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

About

[C]Worthy and collaborators developed the underlying OAE efficiency dataset. Together, CarbonPlan and [C]Worthy built the interactive tool, with funding from the Carbon to Sea Initiative (via Windward Fund) and Environmental Defense Fund.
