This is an interactive tool for exploring the efficiency of direct ocean removal (DOR). You can explore global patterns, or select a polygon region to see how extracting CO₂ from the ocean in a specific region and month will result in carbon removal over time. Read our explainer article for more details, or compare with our tool for ocean alkalinity enhancement. Developed in collaboration with [C]Worthy.

Variable
CO₂ absorbed from the atmosphere compared to the removal potential induced by extracting CO₂. This metric accounts for both ocean uptake of atmospheric CO₂ after the DOR intervention and any losses from storage of the extracted CO₂. Higher values indicate more effective carbon removal.

EFFICIENCY COMPONENTS
Reuptake is the fraction of extracted CO₂ that's replaced by atmospheric CO₂ after a DOR intervention. Storage loss is the fraction of extracted CO₂ lost to the atmosphere during transport, storage, or utilization. Combined, they represent the net efficiency of the intervention. Use the slider below to explore how storage loss impacts the efficiency of DOR.

About
[C]Worthy and collaborators developed the underlying DOR efficiency dataset, mirroring previous work done on ocean alkalinity enhancement. Together, CarbonPlan and [C]Worthy built the interactive tool, with funding from with funding from the Chan Zuckerberg Initiative, the Navigation Fund, and the Grantham Foundation for the Protection of the Environment.
