Special Issue Information
Dear Colleagues,
Anthropogenic global warming and terrestrial nutrient input are causing significant deoxygenation in the ocean that is fundamental to most marine lives. Intense marine deoxygenation also occurred in the geological past, which caused strong disturbances to the carbon cycle and climate change and may provide insights into understanding the ecological and climatic effects of current deoxygenation. However, the mechanisms behind deoxygenation are complex, involving biogeochemical processes across different temporal and spatial (horizontally or vertically) scales, and the proxies for paleo-ocean deoxygenation are mostly qualitative, and sometimes even ambiguous. This poses a significant challenge for reconstructing marine deoxygenation against the backdrop of global cooling in the Cenozoic Era—which is generally unfavorable for ocean deoxygenation.
This Special Issue encourages contributions that enhance our understanding of the nature, drivers, and timing of changes in the Cenozoic ocean oxygen dynamics globally and/or locally and across various timescales (modern to multimillion year) from geological archives and/or modern settings.
Topics of interest for publication include, but are not limited to, the following:
- Proxy identification, calibration, and application for deoxygenation.
- The relationship between natural archives of recent marine deoxygenation and human impact.
- The response of past ocean deoxygenation to climatic change in the Cenozoic Era.
- The links of past ocean deoxygenation to the carbon and nutrient cycling.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Marine Science and Engineering is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
