a Copyright Transfer Agreement (CTA) which transfers the copyright held by the authors of the paper to the journal's publisher. This means that although you may have written a paper almost entirely by yourself, you no longer hold the copyright on your research. This restricts how you may use and share your work.

Unless your work is published Open Access or you have negotiated additional rights to share your research, it is usually illegal to share the final PDF (commonly called the Version of Record) in any public forum. You may not share the copyrighted Version of Record in MarXiv, on public websites, or on listservs.

However! Most publishers allow you to share the manuscript you submitted to the journal, commonly called the preprint, in not-for-profit subject-matter-specific repositories like MarXiv at any time. Note that services like ResearchGate and Academia.edu are both for-profit and not limited to a set of subject areas — so in many cases, it is illegal to share your preprint in ResearchGate, etc.

Additionally, most publishers allow authors to publicly share the postprint — also known as the Author's Accepted Manuscript (AAM) — in MarXiv after a 1-2 year embargo period. See our list of Self-Archiving Policies of Major Journals for a handy guide to postprint embargo periods.

The MarXiv Team hosts regular training webinars to teach you about preprints, postprints, and how to share your research in MarXiv. Register for a training webinar today or view our list of archived trainings.

Step-by-step instructions for uploading your paper to MarXiv

We have a short video showing how to upload your paper to MarXiv available on Vimeo and YouTube.

  1. Visit the MarXiv repository at https://marxiv.org. and click the "Add a paper" button.
  2. Login with your OSF Preprints account, or create a new account for free. If you have an ORCID account you may sign-in with that, instead. Many universities have partnered with OSF, so you may be able to login with your institutional credentials, too.
  3. Use the Upload section to first upload a PDF of your paper, and then give it a Title.
  4. Select the discipline(s) and subdiscipline(s) which categorize your work.
    • For example, you might choose the top-level "Social and Behavioral Sciences" discipline along with the subdisciplines of "Public Affairs, Public Policy and Public Administration" and "Environmental Policy."
    • If the discipline for your work is missing, or if you have questions on how to categorize your work, please contact us.
  5. Select a license for your work.
  6. If you have a DOI for your work already, please include that so the preprint may link-up with the peer-reviewed version of your manuscript.
  7. Provide an abstract for your work.
  8. Provide keywords or "tags" to make your work easily discoverable.
  9. Add the authors to your work. If the other authors do not have OSF Accounts, they will be invited to create one after this step is completed.
  10. Click "Submit" to post your paper on MarXiv. Congratulations! Your work is now available on MarXiv!

Need help finding your postprint/Author Accepted Manuscript (AAM)?

Publishers typically keep AAMs for 2-5 years in their Journal Submission Systems. For instructions on how to download your AAM from various publishers, use this handy guide.

Special note for government employees

Employees of the US Federal Government, Washington, D.C. & US Territories

Under 17 U.S.C. §105 all works "prepared by an officer or employee of the United States Government as part of that person’s official duties" cannot be copyrighted and are thus part of the Public Domain in the United States. This means that you can share whatever version of your paper that you want! Since you cannot copyright your work, you cannot transfer a copyright that does not exist to a publisher. Congrats!

Employees of the government of Washington, D.C. and the governments of US territories (e.g. Puerto Rico) are also covered by 17 U.S.C. §105.

Canadian Government Employees

Just like in the case of US Federal Government employees mentioned above, "authors may not waive or transfer Crown copyright in an automated online process or via a “transfer of rights” form provided by a publisher" (see page 13). Specially, the Copyright Act states that "Copyright shall belong to Her Majesty the Queen in Right of Canada ('the Crown') and shall continue for the remainder of the calendar year of the first publication of the work and for a period of fifty years following the end of that calendar year.” In plain English, that means your work cannot be copyrighted by your publisher, so you can share whatever version of your paper that you want! Congrats!

Employees of other governments

Just like the US and Canadian federal governments, several other countries prohibit copyright on works created by those governments. For example, the UK government has special copyright policies for Crown copyright and Parliamentary copyright. If you are an employee of your country's central government, please check your applicable laws to make sure your work is licensed properly. There is a good chance your work cannot be copyrighted by third-parties (i.e. academic publishers) which would mean you could share your work in MarXiv regardless if it has been formally published elsewhere.

Common Questions

What can I post to MarXiv?

  • Preprints: When you submit a manuscript to a journal for peer-review and publication, you should also submit the same manuscript to MarXiv right away.
  • Postprints: If you have the rights to share your postprint in a repository like MarXiv, please do so!
  • Reports: By sharing your group's reports in MarXiv, you'll get a unique DOI, and ensure your report is indexed by Google Scholar and other academic indexes.
  • Theses and dissertations: Ensure people can find your thesis or dissertation by archiving it in MarXiv! This may come as a surprise: some of the most downloaded papers in MarXiv are theses (including two from the OCTO Team who thought no one would ever read their theses, ever).
  • Working papers, conference proceedings, abstracts, posters, etc.: MarXiv will gladly accept other scholarly research outputs.
  • Open Access publications: Have you already published an Open Access paper? If you have a Creative Commons license, or similar, you can share the work in MarXiv.

