mCDR with the Alaskan Mariculture Cluster

The Oceanid team is grateful to have had the opportunity to work with Alaska’s Southeast Conference, as part of the Alaska Mariculture Cluster grant, to explore climate solutions and atmospheric carbon dioxide removal (CDR) opportunities using the local natural, cultural, scientific, and economic resources.

Alaska’s cold, nutrient-rich waters, and natural circulation patterns make it an ideal location for biological mCDR solutions such kelp cultivation or ocean fertilization. 

Local phenomenon like glacial flour production and natural glacial runoff and mineral weathering offer potential for ocean alkalinity enhancement, coastal enhanced weathering, aggricultual enhanced rock weathering, and other abiotic carbon sequestration opportunities. 

More details and the full report are available on the Alaskan Mariculture Cluster website. 

The Southeast Conference has announced a new RFP for carbon removal projects in coastal Alaska, including:

• Developing a roadmap for turning Alaska into an mCDR research and development hub

• Using kelp as a biochar feedstock

• Kelp natural sloughing and carbon sequestration research

Proposals are due July 21, 2025.
