Background

Global climate change is one of the greatest challenges facing humanity. To achieve the goals of the Paris Agreement, in addition to reducing greenhouse gas emissions, it is necessary to adopt negative emission technologies to actively remove carbon dioxide from the atmosphere. The ocean, covering 70% of the Earth's surface, holds immense potential as a carbon sink. As a result, Ocean Negative Carbon Emissions Technologies (ONCET) have become a hot topic of research in recent years.



However, the large-scale application of ONCET may pose potential risks to marine ecosystems. For example, ocean fertilization could trigger harmful algal blooms and alter marine food web structures, while artificial upwelling might bring deep-sea low-oxygen waters to the surface, negatively impacting marine life. Therefore, before developing and deploying ONCET, it is crucial to conduct comprehensive ecological risk assessments and formulate corresponding risk management strategies.



The urgency of addressing climate change and exploring ONCET has been underscored by several recent events and initiatives:

The 2023 IPCC AR6 Synthesis Report emphasized the critical role of carbon dioxide removal (CDR) technologies, including ocean-based solutions, in limiting global warming to 1.5°C.

The Ocean Decade (2021-2030), led by UNESCO’s Intergovernmental Oceanographic Commission, has identified "A Clean Ocean" and "A Predicted Ocean" as key challenges, highlighting the need for sustainable ocean-based climate solutions.

The 2023 UN Climate Change Conference (COP28) resulted in unprecedented recognition and momentum for linking efforts to address the climate and biodiversity crises. The decision emphasizes “the importance of conserving, protecting and restoring nature and ecosystems towards achieving the Paris agreement temperature goal” through protecting “terrestrial and marine ecosystems acting as sinks and reservoirs of greenhouse gases and by conserving biodiversity.” This is the first time such a pledge has garnered formal recognition under the UN Framework Convention on Climate Change (UNFCCC).

Recent advancements in ONCET research, such as the development of electrochemical ocean carbon capture and the deployment of large-scale seaweed farming projects, have sparked both optimism and concerns about their ecological impacts.

Growing international collaborations, such as the Ocean Visions Biennial Summit 2023, have brought together scientists, policymakers, and industry leaders to discuss the responsible development of ocean-based CDR technologies.



This Research Topic aims to gather the latest research findings in the field of ONCET and its ecological risks, providing a platform for scientists, policymakers, and the public to exchange ideas and engage in discussions. We welcome original research articles, reviews, perspectives, and commentaries on topics including but not limited to:

• Development and application of novel ONCET

• Potential impacts of ONCET on marine organisms, ecosystem functions, and services

• Methods for ecological risk assessment and management strategies for ONCET

• Socioeconomic impacts and policy regulations related to ONCET

• Public perception and participation in ONCET

Topic editors

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

  • Yes, we would love to hear your ideas for a topic. Most of our Research Topics are community-led and suggested by researchers in the field. Our in-house editorial team will contact you to talk about your idea and whether you’d like to edit the topic. If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.

  • A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

    The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

  • As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

    You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

  • As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).

  • If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.