MarXiv especially requests manuscripts of negative results! Negative results are one of the most sought-after works in ocean conservation and are rarely published by traditional journals. You can learn a lot from successful studies, but you can often learn a lot more from unsuccessful ones.

Please note that MarXiv only accepts works pertaining to the ocean and marine-climate sciences.

If you have questions regarding if MarXiv will accept your work, please contact us.

What is a preprint or postprint?

Generally speaking, a preprint is the manuscript submitted to a scholarly journal which will undergo peer review before being formally published. Preprints may also be known as an "original manuscript" in some journals. This is an example of a preprint in MarXiv.

The postprint is the edited and peer-reviewed, but not yet typeset, version of the manuscript. Postprints may also be known as a "corrected proof" or "accepted manuscript" in some journals. This is an example of a postprint in MarXiv.

For a quick primer on preprints, watch this 4-minute YouTube video. The Open Access Button also has a handy guide to help you determine the difference between preprints, postprints, and the publisher's PDF.

The typical academic publishing workflow begins with a manuscript submitted to a journal for peer-review and publication. This manuscript is known as the preprint. The preprint will then undergo peer-review and editing between the author, peer reviewers, and the journal editor. At this point, when the manuscript is peer-reviewed but not typeset by the publisher, the author is asked to sign a Copyright Transfer Agreement (CTA). The CTA then transfers the copyright held by the author on all forms of the manuscript (both pre- and post-peer-review) to the publisher. Before signing the CTA, we recommend authors utilize an Author Addendum to negotiate with the publisher that the author should keep full copyright on the peer-reviewed (but not typeset) manuscript. After the CTA is signed, the publisher will generate a rough-draft of the typeset and peer-reviewed manuscript, known as the postprint. After typesetting edits are made, the final publisher's PDF is created, known as the Version of Record (VOR). The VOR is what users typically download from the publisher. Some publishers make postprints available for download as an "early view" of the publication.

What is a Copyright Transfer Agreement?

A Copyright Transfer Agreement (CTA) is legal document which is generally used by publishers to "transfer" copyright on a manuscript from the author(s) to the publisher. CTAs may transfer some or all legal rights. In the end, this means the authors do not have full legal copyright on the manuscript which they produced — instead, the publisher is given these rights.

When publishing in a traditional pay-walled academic journal, the CTA will define how the author may use their manuscript. Authors may be allowed to deposit their preprint in MarXiv immediately. Or, authors may only be allowed to share their preprint after an embargo period. Every CTA is unique. We encourage all authors to consult their CTA to determine how they can legally share their work.

If you published in a traditional pay-walled academic journal, but paid for "gold" Open Access (usually identifiable with a Creative Commons license on the final document) then you may not have signed a CTA since you (the author) retains final copyright.

The SHERPA/RoMEO database of publisher copyright and self-archiving policies may help you determine which journals allow preprints to be posted publicly. Please note, however, that SHERPA/RoMEO should not be considered 100% accurate and all claims made by SHERPA/RoMEO should be verified by your CTA.

How do I determine if I have the legal rights to share my paper in MarXiv?

If you have not published your work elsewhere, you should retain full copyright on the work, and thus you can share your work on MarXiv. Congratulations!

If you have published your work already, you will need to ensure you have the legal rights to post your work in MarXiv. If you published your work with no license or a Creative Commons license, you may share your work in MarXiv.

If, however, you published in a traditional pay-walled journal (by publishers like Springer Nature, Wiley, Oxford Press, etc.) then you have transferred your copyright to your publisher. Your publisher can (and will) place restrictions on what you can do with your work now that they hold your copyright. You may browse our list of Self-Archiving Policies of Major Journals which will help you determine the default sharing policies of your journal/publisher.

If you have published with Elsevier: You may share your postprint in MarXiv without any embargo period. Congrats!

Ideally, you should consult your Copyright Transfer Agreement (CTA) to identify which rights you have kept. Your CTA will outline which rights you (the author) have transferred to the publisher and which rights you (the author) have retained.

How should I license my work in MarXiv?

Note: ASAPbio has an excellent Preprint Licensing FAQ. Daniel Himmelstein also wrote a nice blog about bioRxiv's licensing options, and how authors can best protect their own rights by utilizing CC-By licenses.

MarXiv allows for the following licenses:

  • CC-By Attribution 4.0 International
  • No License
  • GNU Lesser General Public License (LGPL) 3.0
  • Eclipse Public License 1.0
  • CC-By Attribution-ShareAlike 4.0 International
  • CC-By Attribution-NonCommercial-NoDerivatives 4.0 International

By default, all MarXiv submissions are granted a CC-By Attribution 4.0 International license. This license allows others to share and adapt your work, as long as they cite you. Citing allows others to build off your work while crediting you, which is generally how academic literature operates. The MarXiv teams suggests you use this license, but you are welcome to choose otherwise.

Selecting "No License" grants full copyright to the author(s). We don't recommend this option since it restricts sharing your research, which is kind of the whole point of MarXiv!

The GNU Lesser General Public License (LGPL) 3.0 allows anyone "to copy and distribute verbatim copies of this license document, but changing it is not allowed."

