Common Questions

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.

The MarXiv repository is located at

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.

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

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.

How should I license my work in MarXiv?

Note: ASAPbio has an excellent Preprint Licensing FAQ.

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.

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 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:

You can browse and search through all 2.1+ million papers in the OSF Preprints framework at

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:

How do I edit and re-submit a paper that was rejected from MarXiv?

We have a short video walk-through available on both Vimeo and YouTube.

  1. Login to your OSF Account on MarXiv
  2. Click My OSF Projects in the top-right
  3. In the Collections sidebar on the left, click All my preprints to show your preprint files
  4. Click the title of the preprint you would like to edit
  5. Click Moderator feedback to see why your paper has been rejected
  6. Click the Edit paper button to edit your preprint
  7. You may now make any requested changes to your paper
    1. If you need to submit a different version of your preprint file, your new paper must have the exact same file name as your original paper in order to create a new version
  8. When you are done making changes, click the Return to paper button at the bottom
  9. Email Nick Wehner that you have made the requested changes (the OSF Preprints framework does not tell moderators when papers have been updated, so we will not know to re-evaluate your submission unless you tell us)
  10. That's it – thanks!
