Re-carbonizing the sea: Scientists to start testing a big ocean carbon idea

„Ocean alkalinity enhancement (OAE) involves releasing certain minerals into the ocean, sparking a chemical reaction that enables the seawater to trap more CO₂ from the air and mitigating, albeit temporarily, ocean acidification. Some scientists believe OAE could be a vital tool for drawing down and securely storing some of the excess CO₂ humanity has added to the atmosphere that is now fueling climate change. Yet many questions about OAE remain, including most prominently how it would impact marine life and ecosystems. Several programs are aiming to spark the research needed to answer these questions, including field tests in the ocean.“
