Navigating Potential Hype and Opportunity in Governing Marine Carbon Removal [PDF]

Frontiers in Climate, 2021
As the technical and political challenges of land-based carbon dioxide removal (CDR) approaches become more apparent, the oceans may be the new “blue” frontier for carbon drawdown strategies in climate governance.

Oyster farming acts as a marine carbon dioxide removal (mCDR) hotspot for climate change mitigation. [PDF]

Proc Natl Acad Sci U S A
Bivalve farming, a vital component of global aquaculture, has been proposed as a potential marine carbon dioxide removal (mCDR) strategy, yet its role remains contentious. Using field mesocosms, we demonstrate that oyster filter-feeding enhances mCDR by accelerating the formation of particulate and dissolved organic carbon in the water ...

Metrics for quantifying the efficiency of atmospheric CO2 reduction by marine carbon dioxide removal (mCDR)

Environmental Research Letters
Marine carbon dioxide removal (mCDR) is gaining interest as a tool to meet global climate goals. Because the response of the ocean–atmosphere system to mCDR takes years to centuries, modeling is required to assess the impact of mCDR on atmospheric CO _2 ...

On the Efficiency and Durability of Purposefully Sinking Seaweed Biomass as a Marine Carbon Dioxide Removal Strategy

Earth's Future
Large‐scale farming and purposeful sinking of seaweed has been suggested as a marine Carbon Dioxide Removal (mCDR) strategy. Farmed seaweed uptakes dissolved inorganic carbon (DIC) from the mixed layer, resulting in a CO2 deficit that causes an influx of
