The study reveals that OIF promotes marine carbon sinks by adding iron to “high-nutrient, low-chlorophyll” marine regions (e.g., the Southern Ocean), which enhances the photosynthesis of surface phytoplankton and thereby increases marine carbon sinks. In contrast, AOA improves seawater alkalinity by adding alkaline materials (such as limestone) to the ocean; through carbonate chemical processes, this method drives the ocean to absorb more CO2 from the atmosphere.
