Why we need a code of conduct for ocean-based carbon dioxide removal

Ken Buesseler, Margaret Leinen, Kilaparti Ramakrishna, Fei Chai, Sarah Smith, Mark Wells, Joo-Eun Yoon on World Economic Forum

The Code of Conduct put forward by the Exploring Ocean Iron Solutions forum is out: both published in Nature (paywall) and World Economic Forum. The team is proposing it as a foundation to help guide research into any ocean- or land-based CDR strategy.

Koweek (2022): Expected Limits on the Potential for Carbon Dioxide Removal From Artificial Upwelling

David A. Koweek IN: Front. Mar. Sci., 29 June 2022,

This work examines the question: Can pumping of nutrient-rich water from the deep ocean to the surface draw down CO2? The modelling study concludes that artificial upwelling is probably not likely to drawdown much CO2, resulting in very small estimates of CDR potential. Moreover, additional production supported by bringing new nutrients to the surface is almost completely offset by the release of CO2 from deep ocean water.


Ocean Carbon Conference

Thu, 14 July 2022; 10:00 – 16:00 BST by Centre for Climate Repair at Cambridge

A one day hybrid conference on ocean carbon sequestration: Marine Biomass Regeneration (MBR) is a project to regenerate biomass in the oceans and not only thereby support marine ecosystems but also enhance the drawdown CO2 from the atmosphere. The objective of the project is to emulate the role of whales which feed in the benthic waters and return to the surface to defecate. The natural biological pumping and recycling of nutrients to the surface ocean is therefore diminished.


Christianson et al. (2022): The Promise of Blue Carbon Climate Solutions: Where the Science Supports Ocean-Climate Policy

Anne B. Christianson, Anna Cabré, Blanca Bernal, Stacy K. Baez, Shirley Leung, Alicia Pérez-Porro and Elvira Poloczanska IN: Front. Mar. Sci.,

This paper gives context to numerous blue carbon sequestration pathways, quantifying their potential to sequester carbon from the atmosphere, and comparing these sequestration pathways to point-source emissions reductions. The applicability of blue carbon is then discussed in terms of multiple international policy frameworks, to help individuals and institutions utilize the appropriate framework to reach ocean conservation and climate mitigation goals.


Developing Model Federal Laws to facilitate responsible Ocean CDR Research

by Romany Webb on Climate Law Blog of Columbia Law School

The Sabin Center, with the support of Ocean Visions, is launching a new project to develop model federal laws that would function to facilitate research on Ocean CDR. To inform development of the model laws, the Sabin Center and Ocean Visions will co-host a series of stakeholder workshops at which members of the scientific community, representatives of government bodies, and other interested parties can provide input. If you are interested in participating in the workshops or learning more about the model laws project, please contact Romany Webb.


Recent Science in Ocean CDR

by Nori – Carbon Removal Newsroom on Spotify (43 min)

In recent episodes, the authors covered global policy developments in Ocean CDR regulation and research with Wil Burns and the business challenges in the space with two startups working to develop commercial methods to remove CO2 from the ocean. On this episode they complete the trilogy with a look at some recent science on the topic, focusing on the outstanding scientific questions that will need to be answered before Ocean CDR can be deployed safely and effectively.


Ocean Visions and Running Tide announce the formation of independent Scientific Advisory Board

….convened and managed by Ocean Visions to guide the development of Running Tide’s carbon removal system. Included in this expert group will be:

  • Dr. Jim Barry, Senior Scientist and Benthic Ecologist at the Monterey Bay Aquarium Research Institute and a leading expert in benthic marine environments.
  • Dr. Andreas Oschlies, Head of the Biogeochemical Modelling research unit at GEOMAR Helmholtz Centre for Ocean Research and a leading expert in oceanic carbon uptake.
  • Richard Donovan, a co-founder of the Forest Stewardship Council (FSC) and independent forest advisor with 45+ years’ experience in community forest enterprises, rural development, forest certification, community forestry, watershed management, and biomass energy.
  • David Bannon, Board Member and Founder of Headwall Photonics, a leading designer and manufacturer of imaging sensors and spectral instrumentation and an expert in the deployment of advanced instrumentation for remote sensing and machine vision.
