This important study evaluates the impacts of enhanced olivine weathering on globally relevant phytoplankton species. Results from the study indicate that olivine dissolution products are unlikely to negatively impact the six phytoplankton species tested and may even enhance growth under certain conditions. Studies examining the safety of ocean alkalinity enhancement are urgently needed as interest in deploying this strategy for carbon dioxide removal is increasing.

Short summary
Applications of the mineral olivine are a promising means to capture carbon dioxide via coastal enhanced weathering, but little is known about the impacts on important marine phytoplankton. We examined the effects of olivine dissolution products on species from three major phytoplankton groups: diatoms, coccolithophores, and cyanobacteria. Growth and productivity were generally either unaffected or stimulated, suggesting the effects of olivine on key phytoplankton are negligible or positive.
