Short summary
This study explores the growing interest in using farmed kelp as a method of marine carbon dioxide removal, focusing on two kelp farms in the Northern Gulf of Alaska. We measured net air-sea carbon dioxide exchange using sensors placed inside and outside each farm from winter to spring 2024. One farm served as a carbon sink while one served as a source of carbon dioxide to the atmosphere. Our findings highlight the importance of site selection in modulating local carbon capture.
