Ocean carbon removal looks promising, but nutrient cycling could curb long-term gains

There is growing interest in the scientific community and private sector in biological approaches to marine carbon dioxide removal—strategies designed to enhance the ocean's natural ability to absorb carbon from the atmosphere. However, a study led by Megan Sullivan, a postdoctoral researcher in the University of Rhode Island's Graduate School of Oceanography (GSO), suggests that some proposals may overlook an important factor.
