The following paper by Wataru Nakamura, Ph.D. candidate, et al. has been published in the international journal Marine Environmental Research.
The paper is an outcome of joint research project with Nippon Steel Corporation to create a shallow-water seagrass bed ecosystem using calcified soil made from steel slag and dredged soil in a mesocosm tank at the company's research institute. The calcified soil was found to be effective in promoting atmospheric carbon uptake by raising the pH and lowering the partial pressure of carbon dioxide (pCO2) through alkaline leaching. This is expected to be one of the methods to create blue carbon ecosystems.
