Ocean-based carbon removal

Ocean-based carbon removal involves techniques that enhance the ocean’s natural ability to absorb and store carbon dioxide from the atmosphere. Methods include boosting phytoplankton growth through nutrient addition, deploying iron to stimulate marine algae, or directly capturing CO₂ and injecting it into deep ocean waters. These processes aim to reduce atmospheric CO₂ levels contributing to climate change. While promising, they require careful research to understand environmental impacts, ensure safety, and assess long-term effectiveness. Ocean-based strategies could be a vital part of broader efforts to achieve global carbon reduction goals.
