Ocean geoengineering experiment south of Martha’s Vineyard, designed to suck carbon from atmosphere, delayed

However, after scheduling delays related to the federal permitting process, the research institution said that the research vessel needed for the experiment is no longer available. 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...
