Ocean Antacid Experiments Signal Hope, Yet Hurdles in Climate Fight

Scientists led by Adam Subhas test ocean alkalinity enhancement by dispersing sodium hydroxide in the Gulf of Maine to raise surface pH and promote CO2 uptake, a potential but uncertain method to counter ocean acidification and remove carbon; while it could help in key regions, it would require massive energy, infrastructure, careful monitoring, and emission reductions, and questions about safety and long-term ecological impacts remain.

Scientists Propose Ocean Chemical Dump to Combat Climate Change

Researchers at the Woods Hole Oceanographic Institution are seeking a permit to dump 6,600 gallons of sodium hydroxide into the ocean off Cape Cod to enhance the ocean's ability to absorb CO2 and combat climate change. The plan faces opposition from regulators, fishermen, and environmentalists concerned about potential risks to marine life. The team argues that such geoengineering efforts are necessary given the slow transition away from fossil fuels.

"Ocean Alkalinity Enhancement: A Promising Solution for Carbon Dioxide Removal and Marine Life"

A study published in Science Advances explores the impact of ocean alkalinity enhancement on marine biota and its potential for carbon dioxide removal. The research focused on two important phytoplankton species, Emiliania huxleyi and Chaetoceros sp., and found that limestone-inspired alkalinity had a neutral effect on their growth rate and elemental ratios. However, high-alkalinity additions resulted in mineral precipitation that removed nutrients from the system, reducing the overall effectiveness of carbon removal. While the initial findings are promising, further research is needed to understand the long-term effects and potential risks of ocean alkalinity enhancement on marine ecosystems.
