Adding natural alkaline substances to seawater can boost the ocean’s ability to absorb carbon dioxide – but scientists warn there may be processes in the ocean system that alter its efficiency.
Ocean alkalinity enhancement (OAE) aims to accelerate the relatively slow weathering processes that occur naturally on land and in the coastal ocean, by grinding up alkaline minerals such as silicate and carbonate rocks and dispersing them across the ocean surface.
In a new study published in Nature Geoscience, scientists from the University of Tasmania’s Institute for Marine and Antarctic Studies (IMAS) took a closer look at how OAE could change ocean chemistry and how this could affect marine organisms in their surrounding environment.
