- Researchers report that adding sodium hydroxide to seawater triggered measurable uptake of carbon dioxide from the atmosphere within days.
- This result shows that deliberate changes to ocean chemistry can draw carbon from the air without detectable harm to nearby marine life.
- A drifting patch of chemically altered seawater in the Gulf of Maine revealed the change as scientists tracked how carbon moved between air and ocean.
- By measuring those shifts, Adam Subhas at Woods Hole Oceanographic Institution demonstrated that the surface ocean began drawing carbon dioxide out of the atmosphere.
