Paper on Deep-ocean Sinking of Seaweed for Carbon Sequestration

Posted on by

The following Commentary Paper entitled “Deep-ocean seaweed dumping for carbon sequestration: Questionable, risky, and not the best use of valuable biomass”, written by members of the UN Global Compact Global Seaweed Coalition’s Scientific Council, provides the current state of knowledge on sinking seaweed for carbon sequestration.

The authors argue that deep-ocean seaweed dumping is not a biological, environmental, economic, societal or ethical answer to climate-change mitigation via carbon “sequestration”. It is presently not based on sound science.

2020 Symposium

1st National Seaweed Symposium

The first national Seaweed Symposium sponsored by 10 NOAA Sea Grant programs, brought together 120 seaweed stakeholders representing current and prospective farmers, regulators, federal agencies, processors, researchers, culinary professionals and non-profit groups from across the country. The group gathered to share information and better understand the current status, emerging needs and challenges, and realistic opportunities of the nascent domestic seaweed industry. Attendees were updated on the status of seaweed farming across the country and internationally, were provided with results of the national needs assessment, learned about seaweed products and the latest research during the Seaweed Showcase, and learned about farming techniques and challenges during the Farmers’ Forum. Symposium attendees then separated into the following diverse-sector topical Work Groups to collaboratively address common challenges identified in the needs assessment: Market Opportunities, Regulations, Post-harvest and Processing Infrastructure, and Production Systems. For a summary of the discussions, please refer to the Work Group section of the website.
