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 (in press) 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 and Environmental Defense Fund.
