August 15, 2024 — A controversial geoengineering experiment planned for an area of open ocean water southwest of Martha’s Vineyard will be delayed until 2025, the research institution leading the project announced Wednesday. It had been set to begin this September.
The Woods Hole Oceanographic Institution, a private marine research nonprofit organization, had planned to release a 6,600-gallon mixture of sodium hydroxide solution and freshwater into the Atlantic in a first-of-its-kind experiment. The intent is to learn whether the method — known as “ocean alkalinity enhancement” — can temporarily change the chemistry of the water, thereby raising the amount of carbon dioxide that is absorbed by the ocean and helping to fight climate change.
However, after scheduling delays related to the federal permitting process, the research institution said that the research vessel needed for the experiment was no longer available.