The Eclipse Public License 1.0 is traditionally used for software.

The CC-By Attribution-ShareAlike 4.0 International license allows others to use your work, provided that if they make any derivatives of the work they use the same license.

Finally, CC-By Attribution-NonCommercial-NoDerivatives does not allow any derivatives of your work, nor does it allow for commercial use. Usage of this license should be limited to only those papers where your publisher requires it as this is a restrictive license that doesn't even allow for your work to be translated. Elsevier and Wiley require this license on postprints.

Please note that some publishers restrict how you may license your preprints and/or postprints! Nature, for example, does not allow postprints to be licensed in the Creative Commons.

For more information on why it is important to select a license for your work, the Center for Open Science hosted a 30-minute webinar on the topic.

I am about to publish my work in a traditional pay-walled journal. How can I ensure I'll be able to share my work in MarXiv?

The Scholar's Copyright Addendum Engine, provided by Science Commons, offers a template to generate an addendum to your Copyright Transfer Agreement (CTA). The addendum allows you to "retain sufficient rights to post a copy of the published version of your article (usually in pdf form) online immediately to a site that does not charge for access to the article."

MarXiv recommends that before signing a CTA, you utilize the Scholar's Copyright Addendum to generate an "Access - Reuse" agreement. If this addendum is accepted by the publisher, it will ensure you have the legal rights to post your paper in MarXiv immediately. For more information, see Author's Rights: Using the SPARC Author Addendum.

Submission Guidelines

Your Submissions

You must have the legal rights (copyright) to share your work in MarXiv. Your Copyright Transfer Agreement (CTA) is the best place to look for the specific rights you have kept, if you have published your work with a traditional publisher already.

See Archiving Policies of Major Journals for the default publisher policies on preprints and postprints. Note that your CTA may define different rights for your particular paper.

Please ensure all coauthors have been notified, and agree to, submission. Coauthors will be notified by email automatically upon submission.

Before submitting a manuscript which will go through peer review, MarXiv recommends you to add a cover page stating that your work has been submitted to a journal. Once your manuscript has been formally published, you may want to update the cover page to reflect this. If you have the legal rights to do so, you may want to update your preprint with the postprint or the final version of your work. You may use this template (PDF) for your cover page, provided courtesy of PaleorXiv.

Screening Process

The MarXiv Team reviews all submissions generally within 24 to 48 hours after posting. The author(s) will be notified by email of the decision to accept or reject the submission.

Works will be rejected from MarXiv if there is evidence of misconduct, including but not limited to: plagiarism, falsification, copyright violation, and/or violation of the Code of Conduct.

Submit from Overleaf

Overleaf users can select MarXiv in the "Journals and Services" menu to bundle their project to share in MarXiv. You may wish to use the MarXiv Submission Template to format your paper, although this is not a requirement.

Other Questions

What is this site for?

This site is for documentation and educational materials to help you ensure you have the legal rights (copyright) to share your research in MarXiv. When publishing with traditional pay-walled journals, authors typically transfer their copyright to the publisher. Thus, as the author of a pay-walled publication, you often lack the legal rights to share your own research. However, you are typically left with limited rights. Even with limited rights, you are typically allowed to share your submitted manuscript (the preprint) in MarXiv immediately, and the peer-reviewed but not typeset manuscript (the postprint) after an embargo period.

The MarXiv repository itself is hosted by our partners at the Center for Open Science at https://marxiv.org/.

Why is MarXiv needed?

Ocean managers, policymakers, and NGOs routinely face barriers to scientific knowledge: they simply can't afford costly subscriptions to traditional peer-reviewed academic journals. Studies have found that these financial barriers result in less primary science being used in on-the-ground environmental management plans.

MarXiv offers a way to increase access to pay-walled academic literature in a legal manner. An author who retains copyright on their submitted manuscript, known colloquially as a preprint, may upload the manuscript to MarXiv. Anyone may then download and read the preprint free of charge, legally, forever.

For more information, read our blog, Why MarXiv Matters: How financial barriers to research impair ocean conservation.

Is a preprint considered "Prior Publication"?

Usually, no.

Journals published by Elsevier do not consider preprints to be "multiple, redundant or concurrent publication" thus, you may share your preprint prior to acceptance without the risk of your manuscript being rejected for this reason.

PNAS holds nearly the same opinion: "it has been PNAS policy that [preprints] do not constitute prior publication."

Science states: "Distribution on the Internet may be considered prior publication and may compromise the originality of the paper as a submission to Science, although we do allow posting of research papers on not-for-profit preprint servers such as arxiv.org and bioRxiv."

We have a short video answering this question available on Vimeo and YouTube.

You can browse for all papers in MarXiv by simply clicking the "search" button without any text in the search bar, or via this link: https://marxiv.org/discover.

You can browse and search through all 2.1+ million papers in the OSF Preprints framework at https://osf.io/preprints/discover.

What are the free (no-APC) Open Access journals for the marine sciences?

The Directory of Open Access Journals (DOAJ) lists a number of free, no-APC, "Gold Open Access" journals for the marine sciences. These include:
